# Redis configuration file example  
  
# 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  
  
# When run as a daemon, Redis write a pid file in /var/run/redis.pid by default.  
# You can specify a custom pid file location here.  
pidfile /var/run/redis.pid  
  
# Accept connections on the specified port, default is 6379  
port 6379  
  
# If you want you can bind a single interface, if the bind option is not  
# specified all the interfaces will listen for connections.  
#  
# bind 127.0.0.1  
  
# Close the connection after a client is idle for N seconds (0 to disable)  
timeout 300  
  
# Set server verbosity to 'debug'  
# it can be one of:  
# debug (a lot of information, useful for development/testing)  
# notice (moderately verbose, what you want in production probably)  
# warning (only very important / critical messages are logged)  
loglevel debug  
  
# Specify the log file name. Also 'stdout' can be used to force  
# the demon 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 stdout  
  
# 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  
  
################################ SNAPSHOTTING  #################################  
#  
# Save the DB on disk:  
#  
#   save <seconds> <changes>  
#  
#   Will save the DB if both the given number of seconds and the given  
#   number of write operations against the DB occurred.  
#  
#   In the example below the behaviour will be to save:  
#   after 900 sec (15 min) if at least 1 key changed  
#   after 300 sec (5 min) if at least 10 keys changed  
#   after 60 sec if at least 10000 keys changed  
save 900 1  
save 300 10  
save 60 10000  
  
# Compress string objects using LZF when dump .rdb databases?  
# For default that's set to 'yes' as it's almost always a win.  
# If you want to save some CPU in the saving child set it to 'no' but  
# the dataset will likely be bigger if you have compressible values or keys.  
rdbcompression yes  
  
# The filename where to dump the DB  
dbfilename dump.rdb  
  
# For default save/load DB in/from the working directory  
# Note that you must specify a directory not a file name.  
dir ./  
  
################################# REPLICATION #################################  
  
# Master-Slave replication. Use slaveof to make a Redis instance a copy of  
# another Redis server. Note that the configuration is local to the slave  
# so for example it is possible to configure the slave to save the DB with a  
# different interval, or to listen to another port, and so on.  
#  
# slaveof <masterip> <masterport>  
  
# If the master is password protected (using the "requirepass" configuration  
# directive below) it is possible to tell the slave to authenticate before  
# starting the replication synchronization process, otherwise the master will  
# refuse the slave request.  
#  
# masterauth <master-password>  
  
################################## SECURITY ###################################  
  
# Require clients to issue AUTH <PASSWORD> before processing any other  
# commands.  This might be useful in environments in which you do not trust  
# others with access to the host running redis-server.  
#  
# This should stay commented out for backward compatibility and because most  
# people do not need auth (e.g. they run their own servers).  
#  
# requirepass foobared  
  
################################### LIMITS ####################################  
  
# Set the max number of connected clients at the same time. By default there  
# is no limit, and it's up to the number of file descriptors the Redis process  
# is able to open. The special value '0' means no limts.  
# Once the limit is reached Redis will close all the new connections sending  
# an error 'max number of clients reached'.  
#  
# maxclients 128  
  
# Don't use more memory than the specified amount of bytes.  
# When the memory limit is reached Redis will try to remove keys with an  
# EXPIRE set. It will try to start freeing keys that are going to expire  
# in little time and preserve keys with a longer time to live.  
# Redis will also try to remove objects from free lists if possible.  
#  
# If all this fails, Redis will start to reply with errors to commands  
# that will use more memory, like SET, LPUSH, and so on, and will continue  
# to reply to most read-only commands like GET.  
#  
# WARNING: maxmemory can be a good idea mainly if you want to use Redis as a  
# 'state' server or cache, not as a real DB. When Redis is used as a real  
# database the memory usage will grow over the weeks, it will be obvious if  
# it is going to use too much memory in the long run, and you'll have the time  
# to upgrade. With maxmemory after the limit is reached you'll start to get  
# errors for write operations, and this may even lead to DB inconsistency.  
#  
# maxmemory <bytes>  
  
############################## APPEND ONLY MODE ###############################  
  
# By default Redis asynchronously dumps the dataset on disk. If you can live  
# with the idea that the latest records will be lost if something like a crash  
# happens this is the preferred way to run Redis. If instead you care a lot  
# about your data and don't want to that a single record can get lost you should  
# enable the append only mode: when this mode is enabled Redis will append  
# every write operation received in the file appendonly.log. This file will  
# be read on startup in order to rebuild the full dataset in memory.  
#  
# Note that you can have both the async dumps and the append only file if you  
# like (you have to comment the "save" statements above to disable the dumps).  
# Still if append only mode is enabled Redis will load the data from the  
# log file at startup ignoring the dump.rdb file.  
#  
# The name of the append only file is "appendonly.log"  
#  
# IMPORTANT: Check the BGREWRITEAOF to check how to rewrite the append  
# log file in background when it gets too big.  
  
appendonly yes  
  
# The fsync() call tells the Operating System to actually write data on disk  
# instead to wait 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 if one second passed since the last fsync. Compromise.  
#  
# The default is "always" that's the safer of the options. It's up to you to  
# understand if you can relax this to "everysec" that will fsync every second  
# or to "no" that will let the operating system flush the output buffer when  
# it want, for better performances (but if you can live with the idea of  
# some data loss consider the default persistence mode that's snapshotting).  
  
appendfsync always  
# appendfsync everysec  
# appendfsync no  
  
############################### ADVANCED CONFIG ###############################  
  
# Glue small output buffers together in order to send small replies in a  
# single TCP packet. Uses a bit more CPU but most of the times it is a win  
# in terms of number of queries per second. Use 'yes' if unsure.  
glueoutputbuf yes  
  
# Use object sharing. Can save a lot of memory if you have many common  
# string in your dataset, but performs lookups against the shared objects  
# pool so it uses more CPU and can be a bit slower. Usually it's a good  
# idea.  
#  
# When object sharing is enabled (shareobjects yes) you can use  
# shareobjectspoolsize to control the size of the pool used in order to try  
# object sharing. A bigger pool size will lead to better sharing capabilities.  
# In general you want this value to be at least the double of the number of  
# very common strings you have in your dataset.  
#  
# WARNING: object sharing is experimental, don't enable this feature  
# in production before of Redis 1.0-stable. Still please try this feature in  
# your development environment so that we can test it better.  
# shareobjects no  
# shareobjectspoolsize 1024
