Adding FTP server after previous installation without ftp server

[ferit]

Dear friends,

I have a successful installation of vestacp which has been run for 2-3 months. OS is ubuntu 18.04 server without gui. Properties are dns, web, fail2ban, iptables.

Now, I need adding ftp server property to vestacp.

How can I add ftp server property to existing installations?

Is my installation corrupted if I install only the ftp server using the .sh script of vestacp?

Regards...
