I'm building my own RPM for Knot 2.2.0 on Centos 7 due to the fact that the system version is still 1.x. I'm building it with systemd integration, and I've borrowed the systemd service file from the Fedora RPM. I'm having issues at startup, though. I'm wondering if it's related to the use of 'Type=notify', since knot seems to be running, but then after a delay of 30 seconds systemd decides it has failed and kills it. I'm attaching useful bits below. Any thoughts on the cause? My service file is: [Unit] Description=Knot DNS server daemon [Service] Type=notify ExecStart=/usr/sbin/knotd ExecReload=/usr/sbin/knotc reload Restart=on-abort ExecStartPre=/usr/sbin/knotc conf-check # Breaks daemon reload #CapabilityBoundingSet=cap_net_bind_service cap_setuid cap_setgid [Install] WantedBy=multi-user.target And this is what knot is reporting at startup: ● knot.service - Knot DNS Server Loaded: loaded (/etc/systemd/system/knot.service; disabled; vendor preset: disabled) Active: failed (Result: timeout) since Thu 2016-05-12 19:52:34 UTC; 3min 19s ago Process: 5875 ExecStart=/usr/sbin/knotd (code=exited, status=0/SUCCESS) May 12 19:51:04 master01.test.conundrum.com knotd[5875]: 2016-05-12T19:51:04 info: starting server May 12 19:51:04 master01.test.conundrum.com knotd[5875]: 2016-05-12T19:51:04 info: server started in the foreground, PID 5875 May 12 19:51:04 master01.test.conundrum.com knotd[5875]: 2016-05-12T19:51:04 info: control, binding to '/var/run/knot/knot.sock' May 12 19:52:34 master01.test.conundrum.com systemd[1]: knot.service start operation timed out.
