Centos7基础组件环境部署

  1. 简述

    记录Centos7环境下,常用基础组件环境部署。并将针对每个组件更新相关操作文章。

    序号 组件 日常操作
    1 Nginx
    2 Redis
    3 Mysql
    4 RabbitMQ
    5 Kafka
    6 Minio
  2. Nginx

    Nginx是一款轻量级的服务器/反向代理服务器及电子邮件(IMAP/POP3)代理服务器,在BSD-like 协议下发行。其特点是占有内存少,并发能力强,事实上nginx的并发能力在同类型的网页服务器中表现较好。
    Nginx由俄罗斯开发者开发,但目前隶属于美国F5公司。考虑国产化替代可选用BES WebServer(宝蓝德)、TheTengineWebServer(淘宝Tengine)

  3. Redis

    Redis是一种基于内存存储的非关系型数据库(NOSQL),可用于缓存和消息代理。Redis提供数据结构,例如字符串,哈希,列表,集合,带范围查询的排序集合,位图,超日志,地理空间索引和流。Redis具有内置的复制【集群】,Lua脚本,LRU驱逐,事务和不同级别的磁盘持久性【磁盘】,并通过Redis SentinelRedis Cluster自动分区提供了高可用性【集群】。
    Redis7.4版本开始,Redis 将不再遵循 BSD 3-Clause 开源协议进行分发,而是采用 SSPLv1RSALv2 双重许可证。Redis 源代码将通过 Redis 社区版免费提供给开发者、客户和合作伙伴。

      # started with the file path as first argument:
      #
      # ./redis-server /path/to/redis.conf

      # Note on units: when memory size is needed, it is possible to specify
      # it in the usual form of 1k 5GB 4M and so forth:
      #
      # 1k => 1000 bytes
      # 1kb => 1024 bytes
      # 1m => 1000000 bytes
      # 1mb => 1024*1024 bytes
      # 1g => 1000000000 bytes
      # 1gb => 1024*1024*1024 bytes
      #
      # units are case insensitive so 1GB 1Gb 1gB are all the same.

      # Include one or more other config files here. This is useful if you
      # have a standard template that goes to all Redis servers but also need
      # to customize a few per-server settings. Include files can include
      # other files, so use this wisely.
      #
      # Notice option "include" won't be rewritten by command "CONFIG REWRITE"
      # from admin or Redis Sentinel. Since Redis always uses the last processed
      # line as value of a configuration directive, you'd better put includes
      # at the beginning of this file to avoid overwriting config change at runtime.
      #
      # If instead you are interested in using includes to override configuration
      # options, it is better to use include as the last line.

      ################################## NETWORK #####################################

      # By default, if no "bind" configuration directive is specified, Redis listens
      # for connections from all the network interfaces available on the server.
      # It is possible to listen to just one or multiple selected interfaces using
      # the "bind" configuration directive, followed by one or more IP addresses.
      #
      # Examples:
      #
      # bind 192.168.1.100 10.0.0.1
      bind 0.0.0.0
      #
      # ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
      # internet, binding to all the interfaces is dangerous and will expose the
      # instance to everybody on the internet. So by default we uncomment the
      # following bind directive, that will force Redis to listen only into
      # the IPv4 loopback interface address (this means Redis will be able to
      # accept connections only from clients running into the same computer it
      # is running).
      #
      # IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
      # JUST COMMENT THE FOLLOWING LINE.
      # ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      #bind 0.0.0.0

      # Protected mode is a layer of security protection, in order to avoid that
      # Redis instances left open on the internet are accessed and exploited.
      #
      # When protected mode is on and if:
      #
      # 1) The server is not binding explicitly to a set of addresses using the
      # "bind" directive.
      # 2) No password is configured.
      #
      # The server only accepts connections from clients connecting from the
      # IPv4 and IPv6 loopback addresses 127.0.0.1 and ::1, and from Unix domain
      # sockets.
      #
      # By default protected mode is enabled. You should disable it only if
      # you are sure you want clients from other hosts to connect to Redis
      # even if no authentication is configured, nor a specific set of interfaces
      # are explicitly listed using the "bind" directive.
      protected-mode yes

