为大家介绍redis主从配置的具体方法，从安装到配置，到启动脚本，很全面的。
是一篇不错的有关redsi主从配置的文章。

1，创建目录

复制代码代码示例:

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

2，编译安装redis

复制代码代码示例:

  # 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

3，主服务器设置【192.168.1.100】：

复制代码代码示例:

  # vim /usr/local/redis/etc/redis.conf
 
 daemonize yes
 
 pidfile /usr/local/redis/var/redis.pid
 
 port 6379
 
 bind 192.168.1.100

4，从服务器设置【192.168.1.200】:

复制代码代码示例:

 pidfile /usr/local/redis/var/redis.pid
 
 port 6379
 
 bind 192.168.1.200
 
 unixsocket /usr/local/redis/var/redis.sock
 
 unixsocketperm 755
 
 timeout 300
 
 loglevel verbose
 
 logfile /data/logs/redis/redis.log
 
 # syslog-enabled no
 
 # syslog-ident redis
 
 # syslog-facility local0
 
 databases 16
 
 save 900 1
 
 save 300 10
 
 save 60 10000
 
 rdbcompression yes
 
 dbfilename dump.rdb
 
 dir /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 3
 
 appendonly no
 
 appendfilename appendonly.aof
 
 appendfsync always
 
 no-appendfsync-on-rewrite no
 
 auto-aof-rewrite-percentage 100
 
 auto-aof-rewrite-min-size 64mb
 
 slowlog-log-slower-than 10000
 
 slowlog-max-len 128
 
 vm-enabled no
 
 vm-swap-file /data/dbcache/redis.swap
 
 vm-max-memory 0
 
 vm-page-size 32
 
 vm-pages 134217728
 
 vm-max-threads 4
 
 glueoutputbuf yes
 
 hash-max-zipmap-entries 512
 
 hash-max-zipmap-value 64
 
 list-max-ziplist-entries 512
 
 list-max-ziplist-value 64
 
 set-max-intset-entries 512
 
 zset-max-ziplist-entries 128
 
 zset-max-ziplist-value 64
 
 activerehashing yes
 
 slave-serve-stale-data yes
 
 slaveof 192.168.1.100 6379
 
 masterauth redis123

测试：
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

6，启动脚本

复制代码代码示例:

# vim /etc/init.d/redis
#!/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
}

case "$1" in
start)
    $1
    ;;
stop)
    $1
    ;;
restart)
    $1
    ;;
reload)
    $1
    ;;
*)
    echo $"Usage: $0 {start|stop|restart|reload}"
    exit 2
esac

7，启动服务

复制代码代码示例:

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

测试是否已启动
# /usr/local/redis/bin/redis-cli ping
性能测试
# /usr/local/redis/bin/redis-benchmark
关闭服务
# /usr/local/redis/bin/redis-cli -p 6379 shutdown
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 -p6379 save

8，phpredis扩展安装

复制代码代码示例:

# svn checkout http://phpredis.googlecode.com/svn/trunk/phpredis-read-only
# /usr/local/php/bin/ phpize
# ./configure--with-php-config=/usr/local/php/bin/php-config
# make
# make install
