The CentOS version I use here is the latest version of the 2.8 that 6.6,xcat uses. In addition, in order to illustrate the convenience of installation of the entire use of root users.
Download the Xcat offline package first
wget http://sourceforge.net/projects/xcat/files/xcat/2.8.x_Linux/xcat-core-2.8.5.tar.bz2/download
wget http ://sourceforge.net/projects/xcat/files/xcat-dep/2.x_linux/xcat-dep-201502061114.tar.bz2/download
Unpack the installation package
Tar jxvf xcat-core-2.8.5.tar.bz2
tar jxvf xcat-dep-201502061114.tar.bz2
Create Xcat local Yum Warehouse
cd/root/xcat-dep/rh6/x86_64;/mklocalrepo.sh
Cd/root/xcat-core;/mklocalrepo.sh
Once created, two Yum warehouse files are generated in the/ETC/YUM.REPOS.D directory Xcat-core.repo and Xcat-dep.repo
Install Xcat
Yum Clean metadata
yum install-y XCAT
Check if Xcat is properly installed
source/etc/profile.d/xcat.sh
tabdump Site
Installing the Xcat UI
Yum install-y php
yum install-y xcat-ui-deps yum install-y xcat-ui
Then access Http://<xcat_host>/xcat and use Linux user root to log on to the system.
