Gunicorn没有开始投掷gunicorn.service:失败的结果‘退出-代码’。错误

Question

我正在数字海洋上尝试部署一个简单的Django应用程序，我按照这个链接一步一步地执行每个工作，并通过python manage.py runserver成功地运行了该项目，在那里它没有抛出任何错误，但是当我尝试用gunicorn实现它时，它的抛出跟随错误。

gunicorn.service:失败与结果‘退出-代码’。

下面是我的以下配置：

/etc/systemd/system/gunicorn.socket纳米

[Unit]
Description=gunicorn socket

[Socket]
ListenStream=/run/gunicorn.sock

[Install]
WantedBy=sockets.target

/etc/systemd/system/gunicorn.service纳米

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

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

[Install]
WantedBy=multi-user.target

sudo systemctl gunicorn.socket gunicorn.socket

● gunicorn.socket - gunicorn socket
   Loaded: loaded (/etc/systemd/system/gunicorn.socket; enabled; vendor preset: enabled)
   Active: active (listening) since Tue 2019-11-26 07:39:39 UTC; 12min ago
   Listen: /run/gunicorn.sock (Stream)
   CGroup: /system.slice/gunicorn.socket

当我试图启动火鸟时，它会抛出这个错误

sudo systemctl status gunicorn

有人帮我解决这个问题吗? 1：https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04

Answer 1

最新版本的古尼科恩(20.0.3)可以引起这种问题。

试着安装一个较旧版本的火鸟：

pip install gunicorn==20.0.2

您似乎正在尝试在ExecStart中侦听ExecStart，但套接字位于run/gunicorn.socket。尝试更改它，然后运行systemctl daemon-reload，看看它是否会产生影响。
