Server A: Virtualmin Pro on a server with one public IP Server B: Virtualmin GPL on a server with one public IP
Server B acts as a secondary mailserver and as a DNS slave (all done within Virtualmin and this works great!)
Now I like to host my MySQL also on Server B. There is an option in Virtualmin (System Setting -> Cloudmin Services Client). Is this the way to go? Do I have other possibilities in Virtualmin to setup a secure public connection between my 2 servers?
I am concerned because the traffic is going over the intenet between 2 totally different public IPs? My websites/PHP-scripts run on serverA where the password to connect to the database resides Untill now there was no security problem because everything was on the same machine (localhost)
I am also concerned about Roundcube which uses also MySQL. I would prefer that the databases for RoundCube to stay on serverA.
Can you give me some directions on the best way to go?
Thanks in advance!
