[Linux-cluster] apache resource problem in RHCS 5.1

[Ron Cronenwett]

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.

Ron C.
