使用Django应用运行gunicorn的各种问题

标签: python django nginx gunicorn

我是Django的新手。试图让我的应用程序在Nginx + gunicorn下运行,但遇到了一些问题。如果有人有见识,我将不胜感激。我已经找到了一些可以在Google上尝试的方法,但gunicorn仍然显得很虚弱。

1)我已经将Django项目从我的开发箱同步到Nginx主机。如果我尝试使用开发服务器启动,则除非使用Python 3,否则它将无法正常工作。

我在下面搜索了...from exec错误,发现如果以python3为前缀,我可以使它工作。似乎是针对较大问题的解决方法,但是由于我一直关注的所有教程都未提及这种启动方式。

炸弹:

(venv) $ python manage.py runserver 127.0.0.1:8777
  File "manage.py", line 16
    ) from exc
         ^
SyntaxError: invalid syntax

这有效:

(venv) $ python3 manage.py runserver 127.0.0.1:8777
Watching for file changes with StatReloader
Performing system checks...

Quit the server with CONTROL-C.

^C(venv) $ 

2)上面,如果使用开发服务器,我可以在Nginx上很好地运行应用程序。但是,如果通过gunicorn执行,事情就会崩溃。怎么来的? Python说了cannot import name path,但它似乎可以在开发服务器上正常运行(登录页面也可以正确显示在浏览器中),所以我对问题的所在有些困惑。

您需要确保用于启动 gunicorn 的virtualenv与您在本地创建的环境匹配。

如错误跟踪所示,您的venv是使用python 2.7创建的(而您的pip freeze显示了它是安装了Django 1.11的)。

但是您的项目似乎要在Django 3.x中使用Django 2.2进行设置(它使用path)。当您执行runserver时,这也在运行。

因此,您应该使用python3创建一个新的virtualenv并重新安装所有依赖项,包括Django 2.2和gunicorn。
