Subject: Re: Run Control for Apache in Fedora 25
Thank you Mickey.
That is exactly what the problem is; all /var/run subdirectories get
deleted on reboot.
I tried to move the pid file to another location, for a start its default
location under the apache install directory, but even directly on
/var/run/, with the result that systemctl could not find it. The pid file
was written correctly, under the correct name, and was readable by root,
but was reported as missing by systemctl and as a result the "systemctl
stop httpd" command didn't work. It just issued an error message and httpd
kept right on running.
One trhing that I have been careful to do is keep the start up script at
init.d/httpd pointed at the same location as httpd.conf.
I'm not sure why but systemctl seems to insist that that the httpd pid file
be exactly /var/run/httpd/httpd.pid .
I think there must be a configuration parameter somewhere for systemctl but
I have not been able to find it; can't believe it would be hard coded in the
programme!
That said, thank you for the reply. It does give me the idea that I am on
the right track.
