利用shell脚本做可执行安装程序

利用shell脚本制作可执行安装程序

制作简单的安装包的时候可以简单的用cat命令连接两个文件，然后头部是脚本文件，执行的时候把下面的文件分解出来就行了。一般这个后部分的文件是 个压缩包，那样，就能够打包很多文件了，在脚本中解压出来即可。这就是Linux那些bin、run等安装脚本的简单制作了。

如在linux 下制作二进制 .bin 文件的制做方法：就是使用cat 命令将执行脚本和打包文件同时放到一个.bin的文件里。这样安装的时候只要使用一个包，直接执行该包即可安装完毕，简单方便。

下例就是一名为脚本，它实现以下功能：

 自动创建用户及用户组

 自动检查网络环境并安装环境包所需要的支撑环境

 显示安装进度

 自动检查并配置防火墙

 自动安装环境包

 自动增加自启动脚本

1. bin文件制作步骤

a) 打包文件

tar cvf

b) 编写脚本

内容见《脚本内容》节

c) 可执行安装程序制作方法

# cat

>

这样就生成的安装文件，该文件是由shell脚本和二进制合成的。前半部分是脚本后半部分是二进制文件，用strings等 二进制查看命令可以看到。

2. 安装

chmod 755

./

3. 脚本内容
