Hi all,
I am trying to come up with a vanilla systemd unit file so that our RPM
packaging contains a sensible startup on systemd environments, but I’m
struggling.
With the unit file below the “systemctl restart httpd” command hangs. Usually
the server starts fine, but then the server is stopped by something a short
while afterwards for no clear reason. According to google the hang in systemctl
happens for many people, systemctl is waiting for a message that never comes,
but the causes are widely varied and I am struggling to figure out exactly what
is wrong.
What I am trying to achieve is a simple daemon start, with no mod_systemd
(which isn’t part of core httpd).
Can anyone point out any obvious errors in the following?
[Unit]
Description=The Apache HTTP Server
After=network.target remote-fs.target nss-lookup.target
Documentation=man:httpd(8)
Documentation=man:apachectl(8)
[Service]
Type=forking
PIDFile=/var/run/httpd.pid
EnvironmentFile=/etc/sysconfig/httpd
ExecStart=/usr/sbin/httpd $OPTIONS
ExecReload=/usr/sbin/httpd $OPTIONS -k graceful
ExecStop=/bin/kill -WINCH ${MAINPID}
# We want systemd to give httpd some time to finish gracefully, but still want
# it to kill httpd after TimeoutStopSec if something went wrong during the
# graceful stop. Normally, Systemd sends SIGTERM signal right after the
# ExecStop, which would kill httpd. We are sending useless SIGCONT here to give
# httpd time to finish.
KillSignal=SIGCONT
PrivateTmp=true
[Install]
WantedBy=multi-user.target
Regards,
Graham
