NGINX，带有CGI插件的uWSGI，Python脚本-502坏网关

我想使用uWSGI和CGI插件来处理从NGINX传递到

.py

文件的所有请求

NGINX服务器配置：

location ~ \.py$ {
    include         uwsgi_params;
    uwsgi_modifier1 9;
    uwsgi_pass      unix:/var/www/html/cgi-bin/wsgi.sock;
}

uWSGI配置：

[uwsgi]
plugin-dir = /usr/lib/uwsgi/plugins
plugins = cgi
cgi = /var/www/html/cgi-bin
cgi-allowed-ext = .py
cgi-helper = .py=python
master = true
processes = 5
socket = wsgi.sock
chmod-socket = 664
vacuum = true
die-on-term = true

uWSGI启动输出：

$ sudo -u www-data uwsgi --ini uwsgi.ini 
[uWSGI] getting INI configuration from uwsgi.ini

/var/www/html/cgi-bin/

中有两个文件：

• info.py

• some.py

如果我用任何其他文件名打开URL，我会从uWSGI得到

404

错误-这很好。但是，如果我打开一个带有实际脚本名的URL，那么我会从uWSGI获得

500

（因此从NGINX获得

502坏网关

）

网址：

http://localhost/another.py

http://localhost/info.py

http://localhost/some.py

输出：

[pid: 9606|app: -1|req: -1/1] 127.0.0.1 () {42 vars in 624 bytes} [Fri Oct 18 15:40:50 2019] GET /another.py => generated 9 bytes in 0 msecs (HTTP/1.1 404) 2 headers in 71 bytes (0 switches on core 0)

很明显，它找到了文件（

info.py

和

some.py

），但uWSGI出现

500

错误的原因是什么？这两种配置是否都有问题

下面是一个Python脚本：

def application(environ, start_response):
    start_response('200 OK', [('Content-Type', 'text/html')])
    return [ "Ololo".encode("utf-8") ]

带有CGI插件的uWSGI通过以下方式安装：

我写了一封信，详细介绍了这件事

curl http://uwsgi.it/install | bash -s cgi /tmp/uwsgi
sudo mv /tmp/uwsgi /usr/bin