      # make sure to raise both the value of somaxconn and tcp_max_syn_backlog

      # TCP keepalive.
      #
      # If non-zero, use SO_KEEPALIVE to send TCP ACKs to clients in absence
      # of communication. This is useful for two reasons:
      #
      # 1) Detect dead peers.
      # 2) Take the connection alive from the point of view of network
      # equipment in the middle.
      #
      # On Linux, the specified value (in seconds) is the period used to send ACKs.
      # Note that to close the connection the double of the time is needed.
      # On other kernels the period depends on the kernel configuration.
      #
      # A reasonable value for this option is 300 seconds, which is the new

      ################################# REPLICATION #################################

      # Master-Replica replication. Use replicaof to make a Redis instance a copy of
      # another Redis server. A few things to understand ASAP about Redis replication.
      #
      # +------------------+ +---------------+
      # | Master | ---> | Replica |
      # | (receive writes) | | (exact copy) |
      # +------------------+ +---------------+
      #
      # 1) Redis replication is asynchronous, but you can configure a master to
      # stop accepting writes if it appears to be not connected with at least
      # a given number of replicas.
      # 2) Redis replicas are able to perform a partial resynchronization with the
      # master if the replication link is lost for a relatively small amount of
      # time. You may want to configure the replication backlog size (see the next
      # sections of this file) with a sensible value depending on your needs.
      # 3) Replication is automatic and does not need user intervention. After a
      # network partition replicas automatically try to reconnect to masters
      # and resynchronize with them.
      #
      # replicaof <masterip> <masterport>

      # If the master is password protected (using the "requirepass" configuration
      # directive below) it is possible to tell the replica to authenticate before
      # starting the replication synchronization process, otherwise the master will
      # refuse the replica request.
      #
      # masterauth <master-password>

      # When a replica loses its connection with the master, or when the replication
      # is still in progress, the replica can act in two different ways:
      #
      # 1) if replica-serve-stale-data is set to 'yes' (the default) the replica will
      # still reply to client requests, possibly with out of date data, or the
      # data set may just be empty if this is the first synchronization.
      #
      # 2) if replica-serve-stale-data is set to 'no' the replica will reply with
      # an error "SYNC with master in progress" to all the kind of commands
      # but to INFO, replicaOF, AUTH, PING, SHUTDOWN, REPLCONF, ROLE, CONFIG,
      # SUBSCRIBE, UNSUBSCRIBE, PSUBSCRIBE, PUNSUBSCRIBE, PUBLISH, PUBSUB,
      # COMMAND, POST, HOST: and LATENCY.
      #
      replica-serve-stale-data yes

      # You can configure a replica instance to accept writes or not. Writing against
      # a replica instance may be useful to store some ephemeral data (because data
      # written on a replica will be easily deleted after resync with the master) but
      # may also cause problems if clients are writing to it because of a
      # misconfiguration.
      #
      # Since Redis 2.6 by default replicas are read-only.
      #
      # Note: read only replicas are not designed to be exposed to untrusted clients
      # on the internet. It's just a protection layer against misuse of the instance.
      # Still a read only replica exports by default all the administrative commands
      # such as CONFIG, DEBUG, and so forth. To a limited extent you can improve
      # security of read only replicas using 'rename-command' to shadow all the
      # administrative / dangerous commands.
      replica-read-only yes

      # Replication SYNC strategy: disk or socket.
      #
      # -------------------------------------------------------
      # WARNING: DISKLESS REPLICATION IS EXPERIMENTAL CURRENTLY
      # -------------------------------------------------------
      #
      # New replicas and reconnecting replicas that are not able to continue the replication
      # process just receiving differences, need to do what is called a "full
      # synchronization". An RDB file is transmitted from the master to the replicas.
      # The transmission can happen in two different ways:
      #
      # 1) Disk-backed: The Redis master creates a new process that writes the RDB
      # file on disk. Later the file is transferred by the parent
      # process to the replicas incrementally.
      # 2) Diskless: The Redis master creates a new process that directly writes the
      # RDB file to replica sockets, without touching the disk at all.
      #
      # With disk-backed replication, while the RDB file is generated, more replicas
      # can be queued and served with the RDB file as soon as the current child producing
      # the RDB file finishes its work. With diskless replication instead once
      # the transfer starts, new replicas arriving will be queued and a new transfer
      # will start when the current one terminates.
      #
      # When diskless replication is used, the master waits a configurable amount of
      # time (in seconds) before starting the transfer in the hope that multiple replicas
      # will arrive and the transfer can be parallelized.
      #
      # With slow disks and fast (large bandwidth) networks, diskless replication
      # works better.
      repl-diskless-sync no

