I noticed your post about wanting to remove OpenVPN from your CentOS 7 server. It can be frustrating when you can't find the answers you need online. Have you considered looking into extended support for
CentOS 7 EOL? It might be a good idea to explore this option since you're running an older version of CentOS that is no longer supported by the community. As for removing OpenVPN, have you tried using the package manager to uninstall it? You can try running the following command in the terminal: "sudo yum remove openvpn". This should remove the OpenVPN package from your server.
