Python implements a one-click installation Deployment LNMP Environment

Recently has been learning python, things more, time continues to be longer, in order to be able to learn, think of the original shell one-click installation Deployment Lnmp script, since the shell can write, Python will also be able to write, with the knowledge to write the following version, This may not be the optimal version, so when you learn more things, you can optimize and upgrade!

Environment Introduction:

Python 2.6.6

Centos 6.5

Nginx 1.10.1

MySQL 5.6.34

PHP 5.3.3

The code is as follows:

#!/bin/env python

Import OS

Import Sys

def enter (i): #定义一个函数, pass a parameter as the counter

Info= ' #定义开头显示的提示选择信息

-----Select Install Option-----

1.Install Nginx-1.10.1

2.Install Mysql-5.5.6.34

3.Install PHP-5.3.3

4.Install Required Components #安装必备组件

5.Exit Program
