|
# 1k => 1000 bytes

# 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>
|
||||||
|
|
||||||
|
# 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# still reply to client requests, possibly with out of date data, or the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
|
||||||
|
|
||||||
|
# You can configure a slave instance to accept writes or not. Writing against
|
||||||
|
# a slave instance may be useful to store some ephemeral data (because data
|
||||||
|
# written on a slave will be easily deleted after resync with the master) but
|
||||||
|
# may also cause problems if clients are writing to it because of a
|
||||||
|
# misconfiguration.

#
|

|

# 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

# This option is usually useful when using Redis as an LRU cache, or to set
|
||||||
|
# a hard memory limit for an instance (using the 'noeviction' policy).
|
||||||
|
#
|
||||||
|
# WARNING: If you have slaves attached to an instance with maxmemory on,
|
||||||
|
# the size of the output buffers needed to feed the slaves 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 slaves 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 slaves attached it is suggested that you set a lower
|
||||||
|
# limit for maxmemory so that there is some free RAM on the system for slave
|
||||||
|
# output buffers (but this is not needed if the policy is 'noeviction').

# MAXMEMORY POLICY: how Redis will select what to remove when maxmemory
|
||||||
|
# is reached. You can select among five behaviors:
|
||||||
|
#
|
||||||
|
# volatile-lru -> remove the key with an expire set using an LRU algorithm
|
||||||
|
# allkeys-lru -> remove any key accordingly to the LRU algorithm
|
||||||
|
# volatile-random -> remove a random key 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 expire at all, just return an error on write operations
|
||||||
|
#
|
||||||
|
# Note: with any of the above policies, Redis will return an error on write
|
||||||
|
# operations, when there are not suitable keys for eviction.
|
||||||
|
#
|
||||||
|
# At the date of writing this commands are: set setnx setex append
|
||||||
|
# incr decr rpush lpush rpushx lpushx linsert lset rpoplpush sadd
|

|
# sinter sinterstore sunion sunionstore sdiff sdiffstore zadd zincrby

|
# The default is:

|
#
|
||||||
|
# maxmemory-policy volatile-lru
|
||||||
|
|

|
# LRU and minimal TTL algorithms are not precise algorithms but approximated

############################## 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.

|
# 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.

|
# 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

# Automatic rewrite of the append only file.
|

# Redis is able to automatically rewrite the log file implicitly calling
|
||||||
|
# BGREWRITEAOF when the AOF log size grows by the specified percentage.
|
||||||
|
#
|
||||||
|
# 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.

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

|
# 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).
|
||||||
|

############################# Event notification ##############################

|
# Redis can notify Pub/Sub clients about events happening in the key space.
|
||||||
|
# This feature is documented at http://redis.io/topics/keyspace-events
|
||||||
|
#
|
||||||
|
# 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
|
||||||
|
# by zero or multiple characters. The empty string means that notifications
|
||||||
|
# are disabled at all.
|
||||||
|
#
|
||||||
|
# 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

|
# pubsub -> clients subscribed to at least one pubsub channel or pattern

# client-output-buffer-limit <class> <hard limit> <soft limit> <soft seconds>
