Hi all, Just curious what the communities' solutions were for high availability with their packetfence setups. We've recently purchased some hardware load balancers, which gives us more options for load balancing than we had previously, so I was considering the following setup?
1 x database server (running on VMWare with replication of the server also in place for HA) 2 x app servers (running all the PF services apart from the DB) The load balancers sending all traffic to the first server to avoid deadlocks with the database, but with a health check to switch services over to the second app server. If was to do this, what services would I need to load balance between the two app servers? Apache and radius are the obvious ones, but do I need to consider DHCP, DNS, etc for the portals? Are there any other extras that might be running under the hood that I might miss? Are violations stored in the database? It's no big deal if these wouldn't get transferred, but it would be nice if possible. Another option, in the interim, will be to have the same server setup, but the switches setup with two radius servers, so that radius requests bounce to the second server should the first not be available for whatever reason. Our main concern is for the already setup and registered users to retain their connection to the network, I'm less worried about people being able to access the registration portal. Does anyone else have any ideas or suggestions for a highly available setup? I did run the heartbeat and DRDB cluster scenario before, but I found that this caused more problems than it resolved to be honest.
