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 *
