IMG 1010 - Installing Red Hat Linux on a Server

 

Before You Begin

Install Operating System Software per manufacturer's instructions. Below is a procedure on installing Red Hat Enterprise Linux. The procedure should be used as a guideline to installing the Linux OS. It should not be followed exactly since the installation changes with each version of Red Hat released.

As of 10.5.3 SP19, GCEMS now officially supports the following Operating Systems. 

  • Red Hat Linux 5.9, Tikanga, 32-bit

  • Red Hat Linux 6.7, Santiago, 64-bit

  • CentOS 7.3, 64-bit

Cacti is not supported in any GCEMS version of software earlier than version 10.5.0. 

Red Hat Enterprise Linux Installation:

  • Insert Linux Installation Disk 1. Reboot the machine. The CD will boot into a screen that will ask how you would like to install the OS. In this example the Graphical mode was selected. A welcome screen will appear select next.

  • The next few screens will configure language and Keyboard Type. Make selections accordingly.

  • The next screen will ask whether to install OS as a fresh installation or to update existing. In this example a fresh installation was chosen.

  • The hard drive needs to be configured. Either Automatic or Manual partitioning can be chosen. In this example manual partitioning was chosen. Below is the recommended partitioning scheme and hard drive sizes.

  • Once partitioning is finished then you will be asked whether to remove all partitions existing on drive. In this example removing all partitions was selected.

  • Configuring the Ethernet interfaces is accomplished next. In this example a static IP address was given to the machine. Uncheck "Configure using DHCPD". This will allow a hostname to be entered for the machine along with Default Gateway and Primary/Secondary/Tertiary DNS IP addresses.

  • Enable/Disable the firewall will be asked. Select accordingly. In this example the firewall was disabled.

  • If the firewall is enabled be sure to check the boxes for each service that you would like to allow access to. In this example all boxes were checked. Also remote access will be blocked if the firewall is enabled. See IMG 1010 - Configuring Remote Desktop for more information.

It is advisable that an external device manage your firewall

  • If you would like a warning each time a cookie etc is loaded select to enable SELinux. If not select to Disable SELinux. In this example it was disabled.

  • The next few screens ask about additional language support and Time Zone information. Make selections accordingly.

  • Root password will be configured next. We recommend that the root password be set to excel2. If support is needed then our support team will need this password if it is not given the default value of excel2.

  • The packages to be installed are the next piece to get configured. In this example the box at the bottom was chosen indicating all packages will get installed including packages that are not displayed. We recommend that you install everything so that all utilities are installed for troubleshooting, etc.

  • The OS will now get installed. The installation will prompt which disks to load at certain times. Installation will take approximately 60 minutes to complete.

  • Once all Linux packages are installed remove the disks and reboot the machine.

  • When the machine comes back after reboot you will be asked for a last basic configuration. Go through this configuration giving the following as the Linux user: username: excelsw password: excelsw  

  • The installation on Red Hat Enterprise Linux is complete. You can register your copy of Linux and install any updates. Located at bottom of Linux screen is a flashing red circle. Updates can be loaded from the Red Hat site by clicking on this red circle. See below.