      # When diskless replication is enabled, it is possible to configure the delay
      # the server waits in order to spawn the child that transfers the RDB via socket
      # to the replicas.
      #
      # This is important since once the transfer starts, it is not possible to serve
      # new replicas arriving, that will be queued for the next RDB transfer, so the server
      # waits a delay in order to let more replicas arrive.
      #
      # The delay is specified in seconds, and by default is 5 seconds. To disable
      # it entirely just set it to 0 seconds and the transfer will start ASAP.
      repl-diskless-sync-delay 5

      # Replicas send PINGs to server in a predefined interval. It's possible to change
      # this interval with the repl_ping_replica_period option. The default value is 10
      # seconds.
      #
      # repl-ping-replica-period 10

      # The following option sets the replication timeout for:
      #
      # 1) Bulk transfer I/O during SYNC, from the point of view of replica.

      # disconnected.
      #
      # The bigger the replication backlog, the longer the time the replica can be

      # Note that replicas never free the backlog for timeout, since they may be

      # The replica priority is an integer number published by Redis in the INFO output.
      # It is used by Redis Sentinel in order to select a replica to promote into a
      # master if the master is no longer working correctly.
      #
      # A replica with a low priority number is considered better for promotion, so
      # for instance if there are three replicas with priority 10, 100, 25 Sentinel will
      # pick the one with priority 10, that is the lowest.
      #
      # However a special priority of 0 marks the replica as not able to perform the
      # role of master, so a replica with priority of 0 will never be selected by
      # Redis Sentinel for promotion.
      #
      # By default the priority is 100.

      # It is possible for a master to stop accepting writes if there are less than
      # N replicas connected, having a lag less or equal than M seconds.
      #
      # The N replicas need to be in "online" state.
      #
      # The lag in seconds, that must be <= the specified value, is calculated from
      # the last ping received from the replica, that is usually sent every second.
      #
      # This option does not GUARANTEE that N replicas will accept the write, but
      # will limit the window of exposure for lost writes in case not enough replicas
      # are available, to the specified number of seconds.
      #
      # For example to require at least 3 replicas with a lag <= 10 seconds use:
      #
      # min-replicas-to-write 3
      # min-replicas-max-lag 10
      #
      # Setting one or the other to 0 disables the feature.
      #
      # By default min-replicas-to-write is set to 0 (feature disabled) and
      # min-replicas-max-lag is set to 10.

      # A Redis master is able to list the address and port of the attached
      # replicas in different ways. For example the "INFO replication" section
      # offers this information, which is used, among other tools, by
      # Redis Sentinel in order to discover replica instances.
      # Another place where this info is available is in the output of the
      # "ROLE" command of a master.
      #
      # The listed IP and address normally reported by a replica is obtained
      # in the following way:
      #
      # IP: The address is auto detected by checking the peer address
      # of the socket used by the replica to connect with the master.
      #
      # Port: The port is communicated by the replica during the replication
      # handshake, and is normally the port that the replica is using to
      # listen for connections.
      #
      # However when port forwarding or Network Address Translation (NAT) is
      # used, the replica may be actually reachable via different IP and port
      # pairs. The following two options can be used by a replica in order to
      # report to its master a specific set of IP and port, so that both INFO
      # and ROLE will report those values.
      #
      # There is no need to use both the options if you need to override just
      # the port or the IP address.

      ############################## MEMORY MANAGEMENT ################################

      # Set a memory usage limit to the specified amount of bytes.
      # When the memory limit is reached Redis will try to remove keys
      # according to the eviction policy selected (see maxmemory-policy).
      #
      # If Redis can't remove keys according to the policy, or if the policy is
      # set to 'noeviction', Redis will start to reply with errors to commands
      # that would use more memory, like SET, LPUSH, and so on, and will continue
      # to reply to read-only commands like GET.
      #
      # This option is usually useful when using Redis as an LRU or LFU cache, or to
      # set a hard memory limit for an instance (using the 'noeviction' policy).
      #
      # WARNING: If you have replicas attached to an instance with maxmemory on,
      # the size of the output buffers needed to feed the replicas are subtracted
      # from the used memory count, so that network problems / resyncs will
      # not trigger a loop where keys are evicted, and in turn the output
      # buffer of replicas is full with DELs of keys evicted triggering the deletion
      # of more keys, and so forth until the database is completely emptied.
      #
      # In short... if you have replicas attached it is suggested that you set a lower
      # limit for maxmemory so that there is some free RAM on the system for replica
      # output buffers (but this is not needed if the policy is 'noeviction').
      #
      # maxmemory <bytes>

