Step 1 ：安装

sudo apt-get install fcgiwrap

Step 2 ：配置

文件路径配置

vim /etc/nginx/fcgiwrap.conf

location /cgi/ {
  gzip off;
  root  ${替换为你的代码文件目录};
  fastcgi_pass  unix:/var/run/fcgiwrap.socket;
  include /etc/nginx/fastcgi_params;
  fastcgi_param SCRIPT_FILENAME  ${替换为你的代码文件目录}$fastcgi_script_name;
}

nginx增加路径入口

vim /etc/nginx/sites-available/default

server {
    listen      80;
    server_name a.yeshen.org;

    include fcgiwrap.conf; # 新增配置
}

Step 3 ：简单demo

cd ${替换为你的代码文件目录}
vim test.py
chmod a+x test.py

test.py

#!/usr/bin/python
# -*- coding: UTF-8 -*-

print "Content-type:text/html"
print
print '<html>'
print '<head>'
print '<meta charset="utf-8">'
print '<title>Hello World</title>'
print '</head>'
print '<body>'
print '<h2>Hello World!</h2>'
print '</body>'
print '</html>'
