In the absence of a CD-ROM, you need to install the package, you will use a common network of Yum source to install.
RedHat Linux is installed by default, Yum software, but because of the reason for the activation of the authentication RedHat can not directly do yum install some software, if we need to install the software under the RedHat yum, we only use the source of Yum to change to CentOS is good, Then change all the variables in the source to the actual values so that you can use Yum to install the software we need directly.
