Redis-主从复制-测试主从模式下的读写操作

1、在主机6379写入数据

127.0.0.1:6379> keys *
(empty array)
127.0.0.1:6379> set uname jim
OK
127.0.0.1:6379> get uname
"jim"
127.0.0.1:6379> 

2、在从机6380上写数据报错

127.0.0.1:6380> set address usa
(error) READONLY You can't write against a read only replica.
127.0.0.1:6380> 

3、从机只能读数据，不能写数据

127.0.0.1:6380> set address usa
(error) READONLY You can't write against a read only replica.
127.0.0.1:6380> get uname
"jim"
127.0.0.1:6380>
