无法启动 gunicorn.service：gunicorn.socket 的作业失败。 乌本托 18.04

Question

I am following this How To Set Up Django with Postgres, Nginx, and Gunicorn on Ubuntu 18.04 guide.

I have created the following file.socket

sudo nano /etc/systemd/system/gunicorn.socket



[Unit]
Description=gunicorn socket

[Socket]
ListenStream=/run/gunicorn.sock

[Install]
WantedBy=sockets.target

I have created the following file.service. How I have formatted my own version

sudo nano /etc/systemd/system/gunicorn.service

[Unit]
Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target

[Service]
User=guilhermenog
Group=www-data
WorkingDirectory=/home/guilhermenog/projetoagenda
ExecStart=/home/guilhermenog/projetoagenda/venv/bin/gunicorn \
       --access-logfile - \
       --workers 3 \
       --bind unix:/run/gunicorn.sock \
       agenda.wsgi:application

[Install]
WantedBy=multi-user.target

Than I have tried to execute the following code

sudo systemctl start gunicorn.socket

And i have recibed this message error

Job for gunicorn.socket failed
See "systemctl status gunicorn.socket" and "journalctl -xe" for details. 

After i tried the recommended code

● gunicorn.socket - gunicorn socket
Loaded: loaded (/etc/systemd/system/gunicorn.socket; enabled; vendor preset: enabled)
Active: inactive (dead)
Listen: /run/gunicorn.sock (Stream)

Answer 1

I had the same issue and it was also returning the same error. I managed to fix it for myself so I decided to share what I did, perhaps someone finds it useful too:

Fix: First I ran command: sudo systemctl enable gunicorn.socket (it created symlink) Then I tried running: sudo systemctl start gunicorn.socket - but it returned that the job for gunicorn socket failed, however, I ran sudo systemctl enable gunicorn.socket again and then sudo systemctl start gunicorn.socket and the issue was no more and upon checking status ( command sudo systemctl status gunicorn.socket ) it finally returned that it is active (listening).
