CentOS: 7.1.1503

I have a problem with systemd which somehow manages to fill /tmp up with a lot of files. These files obviously are from the Apache server and don’t pose a problem per se. The problem is that these files don’t get removed daily:

du -hs systemd-private-*
7,7G systemd-private-mpg7rm
0 systemd-private-olXnby
0 systemd-private-qvJJ5o
0 systemd-private-Rs2nBv

It was my understanding that these temp-files should have been removed daily as it is stated here:

$: grep -v ‘^#’ /usr/lib/systemd/system/systemd-tmpfiles-clean.timer

  • Have you checked which process creates the files and doesn’t apparently clean them up properly by checking the contents for example?

    Yes. Those files obviously are created by web applications (PHP) and are zip files. These web application are not under my control. At the moment I am not quite sure why they are generated. They should, however, be removed daily. I’d like to solve this with systemd’s own tools instead of searching for some ‘tmp-reaper’.

  • At the risk of repeating myself, “systemd’s own tools” ARE a “tmp-reaper.”

    From “man systemd-tmpfiles-clean.timer”:
    systemd-tmpfiles creates, deletes, and cleans up volatile and temporary files and directories, based on the configuration file format and location specified in tmpfiles.d(5).
