Hi I probably just didn't explain myself too well yesterday - not enough coffee yet. Maybe if I explain what I'm trying to do, then you can give an opinion on the best way to go. I have two physical machines, now with two virtual nodes (Xen) on both. All the nodes are using Ubuntu server 8.04 as an OS. One (LB1 and LB2), has HAProxy and Heartbeat. The other (WEB1 and WEB2) has a LAMP setup along with ISPConfig to aid in setting up web sites. I also have Gb NIC's in both with a crossover cable, just for rsync, and DB replication. We will be hosting several web sites, most which are very basic, but a couple will be Drupal CMS sites, with moderate traffic. The CMS sites will be the ones that will also need SSL. I want auto failover, but I've never made up my mind on if we really need load balancing. If I get rid of the load balancer, I can remove the LB nodes, and just use Heartbeat with the web server. I know that sounds like the simplest way to go, but am I shooting myself in the foot by removing the possible load balancer need in the future. If I keep it as it is, then I need to get SSL working through HAProxy, which is looking a bit complicated. So that's the saga so far. I just need to decide which way will be the best, but I'm running out of time because I need to get this operational. Thanks for the help.

Why would you run heartbeat in one VM and web server in another? Basically, you have two options: run cluster within the VMs, it would then manage web server and such, or manage whole VMs on the hosts using the Xen RA (or vmware). > I > will also need SSL capabilities too. SSL where? For the web server? Just make sure that it doesn't ask for the passphrase for the certificate. > As long as I don't need load balancer, I'm already replicating the > Mysql DB, and rsync is doing the files, is that all I need to do auto failover? Probably, but test it thoroughly. Just make sure that your files are consistent with the database, if that's possible. Thanks, Dejan > I hope > I'm not sounding too slow here.
