复制代码

下面解释一下大概的意思
先检测 /root目录下面有没有文件名为xiaosu.cfg的kickstart配置文件

然后安装制作ISO包和yum的插件还有创建yum源数据库的包

备份原来的yum配置文件

将163的源写入配置文件

创建目录

用wget从sohu的镜像源上下载ISO文件中必须的一些文件（比如initrd文件，install.img）

生成一个临时的yum配置文件

从kickstart配置文件中读取需要安装的包，然后用一个for循环遍历安装

恢复原来的配置文件

生成ISO中必须的文本文件.treeinfo 和 .discinfo

将kickstart的配置文件复制到光盘目录

用sed取消掉原来的默认选项然后追加一个自动安装的选项（如刚才那个图片所示，开机之后，自动将光标停留在自动安装的选项上）

重新生成yum源的数据库

生成ISO文件，并放到/root目录下
