【主從同步實(shí)戰(zhàn)】（主跟從可以在相同服務(wù)器，同服務(wù)器的時(shí)候必須至少要有兩個(gè)實(shí)例）

主：6379  從：6380   -》同一臺(tái)服務(wù)器，不同實(shí)例

1）從修改配置文件

sed -i "210a slaveof 192.168.1.103 6379" /usr/local/redis/6380/conf/redis.conf  #此處不寫主的IP寫主的域名也可以
sed -i "217a masterauth wsyht" /usr/local/redis/6380/conf/redis.conf #master沒密碼可以不做這一步
redis-cli -p 6380 shutdown
redis-server /usr/local/redis/6380/conf/redis.conf &

2）建庫驗(yàn)證查看，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）從查看庫和狀態(tài)信息，monitor監(jiān)控每十秒拼一次

[root@localhost ~]# redis-cli -p 6380 
127.0.0.1:6380> monitor
OK
