I'm trying to create a runtime folder at
/run/gunicorn for some Gunicorn socket / PID files, which are for a Django application. I can get everything working if I manually create directories. However, I'm trying to make this a robust setup, and eventually use Ansible to automate everything.
I think I have 2 options, based on this question.
Option 1 - RuntimeDirectory
I think the first option is to use
RuntimeDirectory= within my systemd service file, but I can't get it to create the folder. The service files contains:
#/etc/systemd/system/gunicorn_django_test.service [Unit] Description=gunicorn_django daemon After=network.target [Service] User=gunicorn Group=www-data RuntimeDirectory=gunicorn #This line is supposed to create a directory RuntimeDirectoryMode=755 PIDFile=/run/gunicorn/django_test_pid WorkingDirectory=/vagrant/webapps/django_venv/django_test ExecStart=/vagrant/webapps/django_venv/bin/gunicorn --pid /run/gunicorn/django_test_pid --workers 3 --bind unix:/run/gunicorn/django_test_socket django_test.wsgi --error-logfile /var/log/gunicorn/django_test_error.log ExecReload=/bin/kill -s HUP $MAINPID ExecStop=/bin/kill -s TERM $MAINPID PrivateTmp=true [Install] WantedBy=multi-user.target
When I run
systemctl start gunicorn_django_test.service, the service fails to start. When I snip out the exec line, and run it manually, I get
Error: /run/gunicorn doesn't exist. Can't create pidfile. If I create the
/run/gunicorn folder manually, I can get things to work.
Option 2 - tmpfiles.d
The second option is to use
tmpfiles.d to have a folder created on boot, ready for the pid / socket files. I've tried this file:
#/etc/tmpfiles.d/gunicorn.conf d /run/gunicorn 0755 gunicorn www-data -
This creates a directory, but it is quickly deleted somehow, and by the time I start the service, the folder isn't available.
I can manually add some PreExec
mkdir commands into the service file, but I'd like to get to the bottom of why RuntimeDirectory / tmpfiles.d aren't working. Thanks.
