1. Basic Configuration

Memory Unit Representation

#1 k = & gt; 1000 bytes
# 1kb => 1024 bytes
#1 m => 1000000 bytes
#1 mb => 1024*1024 bytes
#1g => 1000000000 bytes
#1 gb => 1024*1024*1024 bytes

The Unit is case insensitive 1 GB 1 Gb 1 GB

Run in the background. yes is run in the background. no is run in the foreground. The output is output to the terminal (default)

Daemonize yes

If the daemonize parameter is yes, a pid file is generated, which is defined in the pid file.

Pidfile/usr/local/redis-master/run/redis. pid

Listening port

Port 6379

IP address bound to the listener

Bind 127.0.0.1

If you call redis locally, you can directly use the sock File

Location of the unixsocket/tmp/redis. sock // sock File

Unixsocketperm 755 // sock File Permission

If a link is idle in N seconds, disable it.

Timeout 0

If the other party is down or the intermediate network is disconnected, the TCP link will be disconnected if the client fails to receive the response from the other party within the specified time (unit: seconds ), this parameter is affected by kernel parameters. We recommend that you set this parameter to 60.

Tcp-keepalive 0

Specify the level of the Output Message

# Debug (debugging level, detailed information, large amount of information)
# Verbose (detailed information, large amount of information)
# Notice (notification, production environment Recommendation)
# Warning (error message warning)

Loglevel notice

Log output file. The default value of this key is stdout output to the terminal when the front-end is running. If the stdout of this key is run by the daemon, the log is input to/dev/null, to record logs, you must specify the logfile location for the logs.

Logfile/var/log/redis. log

Set the syslog recorded in the log.

Syslog-enabled no

ID of the specified syslog

Syslog-ident redis

Specifies the level of syslog, between LOCAL0-LOCAL7

Syslog-facility local0

Set the number of databases

Databases 16

Set the number of databases. The default database is DB 0. You can SELECT a different per-connection The DBID here is between 0 and 'databases'-1

Databases 16

2. snapshot Configuration

Rule definition for saving DB to disk (snapshot)

Format: save

Example: save 900 1 // save if at least one key value changes within 900 seconds (15 minutes)

Save 300 10 // if at least 10 key values change within 300 seconds (6 minutes), save
Save 900 1 // each entry indicates a storage check
Save 300 10
Save 60 10000

If the above snapshot (RDB) is enabled, after a storage check, the disk may be broken or the permission is faulty, and redis will still work normally.

Stop-writes-on-bgsave-error yes

Whether to use LZF to compress the string to the. rdb database. If you want to save CPU resources, you can set it to no, but the space occupied by storing the string on the disk will be large. The default value is yes.

Rdbcompression yes

Rdb File validation. If it is used to verify the file, the file format will be avoided. If it is not used to verify the file, the resource new energy in the verification process will be required during each operation. If this parameter is set to no, the verification will be skipped.

Rdbchecksum yes

File Name of the dump data

Dbfilename dump. rdb

Redis working directory, which stores the dump file to this directory and generates an additional file

Dir/usr/local/redis-master/db

3. Master/Slave Parameters
If the local server is a salve server, configure this item.

# Slaveof

Slaveof 127.0.0.1 65532

Master verification Password

Masterauth

When the slave host is disconnected from the master, if this value is yes, when the client queries the slave, the ECHO should be sent to the client. If it is the first time that the client returns a date data or the null value, if it is set to no, "SYNC with master in SS" is returned to INFO and SLAVEOF

Slave-serve-stale-data yes

Slave server read-only (default)

Slave-read-only yes

Interval (in seconds) from sending ping to master)

Repl-ping-slave-period 10

Batch Transfer I/O timeout and master data or ping response Timeout: The default value is 60 s, which must be greater than the repl-ping-slave-period value.

Repl-timeout 60

If this option is "yes", Redis uses a small number of TCP packets and less bandwidth to send data, with a latency of 40 milliseconds from the host (40 milliseconds in linux kernel). If no is used, the latency will be reduced in slave, but the traffic usage is relatively large. If multiple slave hosts are used, we recommend that you set yes

Repl-disable-tcp-nodelay no

Slave host priority. If the master host is down, a slave host will be selected as another slave host. The first priority is the master, 0 is a special level, and 0 will never become the master. The default value is 100.

Slave-priority 100
