Instalaltion of Seafile on CentOS7 with Directadmin

I want to install Seafile on CentOS7 with Directadmin, but I am worry to damage services which already are running on server.

In many different article mentioned: “run on a fresh installation only and should never be run on a production server, otherwise, you could lose valuable data”.

This is why I am worry. But theoretically if everything installed correctly should be no interference.

I will greatly appreciate if somebody can share with own experience by installing Seafile.
