1.下载需要的软件包
使用downloadonly命令下载需要的软件包（只下载不安装），将软件包保存到/rpm目录下：
[root@localhost ~]# mkdir -p /rpm
[root@localhost ~]# yum -y install yum-downloadonly
[root@localhost ~]# yum install --downloadonly --downloaddir=/rpm ntp net-snmp net-snmp-devel net-snmp-utils php-snmp expect mysql-devel mysql-server gcc-c++ make wget kvm libvirt python-virtinst scons ruby-devel ruby-docs ruby-ri flex bison xmlrpc-c-devel
2.挂载光盘将原光盘镜像内容同步
[root@localhost ~]# yum -y install createrepo mkisofs rsync
[root@localhost ~]# mkdir -p /data/OS
[root@localhost ~]# mkdir -p /mnt/cdrom
[root@localhost ~]# mount /dev/cdrom /mnt/cdrom
[root@localhost ~]# rsync -a /mnt/cdrom/* /data/OS/
[root@localhost ~]# cp /mnt/cdrom/.discinfo /data/OS/
3.将下载的软件包copy到Packages目录下
[root@localhost ~]#cp /mfs/* /data/OS/Packages/
4.配置kickstart脚本
[root@localhost ~]#vi /data/OS/isolinux/ks.cfg
# Kickstart file automatically generated by anaconda.
