i tried to install apt-get into my redhat server, but for some reason, yum was not installed automatically, so i had to install it manually. so the first thing i need to do is to make sure i have an internet connection and wget to do the following commands a root:

NOTE: If you have LInux Redhat Enterprise, You will NOT be able to install YUM without a License. So if you don't have one, you will need to buy one from Redhat. Otherwise, if you want to have YUM in your server, try an Open Source Distribution like Fedora.

change to your root directory:
CODE:
cd ~

Make a directory called yum (you can call it whatever you want)
CODE:
mkdir yum

change directory to the directory you just created (i used yum)
CODE:
cd yum

Download the yum version of your choice, i my case, i am downloading version 2.0.7 for my redhat Enterprise Edition Version 3
wget http://linux.duke.edu/projects/yum/download/2.0/yum-2.0.7.tar.gz

Untar the package
CODE:
tar xvzf yum-2.0.7.tar.gz

change directory to the directory you untar
CODE:
cd yum-2.0.7

run the configuration file
CODE:
./configure

make configuration
CODE:
make

make installation
CODE:
make install


that's it - it worked for me


before i could get this to work, i installed the latest, it turned out i was installing the wrong version for my python version, so make sure you are installing yum for the correct version: before, i kept getting this error whenever i tried the update command:
CODE:
