Hi Ron
Thanks for replying! Your answer gave me some tipps, but none of them worked for me. I don't have SELinux enabled or permissive, it's disabled anyway.
I couldn't make it working with the apache resource. For me it seems quite unstable and it's nowhere really mentioned in any documentation I found. So please, if any RedHat guy is reading this, can
you please improve this feature and put it into the official documentation. For example, why does the apache.sh script change the "Listen" directive? How can I execute apache.sh manually to debug the
resource?
My workaround: I altered the default httpd script and made a script resource. In that case it's working as expected. The only thing that bothers me quite a lot is the relocation time. It takes about
50 to 60 seconds to relocate 5 IPs, a GFS mount and the apache script resource! Is this a reasonable time? On older clusters I remember times around 5 to 10 seconds.
Kind regards
Lorenz

Hi Lorenz
I had a similar problem while testing with Centos 5.1 on a VMWare
workstation setup. One more difference, I have been using
system-config-cluster
to configure the cluster. Luci seemed to be giving me problems with
setting up a mount of an NFS export. But I have not retried Luci since
changing
the selinux setting I mention below.
I found if I did not configure SELinux with setenforce permissive, the
/usr/share/cluster/apache.sh script did not execute. Once that runs,
it creates
/etc/cluster/apache/apache:"name". In that subdirectory, the script
creates an httpd.conf file from /etc/httpd/httpd.conf. I also found
the new httpd.conf
had the Listen statement commented out even though I had set it to my
clustered address in /etc/httpd/httpd. I needed to manually uncomment
the
Listen statement on each node in /etc/cluster/apache/apache:"name"/httpd.conf.
Hope this helps.

Hello everybody
I have the following test setup:
- RHEL 5.1 Cluster Suite with rgmanager-2.0.31-1 and cman-2.0.73-1
- Two VMware machines on an ESX 3.5 U1, so no fence device (it's only a test)
- 4 IP resources defined
- GFS over DRBD, doesn't matter, because it doesn't even work on a local disk
Now I would like to have an "Apache Resource" which i can select in the luci interface. I assume it's using the /usr/share/cluster/apache.sh script. If I try to start it, the error message looks like
this:

I've another cluster in which I had to alter the default init.d/httpd script to be able to run multiple apache instances (not vhosts) on one server. But there I have the Apache Service configured with
a "Script Resource".
Is this supposed to work of is it a feature in development? I don't see something like "Apache Resource" in the current documentation.
Kind Regards
