Python 2 与 Apache CGI 实验

web选型

web服务器首选nginx，但nginx不支持cgi，因为太古老了

所以选用apache

主要为理解cgi的模式流程
理解header的作用

apache的安装

原本想使用ubunt系统，但对配置文件路径不熟悉，作罢

Yum 安装

yum install -y httpd

配置

apache的配置文件为/etc/httpd/conf/httpd.conf

文件需要修改根目录

将目录替换
<Directory />
  AllowOverride none
  Require all denied
</Directory>
为：
<Directory "/var/www/cgi-bin">
  AllowOverride None
  Options +ExecCGI
  Order allow,deny
  Allow from all
</Directory>

修改增加 AddHandler

去掉注释

代码

将注释去掉，并增加.py 后缀
AddHandler cgi-script .cgi .py

重启apache

systemctl start httpd.service #启动
systemctl stop httpd.service #停止
systemctl restart httpd.service #重启

检查httpd状态

#!/usr/bin/python

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！ this is cgi!~</h2>'
print '</body>'
print '</html>'

增加权限

Bash

1

chmod 755 /var/www/cgi-bin/hello.py

测试结果

在当前服务器上使用命令

curl localhost/cgi-bin/hello.py

结果成功
