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  
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。

启动slave节点

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
