[ClusterLabs] Trouble setting up selfcompiled Apache in a pacemaker cluster on Oracle Linux 6.8

[Souvignier, Daniel]

Hi List,

 

I've got trouble getting Apache to work in a Pacemaker cluster I set up
between two Oracle Linux 6.8 hosts. The cluster itself works just fine, but
Apache won't come up. Thing is here, this Apache is different from a basic
setup because it is selfcompiled and therefore living in /usr/local/apache2.
Also it is the latest version available (2.4.25), which could also be
causing problems. To be able to debug, I went into the file
/usr/lib/ocf/resources.d/heartbeat/apache and "verbosed" it by simply adding
set -x. This way, I can extract the scripts output from the logfile
/var/log/cluster/corosync.log, which I appended to this email (hopefully it
won't get filtered). 

 

The command I used to invoke the apache script mentioned above was:

pcs resource create httpd ocf:heartbeat:apache
configfile=/usr/local/apache2/conf/httpd.conf
httpd=/usr/local/apache2/bin/httpd statusurl=http://localhost/server-status
envfiles=/usr/local/apache2/bin/envvars op monitor interval=60s

 

Before you ask: the paths are correct and mod_status is also configured
correctly (works fine when starting Apache manually). I should also add that
the two nodes which form this cluster are virtual (Vmware vSphere) hosts and
living in the same network (so no firewalling between them, there is a
dedicated firewall just before the network). I assume that it has something
to do with the handling of the pid file, but I couldn't seem to fix it until
now. I pointed Apache to create the pid file in /var/run/httpd.pid, but that
didn't work either. Suggestions on how to solv this? Thanks in advance!

 

Kind regards,

Daniel Souvignier

 

P.S.: If you need the parameters I compiled Apache with, I can tell you, but
I don't think that it is relevant here.
