In the above reference article, a detailed operation explanation is given for the synchronization deployment process with the master-slave, but for how the three servers synchronize with each other (that is, all three are masters), this article configures the three masters for mutual synchronization.
1. Realize ideas
The three servers are all masters, and the handwritten setting master1 can be synchronized to master2 and master3, and then set master2 and master3 to synchronize to master1 respectively, so as to successfully realize the synchronization mechanism of the three servers.
2. Configuration steps
Directly refer to the section of 2.3.3 Configuring the rsync client on the master , which is configured for the three servers respectively. For the configuration file, refer to 2.3.1.2 Deploying the rsync service (related operations on the slave server) .
Note that the slave and master node password files in the reference article are inconsistent. The master is rsync.password, and the slave is rsyncd.password. It is best to use rsync.password uniformly.
2.1 The rsyncd.conf files of the three masters
-
Three master node ip
- master1 ： 192.168.0.196
- master2 ： 192.168.0.143
- master3 ： 192.168.0.150
