一、编写python脚本，远程执行命令获取MD5校验码，脚本放到CGI路径下
1#!/usr/bin/env python 2 3#-*- coding: utf-8 -*- 4 5 6""" 7 8This runs a command on a remote host using SSH.

二、配置Apache调用python脚本
1开启CGI功能
2配置CGI路径，设置用户名验证方式
密码文件用Apache自带命令htpaddwd生成
给userA创建密码认证
htpaddwd /var/www/html/loganalyzer/passwd/.passwd userA
3报错解决
查看日志显示权限不足
chown apache.apache ssh.py
修改后成功访问
