Detailed description of the Redis configuration file redis.conf

# Redis configuration file

# When you need to configure the memory size in the configuration, you can use similar formats such as 1k, 5GB, 4M, which are converted as follows (case-insensitive)
#
# 1k =>
1000 bytes
# 1kb => 1024 bytes
# 1m => 1000000 bytes
# 1MB =>
1024*1024 bytes
# 1g => 1000000000 bytes
# 1GB => 1024*1024*1024
bytes
#
# memory configuration case is the same. For example 1GB 1Gb 1GB 1gB

# Daemonize No by default, Redis does not run in the background, and if you need to run in the background, change the value of the item to Yes
Daemonize
Yes

# when Redis is running in the background, Redis the default will put the PID file in/var/run/redis.pid, you can configure to other addresses.
#
When running multiple Redis services, you need to specify different PID files and ports
Pidfile/var/run/redis.pid

# Specifies the port on which Redis is running, by default 6379
Port 6379

# Specifies that Redis only receive requests from this IP address, and if not set, all requests will be processed.
# It is best to set this item in a production environment
# bind
127.0.0.1

# Specify the path for the UNIX socket, that'll be used to listen for
#
Incoming connections. There is no default, so Redis would not listen
# on a
The UNIX socket is not specified.
#
# Unixsocket/tmp/redis.sock
#
Unixsocketperm 755

# Sets the timeout in seconds for client connections. When the client does not issue any instructions during this time, close the connection
# 0 is to turn off this setting
Timeout
0

# Specify Logging Level
# Redis supports a total of four levels: Debug, verbose, notice, warning, default to verbose
#
Debug records a lot of information for development and testing
# Varbose Useful information, unlike debug will record so much
#
Notice common verbose, often used in production environments
# warning only very important or serious information will be logged to the log
LogLevel
Debug

# Configure log file address
# The default value is stdout, standard output, if the background mode will be output to/dev/null
#logfile
StdOut
Logfile/var/log/redis/redis.log

# To enable logging to the system logger, just set ' syslog-enabled ' to
Yes
# and optionally update the other syslog parameters to suit your
Needs.
# syslog-enabled No

# Specify the syslog identity.
# syslog-ident Redis

# Specify the syslog facility. Must be USER or between local0-local7.
#
Syslog-facility local0

# Number of available databases
# The default value is 16, the default database is 0, and the database ranges between 0-(database-1)
Databases 16

################################ Snapshots
#################################
#
# Save data to disk in the following format:
#
# Save
<seconds> <changes>
#
#
Indicates how many update operations have been done over a long period of time, synchronizing the data to the data file RDB.
# The equivalent of a conditional trigger grab snapshot, which can be combined with multiple conditions
#
#
For example, the settings in the default configuration file set three criteria
#
# Save 900 1 900 seconds at least 1 keys have been changed
# Save 300
At least 300 keys have been changed in 10 300 seconds.
# Save 60 10000 60 seconds at least 10,000 keys have been changed
