独角兽未开始投掷 gunicorn.service：失败，结果为"退出代码"。错误

Question

我正在尝试在Digital Ocean上部署一个简单的Django应用程序，方法是按照这个[链接][1] 我一步一步地遵循每个工作，并通过python成功运行该项目 manage.py runserver，它没有抛出任何错误，但是当我尝试用gunicorn实现它时，它抛出了以下错误

gunicorn.service：失败，结果为"退出代码"。

这是我的以下配置：

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

[Unit]
Description=gunicorn socket
[Socket]
ListenStream=/run/gunicorn.sock
[Install]
WantedBy=sockets.target

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

[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 status gunicorn.socket

当我尝试启动枪角兽时，它会抛出此错误

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 gunicorn (20.0.3( 可能会导致此问题。

尝试安装旧版本的 gunicorn：

pip install gunicorn==20.0.2

Answer 2

似乎您正在尝试用ExecStart收听unix:/run/gunicorn.sock，但是套接字处于run/gunicorn.socket。尝试更改此设置并运行systemctl daemon-reload以查看是否有所作为。
