Redis Master-Slave 读写分离测试

1 master/slave server 启动

利用默认redis.conf配置文件启动master server,端口6379 。

[7304] 29 Aug 09:57:26 - 0 clients connected (0 slaves), 673996 bytes in use

[7304] 29 Aug 09:57:31 - DB 0: 15 keys (0 volatile) in 16 slots HT.

[7304] 29 Aug 09:57:31 - 0 clients connected (0 slaves), 673996 bytes in use

[7304] 29 Aug 09:57:36 - DB 0: 15 keys (0 volatile) in 16 slots HT.

[7304] 29 Aug 09:57:36 - 0 clients connected (0 slaves), 673996 bytes in use

[7304] 29 Aug 09:57:41 - DB 0: 15 keys (0 volatile) in 16 slots HT.

修改redis配置文件， 主要修改端口为6380，不是默认的6379， 然后修改slaveof字段，设置主master为127.0.0.7 6379

启动后如下

主master已经检测到有一个slave连接

[7304] 29 Aug 09:59:06 - 0 clients connected (1 slaves), 681960 bytes in use

客户端如果连接到slave，则slave如下显示：

[1704] 29 Aug 10:05:52 - 2 clients connected (0 slaves), 689700 bytes in use

[1704] 29 Aug 10:05:57 - DB 0: 15 keys (0 volatile) in 16 slots HT.

[1704] 29 Aug 10:05:57 - 2 clients connected (0 slaves), 689700 bytes in use

[1704] 29 Aug 10:06:02 - DB 0: 15 keys (0 volatile) in 16 slots HT.

[1704] 29 Aug 10:06:02 - 2 clients connected (0 slaves), 689700 bytes in use

如果连接到master，则结果如下

[7304] 29 Aug 10:06:53 - Accepted 127.0.0.1:65311

[7304] 29 Aug 10:06:57 - DB 0: 15 keys (0 volatile) in 16 slots HT.

[7304] 29 Aug 10:06:57 - 1 clients connected (1 slaves), 689788 bytes in use

[7304] 29 Aug 10:07:02 - DB 0: 15 keys (0 volatile) in 16 slots HT.

[7304] 29 Aug 10:07:02 - 1 clients connected (1 slaves), 689788 bytes in use

2 Replication测试

在master存贮一个值，如下

?
连接到slave查询，已经自动复制。如下

?
slave我这里默认是读写都可以的，一般应该默认是只读的，这个可以再配置文件修改！

读写分离，类似于mysql cluster提供的读写分离，机制是一样的。
