3.验证

[root@tike ~]# redis-cli
127.0.0.1:6379> info replication
# Replication
role:master
connected_slaves:1
slave0:ip=172.16.18.131,port=6379,state=online,offset=70,lag=0
master_replid:bfc1c49774fe93a72eb212b49f56cc7c8ba4a410
master_replid2:0000000000000000000000000000000000000000

[root@tike ~]# redis-cli

repl_backlog_active:1
repl_backlog_size:1048576
repl_backlog_first_byte_offset:1
repl_backlog_histlen:168

4.配置密码认证

进入配置文件vi redis.conf：

/slaveof 回车搜索slaveof

在他下一行写上slaveof ip 端口号6379 如：slaveof 192.168.1.224 6379

如果主机设置了密码则：查找/masterauth 回车搜索masterauth 的下一行

masterauth 主机密码如：masterauth beijing
