centos 搭建redis主从

centos 搭建redis主从

!!! 由于这是在虚拟机中做的测试,配置过程中可能出现错误,记得看日志

查看主从信息:  info replication

搭建主从确保,两台服务器直接可以连通, ping 连接ok, redis 互相可以登录

redis 主: 192.168.56.3      redis 从: 192.168.56.101 

我的这两台服务器redis密码都设置为123456, redis.conf 中bind 已经注释

1). 测试1:

[root@localhost vagrant]# ping 192.168.56.101
PING 192.168.56.101 (192.168.56.101) 56(84) bytes of data.

[root@localhost vagrant]# ping 192.168.56.3

测试2 , redis 互相登录:

#在192.168.56.3 上登录 192.168.56.101

[root@localhost vagrant]#  /usr/bin/redis-cli -h 192.168.56.101 -a 123456
192.168.56.101:6379> keys *



#在192.168.56.101 上登录 192.168.56.3

[root@localhost vagrant]# /usr/bin/redis-cli -h 192.168.56.3 -a 123456
192.168.56.3:6379> keys *

2).  配置主从:

在conf服务器上 redis.conf 中配置  

slaveof 192.168.56.3 6379

masterauth 123456

3). 配置完毕,测试数据:
