redis的主从配置方法详解

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。

				?

									root  32507 29770 0 17:51 pts/1 00:00:00 redis-server /etc/redis_slave.conf

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

									:1

									rpush data 1

									:2

									lrange data 0 -1

									*2

									$1

									1

									$1

									1

slave节点验证

				?

									[root@rac1 ~]# telnet 192.168.2.102 6389

									Trying 192.168.2.102...

									Connected to rac2.localdomain (192.168.2.102).

									Escape character is '^]'.

									lrange data 0 -1

									*2

									$1

									1

									$1

									1

									quit

									+OK

									Connection closed by foreign host.

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
