4.6 导入系统镜像
4.6.1 上传ISO镜像至服务器
注意下载的ISO文件要核对文件的md5值，确保数据完整性
[root@hxinstall x86_64]# md5sum CentOS-5.8-x86_64-bin-DVD-1of2.iso
8a3bf0030f192022943f83fe6b2cf373 CentOS-5.8-x86_64-bin-DVD-1of2.iso
4.6.2 创建ISO目录
mkdir -p /var/iso/Linux/Centos/x86_64/
mkdir -p /var/os/Linux/Centos/x86_64/Centos5.8/dvd
mkdir -p /var/os/Linux/Centos/x86_64/Centos6.3/dvd
mkdir -p /var/os/Linux/Centos/x86_64/Centos6.4/dvd
4.6.3 挂载ISO镜像
mount -o loop /var/iso/Linux/Centos/x86_64/CentOS-5.8-x86_64-bin-DVD-1of2.iso /var/os/Linux/Centos/x86_64/Centos5.8/dvd
4.6.4 从DVD中导入OS数据
系统版本命名为centos5.8 架构x86_64，这时间长，耐性等待。可查看ls /var/www/cobbler/ks_mirror/centos5.8-x86_64/目录文件生成情况。
cobbler import --path=/var/os/Linux/Centos/x86_64/Centos5.8/dvd --name=centos5.8 --arch=x86_64

cobbler import --path=/var/os/Linux/Centos/x86_64/Centos6.4/dvd/ --name=centos6.4 --arch=x86_64
4.7 删除导入的系统
cobbler profile find --distro=centos6.3-x64-x86_64 #
查看配置是否存在
centos6.3-x64-x86_64
cobbler profile remove --name=centos6.3-x64-x86_64 #
删除配置文件
cobbler distro remove --name=centos6.3-x64-x86_64 #
删除distro
cobbler profile find --distro=centos6.3-x64-x86_64 #
再查看配置已无
