How to Install Red Hat Enterprise Linux 5

 

to install Red hat Enterprise Server

you need to read the following

1. You need to put the DVD in your computer and boot the computer from that DVD.

2. Next the installer will offer you if you want to check the DVD media before installation. Choose skip here.

image

 

  • 3. Next you will see the first page of the Installation wizard. Press Next.
  • image

    4. Select the Language that will be used in the rest of the installation.

    image

    5. Select the keyboard type.

    image

  • 6. Next you will be asked to put your installation number. You may skip entering this number if you don't have one.

    7. Now you need to tell what do you want to do with your disk. I usually choose "Create custom layout" and create the partitions I need on the disk.

    image

    8. Here is our disk all free space if this is a fresh disk. This is a 30gb disk. Click "New" to create a partition.

    image

    9. First partition will be boot partition size 100m. This will allow the OS to keep the boot record on a separate partition.

    image

    10. The second partition will be /tmp. The size of /tmp depends upon the oracle database I am going to install e.g. Oracle 10g requires 400mb of space in /tmp and Oracle 11g requires at least 1gb. I will create /tmp with a size of 1.5gb.

    image

    11. Then comes the swap partition. The swap's size is dependent on the amount of physical RAM you have. I have 2G of RAM so the swap should be 1.5 times of 2G i.e. 3G. (This formula works for both Oracle 10g and 11g.)

    image

    12. The fourth partition will be /u01, a partition that will be used specifically for any thing. I am setting the size to 15gb.

    image

    13. The fifth partition is the "/" which is the root mount point for the operating system. We give it all the space left on the disk.

    image

    14. This is how your partitioning scheme should look like when you are done.

    image

    15. This screen will ask you if you want to keep the boot record on the disk or not. Keep the defaults and press next.

    image

    16. Here we will configure the network. Provide a hostname manually. Then click the Edit Button against Network Devices, disable the ipv6 and provide a static IP Address for IPv4. NO DHCP.

    image

    17. Click on the map to choose a region for your Time Zone.

    image

  • 18. Provide the password for the root (Administrator User in Linux) user.
  • image 19. Select the OS packages that you need. Mostly leaving it as default should be okay. But it is a nice idea to install some development packages which oracle may need while installation. Select "Customize now" and press Next.
  •  

    image

    20. All packages are listed. Right click on the package category and press "Select all optional packages" to install every thing in that category.

  • image

    21. Press next here, to start the installation.

  • image

    22. This will take several minutes, before the installation is complete. Once the installation is complete the system will reboot. Remove any media from DVD before the system restarts.

  • image

    23. After rebooting you will have to do some setup tasks. This is the Welcome page of the setup wizard. Press Next.

  • image

    24. Accept the license agreement and pres Next.

    image

    25. Disable the firewall and press Next.

    image

     

    26. Set SELinux "Disabled". If you leave it at "enforcing" you are gonna have trouble with oracle later for example you may not be able to start "sqlplus".

    image

    27. Leave kdump disabled.

     

    image

    28. Set the date and time.

     

    image

    29. Select to register at a later time.

    image

    30. If you have chosen not to register then this page shows that your system is not setup for Updates.

    image

    31. Use this page to create any additional users other then root.

    image

    32. Setup your sound card.

    image

    33. Use this page to install any additional software. Press Finish when done. The system will reboot again.

    image

    34. After reboot you will see the login screen. Login as root here using the password you provided during the install.

    image

    35. This is your RHEL 5 desktop. The installation is successful.
