Hi all,
I'm walking through the pcs cluster from scratch on RHEL 7 beta. I've
run into a couple issues and I can't tell if they're issues or just
oversites on my part.
1. If httpd is running, pacemaker thinks it is not and can not start it.
It shows:
====
Dec 27 01:11:38 an-c03n02 apache(Website)[11412]: INFO: apache not running
Dec 27 01:11:38 an-c03n02 apache(Website)[11412]: INFO: waiting for
apache /etc/httpd/conf/httpd.conf to come up
====
Until it fails over to the other node, which then shows the same thing
until it fails back. If I systemctl stop httpd.service and then let
pacemaker start it, it works mostly.
2. If pacemaker starts httpd, it prints errors in syslog:
====
Dec 27 01:26:08 an-c03n01 systemd: pacemaker.service: Got notification
message from PID 13193, but reception only permitted for PID 1965
Dec 27 01:26:18 an-c03n01 systemd: pacemaker.service: Got notification
message from PID 13193, but reception only permitted for PID 1965
====
[root@an-c03n01 ~]# cat /proc/13193/status |grep Name
Name: httpd
[root@an-c03n01 ~]# cat /proc/1965/status |grep Name
Name: pacemakerd
====
Apache does start though:
====
lynx http://127.0.0.1/server-status
====

an-c03n01.alteeve.ca:80 GET /server-status
====
3. I know I mentioned this on IRC before, but I thought I should mention
it here again. In the pcs CfS, it shows to set:
====
<Location /server-status>
SetHandler server-status
Order deny,allow
Deny from all
Allow from 127.0.0.1
</Location>
====
But then in the resource setup, it says:
====
pcs resource create WebSite ocf:heartbeat:apache \
configfile=/etc/httpd/conf/httpd.conf \
statusurl="http://localhost/server-status"; op monitor interval=1min
====
This fails because apache will not respond to 'localhost', so you need
to set 'statusurl="http://127.0.0.1/server-status"; (or change the apache
directive to 'Allow from localhost').
So did I screw something up (specially re: #2), or is this a genuine issue?
Thanks!
