【主从同步实战】（主跟从可以在相同服务器，同服务器的时候必须至少要有两个实例）
主：6379 从：6380 -》同一台服务器，不同实例
1）从修改配置文件
sed -i "210a slaveof 192.168.1.103 6379" /usr/local/redis/6380/conf/redis.conf #此处不写主的IP写主的域名也可以 sed -i "217a masterauth wsyht" /usr/local/redis/6380/conf/redis.conf #master没密码可以不做这一步 redis-cli -p 6380 shutdown redis-server /usr/local/redis/6380/conf/redis.conf &
2）建库验证查看，主操作
[root@localhost conf]# redis-cli -p 6379 -a wsyht 127.0.0.1:6379> set name wsyht OK 127.0.0.1:6379> get name "wsyht" 127.0.0.1:6379> select 1 OK 127.0.0.1:6379[1]> set name peter OK 127.0.0.1:6379[1]>info #查看所有信息包括同步 127.0.0.1:6380>info replication #只查看他的同步信息
3）从查看库和状态信息，monitor监控每十秒拼一次
[root@localhost ~]# redis-cli -p 6380 127.0.0.1:6380> monitor OK 1446980247.929617 [0 192.168.1.103:6379] "PING" 1446980257.981266 [0 192.168.1.103:6379] "PING" 1446980268.034426 [0 192.168.1.103:6379] "PING" 1446980273.602672 [0 192.168.1.103:6379] "SELECT" "0" 1446980273.602687 [0 192.168.1.103:6379] "set" "name" "wsyht" 1446980278.089068 [0 192.168.1.103:6379] "PING" 1446980288.140236 [0 192.168.1.103:6379] "PING" 1446980294.722701 [0 192.168.1.103:6379] "SELECT" "1" 1446980294.722721 [1 192.168.1.103:6379] "set" "name" "peter" 1446980298.190898 [1 192.168.1.103:6379] "PING" ^C [root@localhost ~]# redis-cli -p 6380 127.0.0.1:6380> get name #查看同步过来的库 "wsyht" 127.0.0.1:6380>info #查看所有信息包括同步 127.0.0.1:6380>info replication #只查看他的同步信息
