Steps for Installing Linux

Now you can boot your PC from bootable CD or USB Key which we have seen in the last post. After a few lines are displayed, an RHEL Installation screen will appear with boot: prompt.
If you are installing from CD/DVD you can directly install in Graphical or Text mode. But, here we are going to see the third method Network Installation. So, at boot: prompt you have to type linux askmethod to start network installation.
Here is a step by step guide for the same:

1.    Boot your computer from the first RHEL CD, from a boot CD, or from a boot USB key.

2.    When you see the boot: prompt, enter the linux askmethod command. This temporarily starts the installation process in text mode (which is actually a low-resolution graphical mode)

3.    Select a language to use during the installation process. English is the default; nearly 50 options are available.

4.    Select a keyboard type; the default depends on the language you selected.

5.    Choose your installation method. Earlier in the post, I described how to configure an NFS installation server. Therefore, select the NFS image option (the steps for installing from FTP server vary slightly).

6.    Choose how you want IP addressing configured. Your options are to enable support as a DHCP client, for IPv4 and/or IPv6 addresses.

7.    If you enable DHCP, the installation looks for a DHCP server for IPv4 and/or IPv6 addresses. Otherwise, you'll  need to enter the information manually, along with appropriate gateway and nameserver (DNS) addresses.

8.    Direct your computer to the remote NFS server. Here you have to enter the host name or IP address of the NFS server, as well as the shared directory. (If you enter a host name, you'll need a working DNS server on your network.) If you set up an NFS installation server with the instructions earlier in the post, enter /install in the Red Hat Enterprise Linux Server Directory text box.

9.    If a proper connection is made, you'll see the first Red Hat Enterprise Linux graphical installation screen. Click Next to continue. Since you've already selected a keyboard type and language, RHEL skips those graphical screens that you'd otherwise see when installing from a CD/DVD.

    If you encounter problems, examine the third and fourth consoles; to do so, press ALT-F3 or ALT-F4.

    If you've installed Red Hat Enterprise Linux on this system before, you're given the chance to upgrade the existing installation.

    Once you complete the above mentioned steps, rest are self explenatory like Partition Screen, Boot Loader, Network Configuration, Time Zone Selection, Root Password and then finally Package Selection. All this will appear graphically. Be careful while creating partition, you should create 100MB /boot partition, swap partition will be double than your RAM and other space you can assign to your /(root) partition. It totally depends on you.
