在上述参考文章中，对与主从同步部署过程做了详细的操作解释，但对于三台服务器如何互相同步（即三个都是master），本文针对三台master相互同步进行配置。
1. 实现思想
三台服务器均为master，手写设定master1可以同步到master2和master3，然后设定master2和master3分别往master1同步，以此成功实现三台服务器同步机制。
2. 配置步骤
直接参考2.3.3 master上配置rsync客户端部分，分别为三台服务器配置，配置文件参考2.3.1.2 部署rsync服务 (Slave服务器上相关操作)。
注意，参考文章中的slave和master节点密码文件不一致，master是rsync.password，slave是 rsyncd.password，最好统一使用rsync.password。
2.1 三个master的rsyncd.conf文件
-
三个master节点ip
- master1 ： 192.168.0.196
- master2 ： 192.168.0.143
- master3 ： 192.168.0.150

以下是我的Master1配置文件
