  # By default protected mode is enabled. You should disable it only if

  #
  # In high requests-per-second environments you need an high backlog in order
  # to avoid slow clients connections issues. Note that the Linux kernel
  # will silently truncate it to the value of /proc/sys/net/core/somaxconn so
  # make sure to raise both the value of somaxconn and tcp_max_syn_backlog
  # in order to get the desired effect.

  ################################# GENERAL #####################################
   
   
  # By default Redis does not run as a daemon. Use 'yes' if you need it.
  # Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
  #
  daemonize no
   
   
  # If you run Redis from upstart or systemd, Redis can interact with your
  # supervision tree. Options:
  # supervised no - no supervision interaction
  # supervised upstart - signal upstart by putting Redis into SIGSTOP mode
  # supervised systemd - signal systemd by writing READY=1 to $NOTIFY_SOCKET
  # supervised auto - detect upstart or systemd method based on
  # UPSTART_JOB or NOTIFY_SOCKET environment variables
  # Note: these supervision methods only signal "process is ready."
  # They do not enable continuous liveness pings back to your supervisor.
  #
  supervised no
   
   
  # If a pid file is specified, Redis writes it where specified at startup
  # and removes it at exit.
  #
  # When the server runs non daemonized, no pid file is created if none is
  # specified in the configuration. When the server is daemonized, the pid file
  # is used even if not specified, defaulting to "/var/run/redis.pid".
  #
  # Creating a pid file is best effort: if Redis is not able to create it
  # nothing bad happens, the server will start and run normally.
  #
  pidfile /var/run/redis_6380.pid
   
   
  # Specify the server verbosity level.
  # This can be one of:
  # debug (a lot of information, useful for development/testing)
  # verbose (many rarely useful info, but not a mess like the debug level)
  # notice (moderately verbose, what you want in production probably)
  # warning (only very important / critical messages are logged)
  #
  loglevel notice
   
   
  # Specify the log file name. Also the empty string can be used to force
  # Redis to log on the standard output. Note that if you use standard
  # output for logging but daemonize, logs will be sent to /dev/null
  #
  logfile ""
   
   
  # Set the number of databases. The default database is DB 0, you can select
  # a different one on a per-connection basis using SELECT <dbid> where
  # dbid is a number between 0 and 'databases'-1
  #
  databases 16
   
   
  # However it is possible to force the pre-4.0 behavior and always show a
  # ASCII art logo in startup logs by setting the following option to yes.
  #
  always-show-logo yes
   
   
  ################################ SNAPSHOTTING ################################
   
  #
  # Save the DB on disk:
  #
  # 这里是用来配置触发 Redis的 RDB 持久化条件,也就是什么时候将内存中的数据保存到硬盘.
  # 比如“save m n”.表示m秒内数据集存在n次修改时,自动触发bgsave
  # 当然如果你只是用Redis的缓存功能,不需要持久化:
  # save ""
  #
  save 900 1
  save 300 10
  save 60 10000
   
   
  # 默认值为yes.当启用了RDB且最后一次后台保存数据失败,Redis是否停止接收数据.
  # 这会让用户意识到数据没有正确持久化到磁盘上,否则没有人会注意到灾难（disaster）发生了.
  # 如果Redis重启了,那么又可以重新开始接收数据了
  #
  stop-writes-on-bgsave-error yes
  # 建议设置为 no 否则程序可能就报这个错.<br># MISCONF Redis is configured to save RDB snapshots,<br># but it is currently not able to persist on disk. <br># Commands that may modify the data set are disabled, <br># because this instance is configured to report errors <br># during writes if RDB snapshotting fails <br># (stop-writes-on-bgsave-error option). <br># Please check the Redis logs for details about the RDB error.
   
