Permission denied when executing script via `systemd` service on RHEL 8
Quick question that's been bugging me - I'm getting frustrated with I'm working on a project and hit a roadblock. I'm trying to run a Python script as a systemd service on RHEL 8, but I keep getting a `Permission denied` behavior when the service attempts to execute the script. Here's my setup: I've created a service file at `/etc/systemd/system/my_script.service` with the following content: ```ini [Unit] Description=My Python Script [Service] ExecStart=/usr/bin/python3 /path/to/my_script.py User=myuser Group=mygroup WorkingDirectory=/path/to Restart=always [Install] WantedBy=multi-user.target ``` I've made sure that `my_script.py` has executable permissions set: ```bash chmod +x /path/to/my_script.py ``` However, when I try to start the service using `systemctl start my_script`, I see the following behavior in the journal logs: ```bash journalctl -xe ``` This outputs: ``` May 12 10:00:00 myhostname systemd[1]: my_script.service: Failed to execute command: Permission denied May 12 10:00:00 myhostname systemd[1]: my_script.service: Main process exited, code=exited, status=203/EXEC ``` I’ve checked the ownership of the script, and it matches the `User` and `Group` specified in the service file. I’ve also verified that SELinux is in permissive mode: ```bash getenforce ``` This returns `Permissive`. I even tried running the script manually as `myuser` and it works fine. Is there something I’m missing in the service configuration or permission setup? Any help would be greatly appreciated! For context: I'm using Python on macOS. Has anyone else encountered this? I recently upgraded to Python latest. Has anyone else encountered this? This is part of a larger REST API I'm building.
