Wiring uWSGI to work with Django and nginx on Ubuntu 16.04

  • 772

I am trying to follow this tutorial to setup uWSGI with Django and nginx on Ubuntu16.04.

It all works fine up until the very last step (oh the irony...) where I try to execute this command:

sudo service uwsgi start

If fails with the following error:

Failed to start uwsgi.service: Unit uwsgi.service not found.

Others seem to get a similar error:

Failed to start uwsgi.service: Unit uwsgi.service failed to load: No such file or directory.

The issue appears to be related to the version of Ubuntu. While that tutorial is aimed at Ubuntu 14.04, it seems it will not work for newer versions because in version 15 Ubuntu switched from the upstart init daemon to the systemd init daemon.

How can I use systemd to launch uWSGI so that it works with nginx and Django?

ubuntu django nginx uwsgi wsgi

    The first modification needed is to the /etc/uwsgi/sites/firstsite.ini file. The only change needed is replacing the permissions from 664 to 666. The script would look like this:

    [uwsgi]
project = firstsite
base = /home/user

chdir = %(base)/%(project)
home = %(base)/Env/%(project)
module = %(project).wsgi:application

master = true
processes = 5

socket = %(base)/%(project)/%(project).sock
chmod-socket = 666
vacuum = true

    Secondly, as we're using systemd rather than upstart, the following file is not needed and can be removed: /etc/init/uwsgi.conf

    Third, we create the following systemd script at /etc/systemd/system/uwsgi.service:

    [Unit]
Description=uWSGI Emperor service
After=syslog.target

[Service]
ExecStart=/usr/local/bin/uwsgi --emperor /etc/uwsgi/sites
Restart=always
KillSignal=SIGQUIT
Type=notify
StandardError=syslog
NotifyAccess=all

[Install]
WantedBy=multi-user.target

    Refresh the state of the systemd init system with this new uWSGI service on board

    sudo systemctl daemon-reload

    In order to start the script you'll need to run the following:

    sudo systemctl start uwsgi

    In order to start uWSGI on reboot, you will also need:

    sudo systemctl enable uwsgi

    You can use the following to check its status:

    systemctl status uwsgi

  2. To get around that error: sudo systemctl daemon-reload for the newly created uwsgi.service file to be loaded.

    To make service start on each reboot: sudo systemctl enable uwsgi.
