Bebop wroteYes it is possible.
How?
Its recommended that you take care of all certificate generation and management from a separate machine. So, when you do the OpenVPN setup and install on each VPS, what you don't want to do each time, is follow the guide for generating certificates. Just setup the server.conf only on each vps.
On your home computer, or some other (non vpn) VPS, you can generate certs and distribute them to all your VPS'.
So, /etc/openvpn/some_meaningful_name/ca.crt <--- on each VPS
sir can this solution create multiple vps using one ca.crt?
we saw lot of vpn provider has multiple server with only one ca.crt on there client config.
