here is what I'm trying:
- two instances of SL7.1 with nginx as reverseproxy
- no shared filesystem
- shared resources:
- virtual IP
- running nginx service
I already tried keepalived and corosync + pacemaker.
keepalived had problems with vrrp-scripts: There was a bug that the script didnt check, if the service nginx is running. So the failover only worked when the server was shutdown.
corosync + pacemaker had the problems that I needed to configure fencing with fence-agents-vmware-soap which is not possible here (comapany policys). The reverseproxy is located in the DMZ and for communication with the VMWare-Host, the Firewall had to be changed which was no declined.
Do you have hints, howtos, etc. for doing the whole thing again?
Thanks
