Redis主从复制过程原理
1.当从库和主库建立MS关系后,会向主数据库发送SYNC命令 2.主库接收到SYNC命令后会开始在后台保存快照(RDB持久化过程),并将期间接收到的写命令缓存起来 3.当快照完成后,主Redis会将快照文件和所有缓存的写命令发送给从Redis 4.从Redis接收到后,会载入快照文件并且执行收到的缓存的命令 5.之后,主Redis每当接收到写命令时就会将命令发送从Redis，从而保证数据的一致

slave配置
#slave添加选项：
slaveof $master $port
#如果master设置密码：
masterauth $password
#slave启动非只读（默认为yes）：
slave-read-only no
#错误日志会显示I/O error trying to sync withMASTER: connection lost
>config set client-output-buffer-limit slave1024mb 256mb 0
