I have a basic django rest application in my digital ocean server (Ubuntu 16.04) with a local virtual environment. The basic wsgi.py is:
import os os.environ.setdefault("DJANGO_SETTINGS_MODULE", "workout_rest.settings") # This application object is used by any WSGI server configured to use this # file. This includes Django's development server, if the WSGI_APPLICATION # setting points here. from django.core.wsgi import get_wsgi_application application = get_wsgi_application() # Apply WSGI middleware here. # from helloworld.wsgi import HelloWorldApplication # application = HelloWorldApplication(application) I have followed step by step this tutorial: https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04
When I test Gunicorn's ability to serve the project with this command: gunicorn --bind 0.0.0.0:8000 myproject.wsgi:application All works well.
So I've tried to setup Gunicorn to use systemd service file. My /etc/systemd/system/gunicorn.service file is:
[Unit] Description=gunicorn daemon After=network.target [Service] User=ben Group=www-data WorkingDirectory=/home/ben/myproject ExecStart=/home/ben/myproject/myprojectenv/bin/gunicorn --workers 3 --bind unix:/home/ben/myproject/myproject.sock myproject.wsgi:application [Install] WantedBy=multi-user.target My Nginx configuration is:
server { listen 8000; server_name server_domain_or_IP; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/ben/myproject; } location / { include proxy_params; proxy_pass http://unix:/home/ben/myproject/myproject.sock; } } I've changed listen port from 80 to 8000 because 80 give me a err_connection_refused error. After starting the server with this command:
sudo systemctl restart nginx When I try to run my website, I get an 502 Bad Gateway error. I've tried these commands (found on the tutorial comments):
sudo systemctl daemon-reload sudo systemctl start gunicorn sudo systemctl enable gunicorn sudo systemctl restart nginx but nothing changes. When I take a look at the Nginix logs with this command:
sudo tail -f /var/log/nginx/error.log I can read that sock file doesn't exists:
2016/10/07 09:00:18 [crit] 24974#24974: *1 connect() to unix:/home/ben/myproject/myproject.sock failed (2: No such file or directory) while connecting to upstream, client: 86.197.20.27, server: 139.59.150.116, request: "GET / HTTP/1.1", upstream: "http://unix:/home/ben/myproject/myproject.sock:/", host: "server_ip_adress:8000" Why this sock file isn't created? How can I configure django/gunicorn to create this file? I have added gunicorn in my INSTALLED_APP in my Django project but it doesn't change anything.
EDIT:
When I test the nginx config file with nginx -t I get an error: open() "/run/nginx.pid" failed (13: Permission denied). But if I run the command with sudo: sudo nginx -t, the test is successful. Does that mean that I have to allow 'ben' user to run Ngnix?
About gunicorn logfile, I cannot find a way to read them. Where are they stored?
When I check whether gunicorn is running by using ps aux | grep gunicorn:
ben 26543 0.0 0.2 14512 1016 pts/0 S+ 14:52 0:00 grep --color=auto gunicorn Here is hat happens when you run the systemctl enable and start commands for gunicorn:
sudo systemctl enable gunicorn Synchronizing state of gunicorn.service with SysV init with /lib/systemd/systemd-sysv-install... Executing /lib/systemd/systemd-sysv-install enable gunicorn sudo systemctl start gunicorn I get no output with this command sudo systemctl is-active gunicorn active sudo systemctl status gunicorn ● gunicorn.service - gunicorn daemon Loaded: loaded (/etc/systemd/system/gunicorn.service; enabled; vendor preset: enabled) Active: active (exited) since Thu 2016-10-06 15:40:29 UTC; 23h ago Oct 06 15:40:29 DevUsine systemd[1]: Started gunicorn.service.