      # MAXMEMORY POLICY: how Redis will select what to remove when maxmemory
      # is reached. You can select among five behaviors:
      #
      # volatile-lru -> Evict using approximated LRU among the keys with an expire set.
      # allkeys-lru -> Evict any key using approximated LRU.
      # volatile-lfu -> Evict using approximated LFU among the keys with an expire set.
      # allkeys-lfu -> Evict any key using approximated LFU.
      # volatile-random -> Remove a random key among the ones with an expire set.
      # allkeys-random -> Remove a random key, any key.
      # volatile-ttl -> Remove the key with the nearest expire time (minor TTL)
      # noeviction -> Don't evict anything, just return an error on write operations.
      #
      # LRU means Least Recently Used
      # LFU means Least Frequently Used
      #
      # Both LRU, LFU and volatile-ttl are implemented using approximated
      # randomized algorithms.
      #
      # Note: with any of the above policies, Redis will return an error on write
      # operations, when there are no suitable keys for eviction.
      #
      # At the date of writing these commands are: set setnx setex append
      # incr decr rpush lpush rpushx lpushx linsert lset rpoplpush sadd
      # sinter sinterstore sunion sunionstore sdiff sdiffstore zadd zincrby
      # zunionstore zinterstore hset hsetnx hmset hincrby incrby decrby
      # getset mset msetnx exec sort
      #
      # The default is:
      #
      # maxmemory-policy noeviction

      # LRU, LFU and minimal TTL algorithms are not precise algorithms but approximated
      # algorithms (in order to save memory), so you can tune it for speed or
      # accuracy. For default Redis will check five keys and pick the one that was
      # used less recently, you can change the sample size using the following
      # configuration directive.
      #
      # The default of 5 produces good enough results. 10 Approximates very closely
      # true LRU but costs more CPU. 3 is faster but not very accurate.
      #
      # maxmemory-samples 5

      # Starting from Redis 5, by default a replica will ignore its maxmemory setting
      # (unless it is promoted to master after a failover or manually). It means
      # that the eviction of keys will be just handled by the master, sending the
      # DEL commands to the replica as keys evict in the master side.
      #
      # This behavior ensures that masters and replicas stay consistent, and is usually
      # what you want, however if your replica is writable, or you want the replica to have
      # a different memory setting, and you are sure all the writes performed to the
      # replica are idempotent, then you may change this default (but be sure to understand
      # what you are doing).
      #
      # Note that since the replica by default does not evict, it may end using more
      # memory than the one set via maxmemory (there are certain buffers that may
      # be larger on the replica, or data structures may sometimes take more memory and so
      # forth). So make sure you monitor your replicas and make sure they have enough
      # memory to never hit a real out-of-memory condition before the master hits
      # the configured maxmemory setting.

