   3 # By default Redis does not run as a daemon. Use 'yes' if you need it.
   4 # Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
   5 daemonize no

   7 # When run as a daemon, Redis write a pid file in /var/run/redis.pid by default.
   8 # You can specify a custom pid file location here.

  11 # Accept connections on the specified port, default is 6379

  14 # If you want you can bind a single interface, if the bind option is not
  15 # specified all the interfaces will listen for connections.

  22 # Save the DB on disk:
  23 #
  24 #   save <seconds> <changes>
  25 #
  26 #   Will save the DB if both the given number of seconds and the given
  27 #   number of write operations against the DB occurred.
  28 #
  29 #   In the example below the behaviour will be to save:
  30 #   after 900 sec (15 min) if at least 1 key changed
  31 #   after 300 sec (5 min) if at least 10 keys changed
  32 #   after 60 sec if at least 10000 keys changed

  51 # Specify the log file name. Also 'stdout' can be used to force
  52 # the demon to log on the standard output. Note that if you use standard
  53 # output for logging but daemonize, logs will be sent to /dev/null

  61 ################################# REPLICATION #################################
  62
  63 # Master-Slave replication. Use slaveof to make a Redis instance a copy of
  64 # another Redis server. Note that the configuration is local to the slave
  65 # so for example it is possible to configure the slave to save the DB with a
  66 # different interval, or to listen to another port, and so on.
  67
  68 # slaveof <masterip> <masterport>

  70 ################################## SECURITY ###################################
  71
  72 # Require clients to issue AUTH <PASSWORD> before processing any other
  73 # commands.  This might be useful in environments in which you do not trust
  74 # others with access to the host running redis-server.
  75 #
  76 # This should stay commented out for backward compatibility and because most
  77 # people do not need auth (e.g. they run their own servers).

  81 ################################### LIMITS ####################################
  82
  83 # Set the max number of connected clients at the same time. By default there
  84 # is no limit, and it's up to the number of file descriptors the Redis process
  85 # is able to open. The special value '0' means no limts.
  86 # Once the limit is reached Redis will close all the new connections sending
  87 # an error 'max number of clients reached'.
  88
  89 # maxclients 128
  90
  91 # Don't use more memory than the specified amount of bytes.
  92 # When the memory limit is reached Redis will try to remove keys with an
  93 # EXPIRE set. It will try to start freeing keys that are going to expire
  94 # in little time and preserve keys with a longer time to live.
  95 # Redis will also try to remove objects from free lists if possible.
  96 #
  97 # If all this fails, Redis will start to reply with errors to commands
  98 # that will use more memory, like SET, LPUSH, and so on, and will continue
  99 # to reply to most read-only commands like GET.
 100 #
 101 # WARNING: maxmemory can be a good idea mainly if you want to use Redis as a
 102 # 'state' server or cache, not as a real DB. When Redis is used as a real
 103 # database the memory usage will grow over the weeks, it will be obvious if
 104 # it is going to use too much memory in the long run, and you'll have the time
 105 # to upgrade. With maxmemory after the limit is reached you'll start to get
 106 # errors for write operations, and this may even lead to DB inconsistency.

 112 # Glue small output buffers together in order to send small replies in a
 113 # single TCP packet. Uses a bit more CPU but most of the times it is a win
 114 # in terms of number of queries per second. Use 'yes' if unsure.
 115 glueoutputbuf yes
 116
 117 # Use object sharing. Can save a lot of memory if you have many common
 118 # string in your dataset, but performs lookups against the shared objects
 119 # pool so it uses more CPU and can be a bit slower. Usually it's a good
 120 # idea.
 121 #
 122 # When object sharing is enabled (shareobjects yes) you can use
 123 # shareobjectspoolsize to control the size of the pool used in order to try
 124 # object sharing. A bigger pool size will lead to better sharing capabilities.
 125 # In general you want this value to be at least the double of the number of
 126 # very common strings you have in your dataset.
 127 #
 128 # WARNING: object sharing is experimental, don't enable this feature
 129 # in production before of Redis 1.0-stable. Still please try this feature in
 130 # your development environment so that we can test it better.
