nohup /usr/bin/davmail /etc/conf.d/davmail.properties
as per the DavMail instructions (where
/usr/bin/davmail is a symlink to
/usr/share/java/davmail/davmail.sh). Now that I've made the computer into a headless server, I'd like the auto-launcher to be independent of an X session.
All the guides I've seen online for a DavMail initscript assume that the distro is using sysvinit, not systemd. My attempt at a custom systemd service file is
[Unit] Description=DavMail Exchange Gateway Requires=network.target After=network.target [Service] Type=forking RemainAfterExit=yes ExecStart=/usr/bin/davmail /etc/conf.d/davmail.properties ExecStop=killall davmail [Install] WantedBy=multi-user.target
which fails to fork properly. Prepending the
ExecStart command with
/usr/bin/nohup is no help, because systemd complains about an invalid argument (preferring to take control of the daemonization itself, if I'm correctly understanding previous forum answers). Changing the Service Type to
simple also fails.
I think an issue here is that DavMail requires a Java interpreter to run, and systemd service files aren't as flexible as shell scripts in handing off the job to a Java interpreter. But maybe there's a much simpler explanation. Has anyone successfully written a systemd service file for DavMail that they'd be willing to share?