      ############################# LAZY FREEING ####################################

      # Redis has two primitives to delete keys. One is called DEL and is a blocking
      # deletion of the object. It means that the server stops processing new commands
      # in order to reclaim all the memory associated with an object in a synchronous
      # way. If the key deleted is associated with a small object, the time needed
      # in order to execute the DEL command is very small and comparable to most other
      # O(1) or O(log_N) commands in Redis. However if the key is associated with an
      # aggregated value containing millions of elements, the server can block for
      # a long time (even seconds) in order to complete the operation.
      #
      # For the above reasons Redis also offers non blocking deletion primitives
      # such as UNLINK (non blocking DEL) and the ASYNC option of FLUSHALL and
      # FLUSHDB commands, in order to reclaim memory in background. Those commands
      # are executed in constant time. Another thread will incrementally free the
      # object in the background as fast as possible.
      #
      # DEL, UNLINK and ASYNC option of FLUSHALL and FLUSHDB are user-controlled.
      # It's up to the design of the application to understand when it is a good
      # idea to use one or the other. However the Redis server sometimes has to
      # delete keys or flush the whole database as a side effect of other operations.
      # Specifically Redis deletes objects independently of a user call in the
      # following scenarios:
      #
      # 1) On eviction, because of the maxmemory and maxmemory policy configurations,
      # in order to make room for new data, without going over the specified
      # memory limit.
      # 2) Because of expire: when a key with an associated time to live (see the
      # EXPIRE command) must be deleted from memory.
      # 3) Because of a side effect of a command that stores data on a key that may
      # already exist. For example the RENAME command may delete the old key
      # content when it is replaced with another one. Similarly SUNIONSTORE
      # or SORT with STORE option may delete existing keys. The SET command
      # itself removes any old content of the specified key in order to replace
      # it with the specified string.
      # 4) During replication, when a replica performs a full resynchronization with
      # its master, the content of the whole database is removed in order to
      # load the RDB file just transferred.
      #
      # In all the above cases the default is to delete objects in a blocking way,
      # like if DEL was called. However you can configure each case specifically
      # in order to instead release memory in a non-blocking way like if UNLINK
      # was called, using the following configuration directives:

      lazyfree-lazy-eviction no
      lazyfree-lazy-expire no
      lazyfree-lazy-server-del no
      replica-lazy-flush no

      ############################## APPEND ONLY MODE ###############################

      # By default Redis asynchronously dumps the dataset on disk. This mode is
      # good enough in many applications, but an issue with the Redis process or
      # a power outage may result into a few minutes of writes lost (depending on
      # the configured save points).
      #
      # The Append Only File is an alternative persistence mode that provides
      # much better durability. For instance using the default data fsync policy
      # (see later in the config file) Redis can lose just one second of writes in a
      # dramatic event like a server power outage, or a single write if something
      # wrong with the Redis process itself happens, but the operating system is
      # still running correctly.
      #
      # AOF and RDB persistence can be enabled at the same time without problems.
      # If the AOF is enabled on startup Redis will load the AOF, that is the file
      # with the better durability guarantees.
      #
      # Please check http://redis.io/topics/persistence for more information.

      appendfilename "appendonly.aof"

      # The fsync() call tells the Operating System to actually write data on disk
      # instead of waiting for more data in the output buffer. Some OS will really flush
      # data on disk, some other OS will just try to do it ASAP.
      #
      # Redis supports three different modes:
      #
      # no: don't fsync, just let the OS flush the data when it wants. Faster.
      # always: fsync after every write to the append only log. Slow, Safest.
      # everysec: fsync only one time every second. Compromise.
      #
      # The default is "everysec", as that's usually the right compromise between
      # speed and data safety. It's up to you to understand if you can relax this to
      # "no" that will let the operating system flush the output buffer when
      # it wants, for better performances (but if you can live with the idea of
      # some data loss consider the default persistence mode that's snapshotting),
      # or on the contrary, use "always" that's very slow but a bit safer than
      # everysec.
      #
      # More details please check the following article:
      # http://antirez.com/post/redis-persistence-demystified.html

      # appendfsync always
      appendfsync everysec
      # appendfsync no

      # When the AOF fsync policy is set to always or everysec, and a background
      # saving process (a background save or AOF log background rewriting) is
      # performing a lot of I/O against the disk, in some Linux configurations
      # Redis may block too long on the fsync() call. Note that there is no fix for
      # this currently, as even performing fsync in a different thread will block
      # our synchronous write(2) call.
      #
      # In order to mitigate this problem it's possible to use the following option
      # that will prevent fsync() from being called in the main process while a
      # BGSAVE or BGREWRITEAOF is in progress.
      #
      # This means that while another child is saving, the durability of Redis is
      # the same as "appendfsync none". In practical terms, this means that it is
      # possible to lose up to 30 seconds of log in the worst scenario (with the
      # default Linux settings).
      #
      # If you have latency problems turn this to "yes". Otherwise leave it as
      # "no" that is the safest pick from the point of view of durability.

      # Redis is able to automatically rewrite the log file implicitly calling

      #
      # This is how it works: Redis remembers the size of the AOF file after the
      # latest rewrite (if no rewrite has happened since the restart, the size of
      # the AOF at startup is used).
      #
      # This base size is compared to the current size. If the current size is
      # bigger than the specified percentage, the rewrite is triggered. Also
      # you need to specify a minimal size for the AOF file to be rewritten, this
      # is useful to avoid rewriting the AOF file even if the percentage increase
      # is reached but it is still pretty small.

