I've run into issue. I have a python script. You can call it CGI script. It works fine under Apache2, but is only one left before I shutdown system it runs forever. New system uses nginx. I've configured uwsgi as suggested by many while searching on solution, configured virtual host for this script to run. I've used first example on uwsgi wiki to confirm I have properly configured nginx and it can communicate with uwsgi. Worked like charm.
Now my complications:
My script was written some time ago and is not designed for WSGI, nor I want/can rewrite it.
So I've installed cgi module for uwsgi and tried using it. All I get is 502 errors. Nothing being executed uwsgi.
Here is my config I'm using for this app:
[uwsgi]
plugins = cgi
socket = 127.0.0.1:9010
cgi = /=/usr/share/test/
cgi-allowed-ext = .py
cgi-helper = .py=python
Here is code I have in index.py (test script):
#!/usr/bin/python
print "Content-type: text/html\n\n"
print "<html><body><h1>It works!</h1></body></html>"
I try to test uwsgi with following command:
/usr/sbin/uwsgi --http :9011 --ini /etc/uwsgi/test.ini --master
And here is output I get:
[uWSGI] getting INI configuration from /etc/uwsgi/test.ini

Where is problem? Please help.
Thanks in advance.

Nginx doesn't have native CGI support (it supports fastCGI instead). The typical solution for this is to run your Perl script as a fastCGI process and edit the nginx config file to re-direct requests to the fastCGI process. This is quite a complex solution if all you want to do is run a CGI script.
Nginx is “a web server which can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache”. uWSGI is an implementation of the WSGI spec, which describes how a web server should communicate with a web app, which makes uWSGI also a type of web server.
Nginx natively includes support for upstream serversupstream serversIn computer networking, upstream server refers to a server that provides service to another server. In other words, upstream server is a server that is located higher in a hierarchy of servers.https://en.wikipedia.org › wiki › Upstream_serverUpstream server - Wikipedia speaking the uwsgi protocol since version 0.8.
Ok. I didn't read uwsgi WIKI good enough. All I had to do, is add --http-modifier1 9 to the command line switch, or uwsgi_modifier1 9; to nginx config.
location / {
include /etc/nginx/uwsgi_params;
uwsgi_modifier1 9;
uwsgi_pass 127.0.0.1:9010;
}
/usr/sbin/uwsgi --http :9011 --http-modifier1 9 --ini /etc/uwsgi/test.ini --master
