python - 无法启动 gunicorn.service : Unit gunicorn. 找不到服务。 Ubuntu 18.04

Question

我关注 this如何在 Ubuntu 18.04 指南中使用 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

我创建了以下文件 .service
sudo nano /etc/systemd/system/gunicorn.service
guide 中的原始 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 我在服务器上的项目文件夹之外有我的虚拟环境

[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
--bind unix:/run/gunicorn.sock \
比我尝试执行以下代码
sudo systemctl start gunicorn
错误消息 1
Failed to start gunicorn.service: Unit gunicorn.service not found.
我也试过 2
sudo systemctl start gunicorn.socket
错误消息 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，我尝试了

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

Answer 1

我花了大约三个小时...... Fxxx
不要这样做:

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

做这个:

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

和:

  sudo systemctl status gunicorn.socket

它现在工作正常 !
