I build up a Web, Email And MySQL Database Cluster (Mirror) On Debian 6 according to the tutorial from Falko, I have 2 load balancers and 2 nodes, I'm balancing http and smtp with HAproxy, everything seems to be ok just some little things dont work as I expect... I have no previous experience with clusters so I'm not shure if the issues are normal or not, so please could somebody help me understand this.
1. when I try to access ispconfig3 over the virtual IP it fails but when I use one of the nodes IP's it will work.
2. when I try to access webmail (squirrelmail) over the virtual IP it works fine but when I try it like this: http://www.somedomain.tld/squirrelmail
points to the virtual IP)
I will get the login screen but my username & password will not be accepted, this issue is a little bit anoying.
3. when I try to receive & send mail over the virtual IP it fails but when I use one of the nodes IP's it works fine, transports to the virtual IP work also well.
thanks in advance!
