【问题描述】：

我正在关注this 如何在 Ubuntu 18.04 上使用 Postgres、Nginx 和 Gunicorn 设置 Django 指南。

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

我创建了以下文件 .service

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

guide中的原RECOMENDED_FORMATTING-s

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


[Service]
User=sammyRECOMENDED_FORMATTING
Group=www-data
WorkingDirectory=/home/sammyRECOMENDED_FORMATTING/myprojectdirRECOMENDED_FORMATTING
ExecStart=/home/sammyRECOMENDED_FORMATTING/myprojectdirRECOMENDED_FORMATTING/myprojectenvRECOMENDED_FORMATTING/bin/gunicorn \
          --access-logfile - \
          --workers 3 \
          --bind unix:/run/gunicorn.sock \
          myprojectRECOMENDED_FORMATTING.wsgi:application

[Install]
WantedBy=multi-user.target

我如何格式化自己的版本我的虚拟环境位于服务器上的项目文件夹之外

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

[Service]
User=SERVER_USER
Group=www-data
WorkingDirectory=/home/SERVER_USER/MAIN_PROJECT_FOLDER
ExecStart=/home/SERVER_USER/ven/bin/gunicorn \
          --access-logfile - \
          --workers 3 \
          --bind unix:/home/SERVER_USER/MAIN_PROJECT_FOLDER/MAINAPPLICATION_FOLDER.sock \
          MAINAPPLICATION_FOLDER.wsgi:application

[Install]
WantedBy=multi-user.target

我也尝试按照最初的建议保留这些内容

--bind unix:/run/gunicorn.sock \

比我尝试执行以下代码

sudo systemctl start gunicorn

错误信息 1

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

我也试过 2

sudo systemctl start gunicorn.socket

错误信息 2

Failed to start gunicorn.socket: Unit gunicorn.socket is not loaded properly: Invalid argument.
See system logs and 'systemctl status gunicorn.socket' for details.

为了解决这个问题，我已经尝试过

Failed to start gunicorn.service: Unit gunicorn.service not found 这指向了我正在做的完全相同的指南，除了旧版本的 linux。
这不是同一个代码，没有回答https://askubuntu.com/questions/748836/unit-gunicorn-service-failed-to-load-no-such-file-or-directory
运行：systemctl status gunicorn.socket 结果：Warning: The unit file, source configuration file or drop-ins of gunicorn.socket changed on disk ● gunicorn.socket - gunicorn daemon Loaded: error (Reason: Invalid argument) Active: inactive (dead)
运行：systemctl is-enabled gunicorn.socket 结果：enabled
运行：systemctl is-enabled gunicorn.service 结果：Failed to get unit file state for gunicorn.service: No such file or directory

【问题讨论】：

标签： python django ubuntu gunicorn ubuntu-18.04

【解决方案1】：

花了我大约三个小时...... Fxxx

不要这样做：

  sudo systemctl start gunicorn.socket
  sudo systemctl enable gunicorn.socket

这样做：

  sudo systemctl enable gunicorn.socket
  sudo systemctl start gunicorn.socket

和：

  sudo systemctl status gunicorn.socket

现在可以正常使用了！

【讨论】：

谢谢。这是有道理的。

【解决方案2】：

这解决了它：

sudo systemctl enable gunicorn.service
