I am trying to understand how a vps works, I have already installed and reinstalled different operating systems many times and sometimes already with the certificate installed.
The problem is that every time I reinstall, I lose the certificate.
Is it possible to use an existing certificate after reinstallation?
My domain is: bubcasa.pt
The operating system my web server runs on is (include version): Centos 7 + vestacp
I can login to a root shell on my machine (yes or no, or I don't know): yes, but i have no knowledge.
Thanks
