What I wanted you to see there, is the installation process. There is a different one for SUSE (11 and 12): https://i-doit.atlassian.net/wiki/pages/viewpage.action?pageId=10223840
As you can see, SLES 11 is described in the bottom of the article but it is not supported anymore.
I remember SELinux to prevent a local connection between the webserver and the database. Perhaps you have to disable that.
