This document provides step-by-step instructions for installing CentOS or Red Hat Linux for a ReliaTel remote DAP or a ReliaTel application server, including the required packages/rpms. CentOS will be used in the steps below; however, the process is very similar for Red Hat.
Choose CentOS/Red Hat 6.3 64-bit (x86_64) OS for the Installation.
Boot from the CentOS/ Red Hat 6.3 DVD/ISO image.
Select the Install option “Install or upgrade an existing system”.
Review and modify partitioning layout. You will need to create 3 partitions: / , swap, and /export/home. Select Standard Partition for each partition.
Configurations will vary depending on the size and amount of hard drives available in the system. Initially, you should have a blank hard drive.
To create a new partition, click “create”, select the mount point, specify the size and choose whether it should be forced to be a primary partition or not. Following is an example for the / (root) partition:
Use the following settings to create the three partitions:
From the server’s command line, as the ‘root’ user, run the following command from the same directory where the text file above was uploaded:
yum -y install $(cat rpm-list.txt)
This will install all RPMs in the attached document. This installation may take a few minutes to complete. Verify that there are no errors at the end of the installation.
Stop and disable firewall from automatically starting after reboot. Run the following commands:
chkconfig iptables off
Disable SELinux. Edit the file “/etc/sysconfig/selinux”. Change the value of the parameter “SELINUX” to “disabled”:

# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled # SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
Edit the file “/etc/hosts”. Enter the server’s IP address and hostname. For example:
