Install three network cards on the main server

192.168.136.229

192.168.136.232

192.168.136.231

Install three network cards from the server

192.168.136.185

192.168.136.233

192.168.136.234

Both servers restart network services

[root@localhost opt] # systemctl restart network

Two servers turn off firewalls and enhancements

[root@localhost opt] # systemctl stop firewalld.service

[root@localhost opt] # setenforce 0
