CentOS7配置redis主从复制

规划

ip              port        role        
192.168.1.31    6379        master
192.168.1.32    6379        slave
192.168.1.33    6379        slave

0.关闭防火墙

systemctl stop firewald.service 
systemctl disable firewald.service

1.安装启动redis

yum install epel-release -y 
yum install redis -y 
systemctl start redis 
systemctl enable redis 

2.master配置

#vim /etc/my.cnf 
bind 0.0.0.0                //修改监听ip
port 6379                   //监听端口
daemonize yes               //后台运行      
requirepass redhat          //配置登录密码

3.slave配置

vim /etc/my.cnf 
bind 0.0.0.0 
port 6379
daemonize yes 
masterauth redhat               //如果master配置了requiress登录密码，需要配置masterauth认证
slaveof 192.168.1.31 6379       //指定master节点的ip和端口  
slave-read-only yes             //从节点只读

4.master 和slave端 验证

redis-cli -h 192.168.1.31 -a redhat info replication
redis-cli -h 192.168.1.31 -a redhat set ip 1.1.1.1 
redis-cli -h 192.168.1.31 -a redhat set port 8080 

slave验证

redis-cli -h 192.168.1.33 -a redhat 
> keys * 
redis-cli -h 192.168.1.32 -a redhat
> keys *
