custom systemd httpd service fails to start on centos 7

mariogarcia · 02-09-2016, 09:39 AM

I have the following systemctl service

Code:

[Unit]
Description=The Apache HTTP Server for foobar
After=network.target remote-fs.target nss-lookup.target
Documentation=man:httpd(8)
Documentation=man:apachectl(8)

[Service]
Type=notify
EnvironmentFile=/etc/sysconfig/httpd
ExecStart=/usr/sbin/httpd -f /etc/httpd/conf.d/httpd.foobar.conf
ExecReload=/usr/sbin/httpd -f /etc/httpd/conf.d/httpd.foobar.conf -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

the service fails with a timeout:
systemctl status httpd_foobar.service
â httpd_foobar.service - The Apache HTTP Server for foobar

is it something related to selinux?

when i restart manually via the command line:
it works but not when trying via systemctl.

did you write that service file yourself?
have you looked up centos wiki, then apache wiki, then systemd documentation? (*)
if this is apache, are you sure you need httpd to start it? i have a debian server and it doesn't have httpd in $PATH.

(*) archwiki has always been very helpful with systemd

Hello
I wrote the service file based in the one that comes with the rpm. i just changed the ExecStart and Execreload..

i have set up selinux as permissive but the problem is not related to selinux..

I have read the documentation of systemd. centos and apache but I did not find any hints as to whiy systemd hangs out... that Is why I reached out to see if someone has any ideas..

thanks in advance.

undo that stuff.

try

Code:

# systemctl start apache2

instead (*).

if that works, do

Code:

# systemctl enable apache2

assuming you just want to start your apache server - you never said what you actually want.

(*) at least this is how it works on debian stable. alternatively, i think you can also use apachectl.
