I would like to setup a shared hosting server, and then have that server mirrored to another server in another data center. So that when the main server fails I can switch to the second server (by changing all DNS). If I understand correctly, this would be a good way to achieve that: https://www.howtoforge.com/tutorial...abase-cluster-on-debian-8.4-with-ispconfig-3/ But... I would very much like to use Ubuntu 18.04 instead of Debian 8. The tool used in that manual does not yet seem to support Ubuntu. How hard would it be to create the mirroring without that tool?