      # Redis can either exit with an error when this happens, or load as much

      # and refuses to start. When the option is set to no, the user requires
      # to fix the AOF file using the "redis-check-aof" utility before to restart
      # the server.
      #
      # Note that if the AOF file will be found to be corrupted in the middle

      # Replicas will try to get their rank by offset, and apply to the start
      # of the failover a delay proportional to their rank.
      #
      # 2) Every single replica computes the time of the last interaction with
      # its master. This can be the last ping or command received (if the master
      # is still in the "connected" state), or the time that elapsed since the
      # disconnection with the master (if the replication link is currently down).
      # If the last interaction is too old, the replica will not try to failover
      # at all.
      #
      # The point "2" can be tuned by user. Specifically a replica will not perform
      # the failover if, since the last interaction with the master, the time
      # elapsed is greater than:
      #
      # (node-timeout * replica-validity-factor) + repl-ping-replica-period
      #
      # So for example if node-timeout is 30 seconds, and the replica-validity-factor
      # is 10, and assuming a default repl-ping-replica-period of 10 seconds, the
      # replica will not try to failover if it was not able to talk with the master
      # for longer than 310 seconds.
      #
      # A large replica-validity-factor may allow replicas with too old data to failover
      # a master, while a too small value may prevent the cluster from being able to
      # elect a replica at all.
      #
      # For maximum availability, it is possible to set the replica-validity-factor
      # to a value of 0, which means, that replicas will always try to failover the
      # master regardless of the last time they interacted with the master.
      # (However they'll always try to apply a delay proportional to their
      # offset rank).
      #
      # Zero is the only value able to guarantee that when all the partitions heal
      # the cluster will always be able to continue.
      #
      # cluster-replica-validity-factor 10

      # Cluster replicas are able to migrate to orphaned masters, that are masters
      # that are left without working replicas. This improves the cluster ability
      # to resist to failures as otherwise an orphaned master can't be failed over
      # in case of failure if it has no working replicas.
      #
      # Replicas migrate to orphaned masters only if there are still at least a
      # given number of other working replicas for their old master. This number
      # is the "migration barrier". A migration barrier of 1 means that a replica
      # will migrate only if there is at least 1 other working replica for its master
      # and so forth. It usually reflects the number of replicas you want for every
      # master in your cluster.
      #
      # Default is 1 (replicas migrate only if their masters remain with at least
      # one replica). To disable migration just set it to a very large value.
      # A value of 0 can be set but is useful only for debugging and dangerous
      # in production.
      #
      # cluster-migration-barrier 1

      # By default Redis Cluster nodes stop accepting queries if they detect there
      # is at least an hash slot uncovered (no available node is serving it).
      # This way if the cluster is partially down (for example a range of hash slots
      # are no longer covered) all the cluster becomes, eventually, unavailable.
      # It automatically returns available as soon as all the slots are covered again.
      #
      # However sometimes you want the subset of the cluster which is working,
      # to continue to accept queries for the part of the key space that is still
      # covered. In order to do so, just set the cluster-require-full-coverage
      # option to no.
      #
      # cluster-require-full-coverage yes

      # This option, when set to yes, prevents replicas from trying to failover its
      # master during master failures. However the master can still perform a
      # manual failover, if forced to do so.
      #
      # This is useful in different scenarios, especially in the case of multiple
      # data center operations, where we want one side to never be promoted if not
      # in the case of a total DC failure.
      #
      # cluster-replica-no-failover no

