-bash: yum: command not found

Question

I have one server with Red Hat Enterprise Linux AS release 4 (Nahant Update 3) installed. And I tried to add the online repo using this link:

Centos Wiki: RPMForge

And everything goes smooth. But when I tried to install any package it replies:

[root@Backup yum.repos.d]# yum -v install httpd
-bash: yum: command not found

There are some repos in /etc/yum.repo.d/:

mirrors-rpmforge  mirrors-rpmforge-extras  mirrors-rpmforge-testing  rpmforge.repo

The content of rpmforge.repo is:

[root@Backup yum.repos.d]# cat rpmforge.repo
### Name: RPMforge RPM Repository for RHEL 4 - dag
### URL: http://rpmforge.net/
[rpmforge]
name = RHEL $releasever - RPMforge.net - dag

Solution 1

After simple checks I've asked you in answer comment:

[root@Backup yum.repos.d]# yum
-bash: yum: command not found
[root@Backup yum.repos.d]# which yum
/usr/bin/which: no yum in (/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin)
[root@Backup yum.repos.d]# echo $PATH
/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin
[root@Backup yum.repos.d]# rpm -q yum
package yum is not installed

we can verify that you don't have yum installed in your system.

Please install it via rpm and you'll be able to launch it.

Solution 2

1. Go to pkgs.org.
2. Find the yum rpm package for your rhel version and architecture (x86 or x86_64).
3. Download the rpm package.
4. Install with su -c 'rpm -i ~/Downloads/*.rpm or with your graphical package manager.

I added the information in Question Section

I have added the info in Question under Command Results. Seems like yum is not installed

[rush]

So you have to install it, and everything will be fine :)

[OmiPenguin]

Thanks for the information. So this is the reason. I never used rhel4 before so i had no idea about it. I started to learn from rhel5
