接下来准备ksdir目录下的安装引导文件ks#.cfg。ks#.cfg文件的获取方法有两种，一种是通过工具来生成。不过这个工具需要自己安装：
[ root@vinsent ~ ]#yum install -y system-config-kickstart
[ root@vinsent ~ ]#system-config-kickstart
另外这一种是复制/root目录下的anaconda-ks.cfg文件加以修改。我们选择后者。
[ root@vinsent html ]#cp /root/anaconda-ks.cfg ksdir/ks7.cfg
[ root@vinsent html ]#vim ksdir/ks7.cfg
....
[ root@vinsent html ]#chmod +r ksdir/ks7.cfg # "这里的文件需要加读权限，非常重要"
[ root@vinsent html ]#cat ksdir/ks7.cfg # centos 7的kickstart文件
