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

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
|
1
|
[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
|
1
2
|
# 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
|
1
|
[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。

好了，到此主从redis已经配置完成并成功运行了，Linux系统下的redis主从配置方法操作很简单只要接步骤认真配置基本都可以配置成功
