Linux系统下的redis的主从配置方法非常简单，下面给大家分享一下redis的主从配置方法具体的操作步骤
环境介绍：
OS：oracle linux 5.6
redis:redis-2.6.8
master rac1 192.168.2.101
slave rac2 192.168.2.102
下载地址：
http://redis.googlecode.com/files/redis-2.6.8.tar.gz
安装配置主从redis
1. 主节点配置
[root@rac1 opt] tar zxvf redis-2.6.8.tar.gz
[root@rac1 opt] cd redis-2.6.8
[root@rac1 redis-2.6.8]# make
[root@rac1 redis-2.6.8]# cp src/redis-server /usr/local/bin/
[root@rac1 redis-2.6.8]# cp redis.conf /etc/redis_master.conf
[root@rac1 redis-2.6.8]# cat /etc/redis_master.conf
# If port 0 is specified Redis will not listen on a TCP socket.
port 6379 #此端口是redis默认的，可以不改
复制软件到从节点
[root@rac1 opt]# scp -r redis-2.6.8 rac2:/opt
2. 从节点配置
[root@rac2 redis-2.6.8]# cp src/redis-server /usr/local/bin/
[root@rac2 redis-2.6.8]# cp redis.conf /etc/redis_slave.conf
# If port 0 is specified Redis will not listen on a TCP socket.
port 6389 #修改为slave节点的自定义端口
# slaveof masterip> masterport>
slaveof 192.168.2.101 6379
此步最关键，添加上master的IP或主机及端口号
3. 启动redis服务
启动master节点
[root@rac1 ~]# redis-server /etc/redis_master.conf > redis_master.log 2>1
可以使命令在后台的执行，不影响屏幕使用。

4. 验证主从复制
master节点数据输入
[root@rac1 ~]# telnet 192.168.2.101 6379
Trying 192.168.2.101...
Connected to rac1.localdomain (192.168.2.101).
Escape character is '^]'.
rpush data 1

rpush data 1
:2
lrange data 0 -1

slave节点验证
[root@rac1 ~]# telnet 192.168.2.102 6389
Trying 192.168.2.102...
