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:
-
/
-
File system type: EXT3
-
Set the size to 30000 MB
-
Force to be a primary partition
-
swap
-
File system type: swap
-
Generally, set the swap size to be twice the amount of RAM.
-
Force to be a primary partition
-
/export/home
-
File system type: EXT3
-
Use whatever space is left in the hard drive
Don’t force to be a primary partition
Make sure you have at least the 3 partitions above. Click “Next” to continue once you are satisfied with your partition configuration
-
Accept write changes to disc
-

Select “Minimal” in the default installation selection. Click on “Next” to continue.

The installation should now begin. At the end of the installation, you should receive a screen similar to the following:
-
Press the “Reboot” button.
-
Install the required RPMs for ReliaTel. To do so:
-
Upload the rpm-list.txt file below to the server.
-
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:
/etc/init.d/iptables stop
chkconfig iptables off
-
Disable SELinux. Edit the file “/etc/sysconfig/selinux”. Change the value of the parameter “SELINUX” to “disabled”:
# This file controls the state of SELinux on the system.
# 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.
SELINUXTYPE=targeted
-
Edit the file “/etc/hosts”. Enter the server’s IP address and hostname. For example:
192.168.19.102 dap-test.tonesoft.com
-
Reboot the server for the changes to take effect.
