Hi,
how can I prevent files/directories like /var/run/mariadb from
being deleted on reboot? Lighttpd has the same problem.
This breaks services and makes servers non-restartable by anyone
else but the administrator who needs to re-create the needed files
and directories every time and has to figure out what selinux
labels they need. This causes unnecessary downtimes.
This is entirely inacceptable. This totally sucks.
On CentOS 7 machines, the /run mountpoint (available via symlink as
/var/run) is a temporary filesystem. Try "df -h /run" to see for
yourself. That whole directory lives in memory.
Using systemd-tmpfiles is the most reliable method for ensuring your
/run directories are created and given correct perms at boot. The
syntax for /etc/tmpfiles.d/*.conf isn't terribly difficult, and the
files there are easy to manage. See the tmpfiles.d(5) man page for
details and examples.
Once your file is in place, you can activate it without messing with
other temp files:
systemd-tmpfiles --create /etc/tmpfiles.d/your.conf
