Centos installation

In order to install MOR you need Centos 5.2+ system (Install current version Centos 5.4).

First of all you need to download install image. Decide which architecture you need: i386 or x86_64 and download only 1st CD out of 6(7). Because only first CD is necessary to install base system.

How to choose between i386 (32bit) and x86_64 (64bit)? Simple rule: if you have 4gb of RAM or more - choose x86_64 (64bit).

Centos can be downloaded from here: http://mirror.centos.org/centos/5/isos/

As an example for i386 you should download file CentOS-5.4-i386-bin-1of6.iso

And for x86_64 file CentOS-5.4-x86_64-bin-1of7.iso

Make sure file IS NOT LiveCD and extension is ISO, but not .torrent!

After you burn and boot from this CD, you will see:

Press ENTER here to go to GRAPHICAL MODE (in text mode it is not possible to deselect all the packets).

After that you will be asked to test install CD - let's skip this part to save time:

On main Centos window press NEXT:

Select your installation language:

And keyboard layout:

Then your system asks you to reformat your HDD, make sure you know what you are doing and press YES:

Then installer asks if new HDD layout is ok - you can change it if you know what you are doing - we recommend to leave it as it is, press NEXT:

In next window confirm your step by pressing YES:

Following window lets you select network configuration, enter manual details or leave DHCP (manual is recommended):

Select your time-zone:

Enter root password:

This step is VERY IMPORTANT! Make sure you unchecked EVERYTHING from package selection, and CHECK "Customize now", press NEXT:

This step is also VERY IMPORTANT! Make sure you unchecked EVERYTHING again and in ALL categories! Nothing should be left selected - otherwise installed will ask you for other install CDs. When done press NEXT:

Then you will see final window after which installation begins (press NEXT):

Troubleshooting

If installation is asking you for CD #2, #3, #4 or anything else - that means you failed to UNSELECT all packets as was pointed out before.

Solution:

1. Read manual carefully once again
2. Do as it says EXACTLY (unselect ALL packets)
3. Reinstall