  # 默认值是yes.对于存储到磁盘中的快照,可以设置是否进行压缩存储.
  # 如果是的话,redis会采用LZF算法进行压缩.
  # 如果你不想消耗CPU来进行压缩的话,可以设置为关闭此功能,但是存储在磁盘上的快照会比较大.
  #
  rdbcompression yes
   
   
  # 默认值是yes.在存储快照后,我们还可以让redis使用CRC64算法来进行数据校验,
  # 但是这样做会增加大约10%的性能消耗,如果希望获取到最大的性能提升,可以关闭此功能.
  #
  rdbchecksum yes
   
   
  # 设置快照的文件名,默认是 dump.rdb
  #
  dbfilename dump.rdb
   
   
  # 设置快照文件的存放路径,这个配置项一定是个目录,而不能是文件名.默认是和当前配置文件保存在同一目录.
  #
  dir ./
   
   
  ################################# REPLICATION #################################
   
  # When a slave loses its connection with the master, or when the replication
  # is still in progress, the slave can act in two different ways:
  #
  # 1) if slave-serve-stale-data is set to 'yes' (the default) the slave 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 slave-serve-stale-data is set to 'no' the slave will reply with
  # an error "SYNC with master in progress" to all the kind of commands
  # but to INFO and SLAVEOF.
  #
  slave-serve-stale-data yes
   
   
  # Note: read only slaves 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 slave 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 slaves using 'rename-command' to shadow all the
  # administrative / dangerous commands.
  #
  slave-read-only yes
   
   
  # With slow disks and fast (large bandwidth) networks, diskless replication
  # works better.
  #
  repl-diskless-sync no
   
   
  # 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
   
   
  # By default we optimize for low latency, but in very high traffic conditions
  # or when the master and slaves are many hops away, turning this to "yes" may
  # be a good idea.
  #
  repl-disable-tcp-nodelay no
   
   
  # By default the priority is 100.
  #
  slave-priority 100
   
   
  ################################## SECURITY ###################################
   
  # Warning: since Redis is pretty fast an outside user can try up to
  # 150k passwords per second against a good box. This means that you should
  # use a very strong password otherwise it will be very easy to break.
  #
  requirepass xxx
   
   
  ############################# LAZY FREEING ####################################
   
   
  # 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
  slave-lazy-flush no
   
   
  ############################## APPEND ONLY MODE ###############################
   
   
  # 默认值为no,也就是说redis 默认使用的是rdb方式持久化,
  # 如果想要开启 AOF 持久化方式,需要将 appendonly 修改为 yes.
  #
  appendonly no
   
  # aof文件名,默认是"appendonly.aof"
  #
  appendfilename "appendonly.aof"
   
   
  # aof持久化策略的配置；
  #
  #　　　　　　no表示不执行fsync,由操作系统保证数据同步到磁盘,速度最快,但是不太安全；
  #
  #　　　　　　always表示每次写入都执行fsync,以保证数据同步到磁盘,效率很低；
  #
  #　　　　　　everysec表示每秒执行一次fsync,可能会导致丢失这1s数据.通常选择 everysec ,兼顾安全性和效率
  #
  appendfsync everysec
   
   
  # 在aof重写或者写入rdb文件的时候,会执行大量IO,此时对于everysec和always的aof模式来说,
  # 执行fsync会造成阻塞过长时间,no-appendfsync-on-rewrite字段设置为默认设置为no.
  # 如果对延迟要求很高的应用,这个字段可以设置为yes,否则还是设置为no,
  # 这样对持久化特性来说这是更安全的选择.
  # 设置为yes表示rewrite期间对新写操作不fsync,暂时存在内存中,等rewrite完成后再写入,默认为no,建议yes.
  # Linux的默认fsync策略是30秒.可能丢失30秒数据.默认值为no.
  #
  no-appendfsync-on-rewrite no
   
   
  # 默认值为100.aof自动重写配置,当目前aof文件大小超过上一次重写的aof文件大小的百分之多少进行重写,
  # 即当aof文件增长到一定大小的时候,Redis能够调用bgrewriteaof对日志文件进行重写.
  # 当前AOF文件大小是上次日志重写得到AOF文件大小的二倍（设置为100）时,自动启动新的日志重写过程.
  #
  auto-aof-rewrite-percentage 100
   
