启动gunicorn.service失败：gunicorn.socket的任务失败。Ubuntu 18.04

Question

我正在按照这篇文章的步骤：在Ubuntu 18.04上使用Postgres、Nginx和Gunicorn设置Django。

我创建了以下文件 .socket

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



[Unit]
Description=gunicorn socket

[Socket]
ListenStream=/run/gunicorn.sock

[Install]
WantedBy=sockets.target

我已经创建了以下文件.service。以下是我自己版本的格式。

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

我尝试执行以下代码：

sudo systemctl start gunicorn.socket

我收到了这条错误信息

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

尝试了推荐的代码后

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

我按照这些建议操作了，但仍然没有任何反应。 无法启动gunicorn.service: Unit gunicorn.service未找到。Ubunto 18.04

对不起，这个问题是我第一次用英语寻求帮助。

我曾经遇到过同样的问题，也返回了相同的错误。我设法为自己解决了这个问题，所以我决定分享一下我做的事情，也许对某些人有用：

解决方法：首先我运行了命令：sudo systemctl enable gunicorn.socket（它创建了符号链接）然后我尝试运行：sudo systemctl start gunicorn.socket - 但它返回了gunicorn套接字作业失败的消息，然而，我再次运行sudo systemctl enable gunicorn.socket，然后sudo systemctl start gunicorn.socket，问题就不再存在了，并且在检查状态（命令sudo systemctl status gunicorn.socket）时，它最终返回它是活动的（正在监听）。
