liunx简单部署redis主从配置

首先准备三台以安好的redis，选择一台做主俩台做从服务器
redis-master----192.168.246.202
redis-slave-1-----192.168.246.203
redis-slave-2-----192.168.246.204
编辑master的redis配置文件
[root@redis-master redis]# vim redis.conf

修改slave1的配置文件
[root@redis-slave-1 redis]# vim redis.conf

修改slave2的配置文件
[root@redis-slave-2 redis]# vim redis.conf #和slave1一样
4.重启三台redis
systemctl restart redis
5.测试主从
1.在master上面执行
[root@redis-master redis]# cd src/
[root@redis-master src]# ./redis-cli
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> set name xuan
OK
127.0.0.1:6379> get name
“xuan”
127.0.0.1:6379>
2.分别在slave-1和slave-2上面执行:
[root@redis-slave-1 redis]# cd src/
[root@redis-slave-1 src]# ./redis-cli
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> get name
“xuan”
127.0.0.1:6379>
[root@redis-slave-2 src]# ./redis-cli
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> get name
“xuan”
127.0.0.1:6379>
查看复制状态
master执行：
127.0.0.1:6379> info replication
#Replication
role:master
connected_slaves:2
slave0:ip=192.168.246.203,port=6379,state=online,offset=490,lag=0
slave1:ip=192.168.246.204,port=6379,state=online,offset=490,lag=1

slave上面执行：
127.0.0.1:6379> info replication
#Replication
role:slave
master_host:192.168.246.202
master_port:6379
master_link_status:up
