About this task

The default values provided for the Red Hat Enterprise Linux Server installation are suitable from an Experience Portal perspective. However, there are instances where you must select values other than the default. The following steps are guidelines to installing Red Hat Enterprise Linux Server and provide instructions for instances when the default values are not suitable for Experience Portal.

Before you begin

Have the completed Single server configuration worksheet ready to help answer the questions raised during the installation.

Procedure

The system displays the Welcome to Red Hat Enterprise Linux screen.
Select the Install Red Hat Enterprise Linux option.
Select English as the language to use during the installation process.
Select the U.S. English keyboard option.
Select Installation Destination and select the disk to install Red Hat Enterprise Linux..
Select Network and Host name.
Enter the host name and select Apply.

Note:

All network configuration including the hostname and IP (and other properties specified in steps 7 and 8) must remain the same.
To configure the network:
1. Ensure that eth0/ens192, the main Ethernet interface, is enabled.

  After the Experience Portal software is installed, use a non-root account to log in and then change to root account by using the su — command.
4. Disable the firewall.
5. Set default umask to 027 in the /etc/profile and /etc/bashrc scripts.
6. Configure a yum repository that has required Experience Portal packages.
Configure Avaya Secure Access Link (SAL) or the Enhanced Access Security Gateway (EASG) solution if you have purchased a maintenance agreement with Avaya services, and the server is the Primary EPM server.
