Description
Hi,
while checking fresh installed nginx service file on a new CentOS 8 server I've got this error:
systemd[1]: nginx.service: Failed to parse PID from file /run/nginx.pid: Invalid argument
so I've checked the run folder and as this looked OK for me I've checked the provided service file too:
cat /usr/lib/systemd/system/nginx.service
[Unit]
Description=The nginx HTTP and reverse proxy server
After=network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
PIDFile=/run/nginx.pid
# Nginx will fail to start if /run/nginx.pid already exists but has the wrong
# SELinux context. This might happen when running nginx -t from the cmdline.
# https://bugzilla.redhat.com/show_bug.cgi?id=1268621
ExecStartPre=/usr/bin/rm -f /run/nginx.pid
ExecStartPre=/usr/sbin/nginx -t
ExecStart=/usr/sbin/nginx
#ExecReload=/bin/kill -s HUP $MAINPID
KillSignal=SIGQUIT
TimeoutStopSec=5
KillMode=mixed
PrivateTmp=true
[Install]
WantedBy=multi-user.target
-- the defined variable for the PID is called PIDFile but "ExecReload" points to $MAINPID which isn't defined.
Solution:
changing
ExecReload=/bin/kill -s HUP $MAINPID
to
ExecReload=/bin/kill -s HUP $PIDFile
resolves the error
kind regards
Georg
Hi George,
Thank you for your report!
$PIDFile will hold the file name that has the PID, so sending a signal via ExecReload to that file wouldnt make any sense.
Additionally, that is the package provided by Red Hat, not us, so we cant really fix anything about it, too.
