Apache Failed to Start in Pacemaker

In CentOS8

doing this...

pcs resource create httpd_monitor ocf:heartbeat:apache \
configfile="/etc/httpd/conf/httpd.conf" \
statusurl="http://127.0.0.1/server-status" --group apache

The file /etc/httpd/conf/httpd.conf is checked for the PidFile parameter. This is not defined, but defaults to /var/run/httpd/httpd.pid

[root@hanode1 ~]# pcs resource
  * Resource Group: apache:
    * httpd_fs  (ocf::heartbeat:Filesystem):     Started hanode1.lab.local
    * httpd_vip (ocf::heartbeat:IPaddr2):        Started hanode1.lab.local
    * apache_service    (service:httpd):         Started hanode1.lab.local
    * httpd_monitor     (ocf::heartbeat:apache):         Stopped

You get this error message

Feb 02 17:39:21 INFO: apache not running
Feb 02 17:39:21 INFO: waiting for apache /etc/httpd/conf/httpd.conf to come up

So if you define this in /etc/httpd/conf/httpd.conf

# this is the default but is required by pcs to be defined
PidFile /var/run/httpd/httpd.pid

This will run fine, as below:

[root@hanode1 ~]# pcs resource debug-start httpd_monitor
Operation start for httpd_monitor (ocf:heartbeat:apache) returned: 'ok' (0)
Feb 02 17:39:57 INFO: apache already running (pid 88022)

Then you can clean up with pcs resource cleanup httpd_monitor

# pcs resource
  * Resource Group: apache:
    * httpd_fs  (ocf::heartbeat:Filesystem):     Started hanode1.lab.local
    * httpd_vip (ocf::heartbeat:IPaddr2):        Started hanode1.lab.local
    * apache_service    (service:httpd):         Started hanode1.lab.local
    * httpd_monitor     (ocf::heartbeat:apache):         Started hanode1.lab.local
