I created a file server with SAMBA share for a second CentOS 7 server.
As of 2.15.2018, I have phased out my CentOS7 WP server. The server was slow to backup compared to Ubuntu in VEAAM. It was more complex putting new SSL Certificates on. I created two new WP Servers in Ubuntu 16.04.5. I migrated all the web sites to them from this server.
