如今，越来越多的企业开始使用Redis了。很多朋友给我发来私信，问如何才能搭建一个Redis集群。那么，今天，我就给大家带来一篇关于Redis主从配置的文章，好了，不多说了，我们直接进入主题。

一、创建相关目录

# mkdir -p /usr/local/redis/{etc,bin,var}# mkdir -p /data/logs/redis /data/dbcache

二、编译安装Redis

# tar -xvzf redis-2.4.13.tar.gz# cd redis-2.4.13# make# cd src && cp redis-server redis-cli redis-benchmark /usr/local/redis/bin# echo "vm.overcommit_memory=1" >> /etc/sysctl.conf# /sbin/sysctl -p

三、主服务器设置(192.168.1.100)

# vim /usr/local/redis/etc/redis.confdaemonize yespidfile /usr/local/redis/var/redis.pidport 6379bind 192.168.1.100unixsocket /usr/local/redis/var/redis.sockunixsocketperm 755timeout 300loglevel verboselogfile /data/logs/redis/redis.log# syslog-enabled no# syslog-ident redis# syslog-facility local0databases 16save 900 1save 300 10save 60 10000rdbcompression yesdbfilename dump.rdbdir /data/dbcache# slaveof <masterip> <masterport># masterauth <master-password># repl-ping-slave-period 10# repl-timeout 60requirepass redis123# rename-command CONFIG ""maxclients 0# maxmemory <bytes># maxmemory-policy volatile-lru# maxmemory-samples 3appendonly noappendfilename appendonly.aofappendfsync alwaysno-appendfsync-on-rewrite noauto-aof-rewrite-percentage 100auto-aof-rewrite-min-size 64mbslowlog-log-slower-than 10000slowlog-max-len 128vm-enabled novm-swap-file /data/dbcache/redis.swapvm-max-memory 0vm-page-size 32vm-pages 134217728vm-max-threads 4glueoutputbuf yeshash-max-zipmap-entries 512hash-max-zipmap-value 64list-max-ziplist-entries 512list-max-ziplist-value 64set-max-intset-entries 512zset-max-ziplist-entries 128zset-max-ziplist-value 64activerehashing yes

四、从服务器设置(192.168.1.200)

daemonize yespidfile /usr/local/redis/var/redis.pidport 6379bind 192.168.1.200unixsocket /usr/local/redis/var/redis.sockunixsocketperm 755timeout 300loglevel verboselogfile /data/logs/redis/redis.log# syslog-enabled no# syslog-ident redis# syslog-facility local0databases 16save 900 1save 300 10save 60 10000rdbcompression yesdbfilename dump.rdbdir /data/dbcache# slaveof <masterip> <masterport># masterauth <master-password># repl-ping-slave-period 10# repl-timeout 60# rename-command CONFIG ""maxclients 0# maxmemory <bytes># maxmemory-policy volatile-lru# maxmemory-samples 3appendonly noappendfilename appendonly.aofappendfsync alwaysno-appendfsync-on-rewrite noauto-aof-rewrite-percentage 100auto-aof-rewrite-min-size 64mbslowlog-log-slower-than 10000slowlog-max-len 128vm-enabled novm-swap-file /data/dbcache/redis.swapvm-max-memory 0vm-page-size 32vm-pages 134217728vm-max-threads 4glueoutputbuf yeshash-max-zipmap-entries 512hash-max-zipmap-value 64list-max-ziplist-entries 512list-max-ziplist-value 64set-max-intset-entries 512zset-max-ziplist-entries 128zset-max-ziplist-value 64activerehashing yesslave-serve-stale-data yesslaveof 192.168.1.100 6379masterauth redis123

五、启动服务

# /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf

主服务器上执行：

# /usr/local/redis/bin/redis-cli -h 192.168.1.100 -a redis123 set test 123456

从服务器上执行：

# /usr/local/redis/bin/redis-cli -h 192.168.1.200 get test

六、启动脚本

#!/bin/sh## redis - this script starts and stops the redis-server daemon## chkconfig:   - 85 15# description:  Redis is a persistent key-value database# processname: redis-server# config:      /usr/local/redis/etc/redis.conf# pidfile:     /usr/local/redis/var/redis.pid# Check that networking is up.                                              [ "$NETWORKING" = "no" ] && exit 0                                              redis="/usr/local/redis/bin/redis-server"prog=$(basename $redis)REDIS_CONF_FILE="/usr/local/redis/etc/redis.conf"lockfile="/var/lock/subsys/redis"                                              start() {    [ -x $redis ] || exit 5    [ -f $REDIS_CONF_FILE ] || exit 6                                                     echo -n $"Starting $prog: "    $redis $REDIS_CONF_FILE    retval=$?    echo    [ $retval -eq 0 ] && touch $lockfile                                                     return $retval}                                              stop() {    echo -n $"Stopping $prog: "    /sbin/killproc $prog -QUIT                                                     retval=$?    echo    [ $retval -eq 0 ] && rm -f $lockfile                                                     return $retval}                                              restart() {    stop    sleep 1    start}                                              reload() {    echo -n $"Reloading $prog: "    /sbin/killproc $redis -HUP                                                     RETVAL=$?    echo                                                     return $retval}                                              case "$1" instart)    $1    ;;                                                 stop)    $1    ;;                                                 restart)    $1    ;;                                                 reload)    $1    ;;                                                 *)    echo $"Usage: $0 {start|stop|restart|reload}"    exit 2esac

七、启动服务

# chmod 700 /etc/init.d/redis# chkconfig --add redis# service redis start

八、测试是否已启动

# /usr/local/redis/bin/redis-cli ping

九、性能测试

# /usr/local/redis/bin/redis-benchmark

十、关闭服务

# /usr/local/redis/bin/redis-cli -p 6379 shutdown

十一、强制刷新数据到磁盘【Redis默认是异步写入磁盘的】

# /usr/local/redis/bin/redis-cli -p 6379 save
