I’m setting up a high availability LAMP stack – so far, I have two servers with HAProxy running on both their frontends that own a floating IP. HAProxy redirects requests to backend Apache servers running on each of them (same machine, port 8000).
This all works, and I’m happy with this so far for high availability. I have yet to deal with the databases yet however.
Since I only have two servers, I don’t think I can do master-master like Galera cluster due to the requirement of quorum. So, I planned to do master-slave read only replication.
Most of the guides I see online don’t mention the MaxScale proxy that MariaDB suggests in its high availability guide (page 4 for example)
I’m just really confused overall on what to do and how to set it up?
From my perspective, I’d like to set up a MaxScale proxy on one of my servers and run MariaDB on both servers; MaxScale will handle things like redirects. How can I actually accomplish what I’m looking for?