   
  # 设置允许重写的最小aof文件大小,避免了达到约定百分比但尺寸仍然很小的情况还要重写.
  #
  auto-aof-rewrite-min-size 64mb
   
   
  # aof文件可能在尾部是不完整的,当redis启动的时候,aof文件的数据被载入内存.
  # 重启可能发生在redis所在的主机操作系统宕机后,尤其在ext4文件系统没有加上data=ordered选项,
  # 出现这种现象 redis宕机或者异常终止不会造成尾部不完整现象,可以选择让redis退出,
  # 或者导入尽可能多的数据.如果选择的是yes,当截断的aof文件被导入的时候,
  # 会自动发布一个log给客户端然后load.如果是no,用户必须手动redis-check-aof修复AOF文件才可以.
  # 默认值为 yes
  #
  aof-load-truncated yes
   
   
  # This is currently turned off by default in order to avoid the surprise
  # of a format change, but will at some point be used as the default.
  #
  aof-use-rdb-preamble no
   
   
  # Set it to 0 or a negative value for unlimited execution without warnings.
  #
  lua-time-limit 5000
   
   
  ################################## SLOW LOG ###################################
   
   
  # 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
   
   
  # There is no limit to this length. Just be aware that it will consume memory.
  # You can reclaim memory used by the slow log with SLOWLOG RESET.
  #
  slowlog-max-len 128
   
   
  ################################ LATENCY MONITOR ##############################
   
   
  # 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.
  #
  latency-monitor-threshold 0
   
   
  ############################# EVENT NOTIFICATION ##############################
   
  # 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.
  #
  notify-keyspace-events ""
   
   
  ############################### ADVANCED CONFIG ###############################
   
   
  # Hashes are encoded using a memory efficient data structure when they have a
  # small number of entries, and the biggest entry does not exceed a given
  # threshold. These thresholds can be configured using the following directives.
  #
  hash-max-ziplist-entries 512
  hash-max-ziplist-value 64
   
   
  # Positive numbers mean store up to _exactly_ that number of elements
  # per list node.
  # The highest performing option is usually -2 (8 Kb size) or -1 (4 Kb size),
  # but if your use case is unique, adjust the settings as necessary.
  #
  list-max-ziplist-size -2
   
   
  # 3: [head]->[next]->[next]->node->node->...->node->[prev]->[prev]->[tail]
  # etc.
  #
  list-compress-depth 0
   
   
  # Sets have a special encoding in just one case: when a set is composed
  # of just strings that happen to be integers in radix 10 in the range
  # of 64 bit signed integers.
  # The following configuration setting sets the limit in the size of the
  # set in order to use this special memory saving encoding.
  #
  set-max-intset-entries 512
   
   
  # Similarly to hashes and lists, sorted sets are also specially encoded in
  # order to save a lot of space. This encoding is only used when the length and
  # elements of a sorted set are below the following limits:
  #
  zset-max-ziplist-entries 128
  zset-max-ziplist-value 64
   
   
  # The suggested value is ~ 3000 in order to have the benefits of
  # the space efficient encoding without slowing down too much PFADD,
  # which is O(N) with the sparse encoding. The value can be raised to
  # ~ 10000 when CPU is not a concern, but space is, and the data set is
  # composed of many HyperLogLogs with cardinality in the 0 - 15000 range.
  #
  hll-sparse-max-bytes 3000
   
   
  # use "activerehashing yes" if you don't have such hard requirements but
  # want to free memory asap when possible.
  #
  activerehashing yes
   
   
  # Both the hard or the soft limit can be disabled by setting them to zero.

  client-output-buffer-limit pubsub 32mb 8mb 60
   
   
  # The range is between 1 and 500, however a value over 100 is usually not
  # a good idea. Most users should use the default of 10 and raise this up to
  # 100 only in environments where very low latency is required.
  #
  hz 10
   
   
  # When a child rewrites the AOF file, if the following option is enabled
  # the file will be fsync-ed every 32 MB of data generated. This is useful
  # in order to commit the file to the disk more incrementally and avoid
  # big latency spikes.
