本文web服务器使用的为apache。

1. 安装apache

yum install -y httpd

2. 配置apache

修改apache配置文件/etc/httpd/conf/httpd.conf将下面一行的注释去掉，如果没有则添加:
LoadModule cgid_module modules/mod_cgid.so

cgi脚本文件的默认路径为/var/www/cgi-bin/

修改如下几处内容:

<Directory />
AllowOverride none
Require all denied
</Directory>

为：

<Directory "/var/www/cgi-bin">
AllowOverride None
Options +ExecCGI
Order allow,deny
Allow from all
</Directory>

去掉注释并添加.py

AddHandler cgi-script .cgi .py

3.重启apache

第一、启动、终止、重启

systemctl start httpd.service #启动

systemctl stop httpd.service #停止

systemctl restart httpd.service #重启

第二、设置开机启动/关闭

systemctl enable httpd.service #开机启动

systemctl disable httpd.service #开机不启动

4.检查httpd状态

systemctl status httpd.service

● httpd.service - The Apache HTTP Server

5编写代码

#!/usr/bin/python
#coding=utf-8

print "Content-type:text/html"
print              #空行，告诉服务器结束头部
print '<html>'
print '<head>'
print '<meta charset="utf-8">'
print '<title>Hello Word - 我的第一个CGI程序！</title>'
print '</head>'
print '<body>'
print '<h2>嘿！ 你最帅了 ~</h2>'
print '</body>'
print '</html>'