      # In order to setup your cluster make sure to read the documentation
      # available at http://redis.io web site.

      ########################## CLUSTER DOCKER/NAT support ########################

      # In certain deployments, Redis Cluster nodes address discovery fails, because
      # addresses are NAT-ted or because ports are forwarded (the typical case is
      # Docker and other containers).
      #
      # In order to make Redis Cluster working in such environments, a static
      # configuration where each node knows its public address is needed. The
      # following two options are used for this scope, and are:
      #
      # * cluster-announce-ip
      # * cluster-announce-port
      # * cluster-announce-bus-port
      #
      # Each instruct the node about its address, client port, and cluster message
      # bus port. The information is then published in the header of the bus packets
      # so that other nodes will be able to correctly map the address of the node
      # publishing the information.
      #
      # If the above options are not used, the normal Redis Cluster auto-detection
      # will be used instead.
      #
      # Note that when remapped, the bus port may not be at the fixed offset of
      # clients port + 10000, so you can specify any port and bus-port depending
      # on how they get remapped. If the bus-port is not set, a fixed offset of
      # 10000 will be used as usually.
      #
      # Example:
      #
      # cluster-announce-ip 10.1.1.5
      # cluster-announce-port 6379
      # cluster-announce-bus-port 6380

      ################################## SLOW LOG ###################################

      # The Redis Slow Log is a system to log queries that exceeded a specified
      # execution time. The execution time does not include the I/O operations
      # like talking with the client, sending the reply and so forth,
      # but just the time needed to actually execute the command (this is the only
      # stage of command execution where the thread is blocked and can not serve
      # other requests in the meantime).
      #
      # You can configure the slow log with two parameters: one tells Redis
      # what is the execution time, in microseconds, to exceed in order for the
      # command to get logged, and the other parameter is the length of the
      # slow log. When a new command is logged the oldest one is removed from the
      # queue of logged commands.

      # The following time is expressed in microseconds, so 1000000 is equivalent
      # to one second. Note that a negative number disables the slow log, while
      # a value of zero forces the logging of every command.
      slowlog-log-slower-than 10000

      ################################ LATENCY MONITOR ##############################

      # The Redis latency monitoring subsystem samples different operations
      # at runtime in order to collect data related to possible sources of
      # latency of a Redis instance.
      #
      # Via the LATENCY command this information is available to the user that can
      # print graphs and obtain reports.
      #
      # The system only logs operations that were performed in a time equal or
      # greater than the amount of milliseconds specified via the
      # latency-monitor-threshold configuration directive. When its value is set
      # to zero, the latency monitor is turned off.
      #
      # By default latency monitoring is disabled since it is mostly not needed
      # if you don't have latency issues, and collecting data has a performance
      # impact, that while very small, can be measured under big load. Latency
      # monitoring can easily be enabled at runtime using the command
      # "CONFIG SET latency-monitor-threshold <milliseconds>" if needed.

      ############################# EVENT NOTIFICATION ##############################

      # Redis can notify Pub/Sub clients about events happening in the key space.
      # This feature is documented at http://redis.io/topics/notifications
      #
      # For instance if keyspace events notification is enabled, and a client
      # performs a DEL operation on key "foo" stored in the Database 0, two
      # messages will be published via Pub/Sub:
      #
      # PUBLISH __keyspace@0__:foo del
      # PUBLISH __keyevent@0__:del foo
      #
      # It is possible to select the events that Redis will notify among a set
      # of classes. Every class is identified by a single character:
      #
      # K Keyspace events, published with __keyspace@<db>__ prefix.
      # E Keyevent events, published with __keyevent@<db>__ prefix.
      # g Generic commands (non-type specific) like DEL, EXPIRE, RENAME, ...
      # $ String commands
      # l List commands
      # s Set commands
      # h Hash commands
      # z Sorted set commands
      # x Expired events (events generated every time a key expires)
      # e Evicted events (events generated when a key is evicted for maxmemory)
      # A Alias for g$lshzxe, so that the "AKE" string means all the events.
      #
      # The "notify-keyspace-events" takes as argument a string that is composed
      # of zero or multiple characters. The empty string means that notifications
      # are disabled.
      #
      # Example: to enable list and generic events, from the point of view of the
      # event name, use:
      #
      # notify-keyspace-events Elg
      #
      # Example 2: to get the stream of the expired keys subscribing to channel
      # name __keyevent@0__:expired use:
      #
      # notify-keyspace-events Ex
      #
      # By default all notifications are disabled because most users don't need
      # this feature and the feature has some overhead. Note that if you don't
      # specify at least one of K or E, no events will be delivered.

