I'm trying to create a systemd service that executes a custom script I wrote. It is just a backup script that I am using with a systemd timer. When I try to execute something simple in the systemd file like "/usr/bin/free" or something like that, it works perfectly. However when I try to execute my script "/root/scripts/mybackupscript.sh", it fails with:
Main process exited, code=exited, status=203/EXEC
If I set selinux to permissive, it will start my script with no problem.
So I know that selinux is restricting systemd from executing my script. But I don't know how to use selinux. How do I create an selinux context to allow systemd to execute my script?
Example: This systemd file runs no problem:
[Unit] Description=Logs system statistics to the systemd journal Wants=myMonitor.timer [Service] Type=oneshot ExecStart=/usr/bin/free [Install] WantedBy=multi-user.target But this script fails (unless if I set selinux to permissive, in which case it executes fine):
[Unit] Description=Logs system statistics to the systemd journal Wants=myMonitor.timer [Service] Type=oneshot ExecStart=/root/scripts/mybackupscript.sh [Install] WantedBy=multi-user.target Any ideas would be appreciated. Thanks!
