Requires three pure virtual machines,server3 as

server1:172.25.45.1

server2:172.25.45.2

server3:172.25.45.3

"server1,server2"

1. reconfigure the yum source

2. configuring the /etc/hosts file

If repeated creation in the process will cause an error

Workaround:

Rm-rf/etc/cluster/cluster.conf

Restart Service (??? Pending verification)
