Installing YUM is easy but considering you are newbie, may sound little complicated.. just follow the steps:

First we need to download yum and install.
Do as :

Code: [Select]

wget http://yum.baseurl.org/download/3.2/yum-3.2.22.tar.gz
tar -xvzf yum-3.2.22.tar.gz
cd yum-3.2.22
./configure
make
make install
Execute above one by one .

Now need to configure it :
For that open /etc/yum.conf and do the changes as described below.

Code: [Select]


[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1

[base]
name=CentOS-$releasever - Base
baseurl=http://mirror.centos.org/centos/5/os/i386/
gpgcheck=1

[updates]
name=Red Hat Linux $releasever - Updates
baseurl=http://mirror.centos.org/centos/5/updates/i386/
gpgcheck=1

Now we need to have GPG keys (kind of security check for RPM downloads)

Code: [Select]

rpm --import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
Now try to run YUM and should work !

Btw, for cd mount..

Code: [Select]

mount /dev/cdrom
Above should work as your /etc/fstab must already have required entry for your cd drive.

Hi,

How to mount cdrom:

>mount /media/cdrom
or
Syntax:mount <device> <mount point>
>mount /dev/cdrom /root/xyz
or

1.Check where /media is present whether SATA or PATA,If SATA
If Hard disk is sda,sdb etc then
>ls /dev/sd*
/dev/sda /dev/sda1
else
>ls /dev/hd*
/dev/hdc

2.Lets assume it is /dev/hdc
If cdrom dir is not present then
>mkdir /media/cdrom 
>mount /dev/hdc /media/cdrom
>cd /media/cdrom
>ls

You will be able to view all packages.Make a directory in any location and copy all packages there.

Yum Install

>cd /etc/yum.repos.d
>vim server.repo
(please type the following lines in this file)
[MyRepository]
name=repository
baseurl=http://server1.ex.com/pub/Server (please mention the path on the server where packages are kept)
enabled=1
gpgcheck=0

:wq(save file)

>yum clean all
>cd ~
>yum install <package name>

The above procedure should work

With Regards
