我们在安装最新的红帽7.0和Centos 7.0以及Oracle Linux 7.0的时候，一般是使用光盘来安装。当服务器没有光驱的时候，我们往往需要通过dd直写U盘来实现，比较不灵活。为了扩充我之前的U盘系统 如何制作一个通用的多系统安装U盘 ，特别添加了红帽系列系统的最新版 7.0。同样也适用于Centos 7.0和Oracle Linux 7.0。下面来看一下制作步骤。
工具准备：
SYSLINUX #最新版是6.03
添加主配置文件：
请参考 如何制作一个通用的多系统安装U盘五(制作主配置文件）
以及 如何制作一个通用的多系统安装U盘六(Linux相关配置）
在/boot/config/linux.cfg 中添加
label redhat70x64 menu label Install Redhat Enterprise Server 7.0 64Bit kernel /boot/syslinux/vesamenu.c32 append /boot/linux/rh7064/isolinux.cfg /boot/config/mainmenu.cfg
拷贝文件：
拷贝ISO中的isolinux目录和images目录内容到U盘相应目录。我这里是/boot/linux/rh7064。
修改/boot/linux/rh7064/isolinux.cfg文件

其实，红帽7的ISO和之前的6.x相似，只是经过了一个特殊的处理。添加了
inst.stage2=hd:LABEL=RHEL-7.0\x20Server.x86_64
标签。inst.stage2是指定 install.img 的路径的。如果没有指定的话，Anaconda会从本地、inst.repo或repo或method参数给出的路径来查找。而且新版的7.0已经不推荐使用method参数了，代替method的是repo或inst.repo参数。所以，我们只要用repo或inst.repo来取代inst.stage2就可以了。最后，预祝大家都能够成功。
