启动 gunicorn.service 失败：未找到单元 gunicorn.service。乌本托 18.04

我正在关注如何在 Ubuntu 18.04 指南上使用 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

我创建了以下文件 .service

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

指南中的原始 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

我如何格式化我自己的版本我在服务器上的项目文件夹之外拥有我的虚拟环境

[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

我也尝试过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，我尝试过
