*******************************************************************************
环境描述：
主redis：192.168.10.1 6379
从redis：192.168.10.2 6380
一、主从配置
1、将主从redis配置文件redis.conf中的aemonize no 改为 yesport 6379 改为 6380，添加3、启动主从服务
主redis：
[root@localhost redis-2.8.3]# src/redis-server /soft/redis-2.8.3-master/redis-2.8.3/redis.conf
从redis：
[root@localhost redis-2.8.3]# src/redis-server /soft/redis-2.8.3-slave/redis-2.8.3/redis.conf
4、测试数据同步
主redis：
[root@localhost redis-2.8.3]# src/redis-cli -p 6379
127.0.0.1:6379> set name abc
OK
127.0.0.1:6379> get name
"abc"
127.0.0.1:6379>
从redis：
[root@localhost redis-2.8.3]# src/redis-cli -p 6380
127.0.0.1:6380> get name
"abc"
127.0.0.1:6380>
5、默认是读写分离的
在从redis：
[root@localhost redis-2.8.3]# src/redis-cli -p 6380
127.0.0.1:6380> set name 123
(error) READONLY You can't write against a read only slave.
二、主从切换
1、停止主redis
[root@localhost redis-2.8.3]# src/redis-cli -n 6379 shutdown
[root@localhost redis-2.8.3]# src/redis-cli -p 6379
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected>
2、将从redis设成主redis
[root@localhost redis-2.8.3]# src/redis-cli -p 6380 slaveof NO ONE
OK
3、测试从redis是否切换从主redis
[root@localhost redis-2.8.3]# src/redis-cli -p 6380
127.0.0.1:6380> set name 123
OK
127.0.0.1:6380> get name
"123"
127.0.0.1:6380>
4、原来的主redis恢复正常了，要重新切换回去
1）将现在的主redis的数据进行保存
[root@localhost redis-2.8.3]# src/redis-cli -p 6380
127.0.0.1:6380> get name
"abc"
127.0.0.1:6380> set name 123
OK
127.0.0.1:6380> get name
"123"
127.0.0.1:6380> save
OK
127.0.0.1:6380> get name
"123"
127.0.0.1:6380>
2）将现在的主redis根目录下dump.rdb文件拷贝覆盖到原来主redis的根目录
3）启动原来的主redis
[root@localhost redis-2.8.3]# src/redis-server /soft/redis-2.8.3-master/redis-2.8.3/redis.conf
4）在现在的主redis中切换
OK