      # By default "hz" is set to 10. Raising the value will use more CPU when
      # Redis is idle, but at the same time will make Redis more responsive when
      # there are many keys expiring at the same time, and timeouts may be
      # handled with more precision.
      #
      # The range is between 1 and 500, however a value over 100 is usually not

      # Normally it is useful to have an HZ value which is proportional to the

      # When dynamic HZ is enabled, the actual configured HZ will be used as
      # as a baseline, but multiples of the configured HZ value will be actually

      # Redis LFU eviction (see maxmemory setting) can be tuned. However it is a good
      # idea to start with the default settings and only change them after investigating
      # how to improve the performances and how the keys LFU change over time, which
      # is possible to inspect via the OBJECT FREQ command.
      #
      # There are two tunable parameters in the Redis LFU implementation: the
      # counter logarithm factor and the counter decay time. It is important to
      # understand what the two parameters mean before changing them.
      #
      # The LFU counter is just 8 bits per key, it's maximum value is 255, so Redis
      # uses a probabilistic increment with logarithmic behavior. Given the value
      # of the old counter, when a key is accessed, the counter is incremented in
      # this way:
      #
      # 1. A random number R between 0 and 1 is extracted.
      # 2. A probability P is calculated as 1/(old_value*lfu_log_factor+1).
      # 3. The counter is incremented only if R < P.
      #
      # The default lfu-log-factor is 10. This is a table of how the frequency
      # counter changes with a different number of accesses with different
      # logarithmic factors:
      #
      # +--------+------------+------------+------------+------------+------------+
      # | factor | 100 hits | 1000 hits | 100K hits | 1M hits | 10M hits |
      # +--------+------------+------------+------------+------------+------------+
      # | 0 | 104 | 255 | 255 | 255 | 255 |
      # +--------+------------+------------+------------+------------+------------+

      #
      # NOTE 2: The counter initial value is 5 in order to give new objects a chance
      # to accumulate hits.
      #
      # The counter decay time is the time, in minutes, that must elapse in order
      # for the key counter to be divided by two (or decremented if it has a value
      # less <= 10).

      ########################### ACTIVE DEFRAGMENTATION #######################
      #
      # WARNING THIS FEATURE IS EXPERIMENTAL. However it was stress tested
      # even in production and manually tested by multiple engineers for some
      # time.
      #
      # What is active defragmentation?
      # -------------------------------
      #
      # Active (online) defragmentation allows a Redis server to compact the
      # spaces left between small allocations and deallocations of data in memory,
      # thus allowing to reclaim back memory.
      #
      # Fragmentation is a natural process that happens with every allocator (but
      # less so with Jemalloc, fortunately) and certain workloads. Normally a server
      # restart is needed in order to lower the fragmentation, or at least to flush
      # away all the data and create it again. However thanks to this feature
      # implemented by Oran Agra for Redis 4.0 this process can happen at runtime
      # in an "hot" way, while the server is running.
      #
      # Basically when the fragmentation is over a certain level (see the
      # configuration options below) Redis will start to create new copies of the
      # values in contiguous memory regions by exploiting certain specific Jemalloc
      # features (in order to understand if an allocation is causing fragmentation
      # and to allocate it in a better place), and at the same time, will release the
      # old copies of the data. This process, repeated incrementally for all the keys
      # will cause the fragmentation to drop back to normal values.
      #
      # Important things to understand:
      #
      # 1. This feature is disabled by default, and only works if you compiled Redis
      # to use the copy of Jemalloc we ship with the source code of Redis.
      # This is the default with Linux builds.
      #
      # 2. You never need to enable this feature if you don't have fragmentation
      # issues.
      #
      # 3. Once you experience fragmentation, you can enable this feature when
      # needed with the command "CONFIG SET activedefrag yes".
      #
      # The configuration parameters are able to fine tune the behavior of the
      # defragmentation process. If you are not sure about what they mean it is
      # a good idea to leave the defaults untouched.

      # Enabled active defragmentation
      # activedefrag yes

      # Minimum amount of fragmentation waste to start active defrag
      # active-defrag-ignore-bytes 100mb

      # Minimum percentage of fragmentation to start active defrag
      # active-defrag-threshold-lower 10

      # Maximum percentage of fragmentation at which we use maximum effort
      # active-defrag-threshold-upper 100

      # Minimal effort for defrag in CPU percentage
      # active-defrag-cycle-min 5

      # Maximal effort for defrag in CPU percentage
      # active-defrag-cycle-max 75

      # Maximum number of set/hash/zset/list fields that will be processed from
      # the main dictionary scan
