配置环境：
Master服务器 : 192.168.189.129:44444
Slave服务器 : 192.168.189.131:44444
一：下载安装redis软件包，并解压

# cd /usr/local/src
# wget http://redis.googlecode.com/files/redis-2.6.4.tar.gz
# tar -zxvf redis-2.6.4.tar.gz
# cd redis-2.6.4
|
二：安装
redis软件不依赖其他的库，也不需要额外的编译参数，可直接make install进行安装
|
1
|
# make install
|
三：创建所需目录与文件，便于管理

# mkdir -p /usr/local/redis/bin
# mkdir -p /usr/local/redis/etc
# mkdir -p /usr/local/redis/var
# mkdir -p /usr/local/redis/data
# cp redis.conf /usr/local/redis/etc/
# cp /usr/local/bin/redis-* /usr/local/redis/bin
|
四：配置redis.conf文件如下

五：依次开启主从redis，并测试

|
Master:
# /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf
Slave:
# /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf
|
使用客户端连接主redis，并进行一些简单操作
# /usr/local/redis/bin/redis-cli -h 192.168.189.129 -p 44444
连接从redis，查看数据是否同步
# /usr/local/redis/bin/redis-cli -h 192.168.189.131 -p 44444
从上可看到数据已同步，证明redis主从配置生效
注：由于在配置文件中配置了slave-read-only yes,因此从节点处于只读状态，无法对数据库进行操作和更改。
