When we install the latest Red Hat 7.0 and Centos 7.0 and Oracle Linux 7.0, we generally use CDs to install them. When the server does not have an optical drive, we often need to write directly to the USB flash drive through dd, which is not very flexible. To augment the previous USB flash drive (see: How to make a universal multi-system USB flash drive), I specifically added the latest version of Red Hat series 7.0, which also works with Centos 7.0 and Oracle Linux 7.0. Let's take a look at the production steps below.

Tool preparation:

SYSLINUX #latest version is 6.03

Add Master Profile:

Please refer to how to make a universal multi-system installation USB flash drive V (making the main configuration file)

And how to make a universal multi-system installation USB flash drive six (Linux-related configuration)

Add to/boot/config/linux.cfg

label redhat70x64menu label Install Redhat Enterprise Server 7.0 64Bitkernel /boot/syslinux/vesamenu.c32append /boot/linux/rh7064/isolinux.cfg /boot/config/mainmenu.cfg

Copy files:

Copy the contents of isolinux directory and p_w_picpaths directory in ISO to the corresponding directory of USB flash drive. I have/boot/linux/rh7064 here.

Modify the/boot/linux/rh7064/isolinux.cfg file

Note: Please refer to the previous series of articles for the specific meaning of parameters.

In fact, Red Hat 7's ISO is similar to the previous 6.x, but with a special treatment. added

inst.stage2=hd:LABEL=RHEL-7.0\x20Server.x86_64

Labels. inst.stage2 is the path that specifies install.img. If not specified, Anaconda looks up the path given by the local, inst.repo, or repo or method parameters. In addition, the new version 7.0 no longer recommends using method parameters, instead of repo or inst.repo parameters. So, we just replace inst.stage2 with repo or inst.repo. Finally, I wish you all success.
