   After configuring, yum.conf file should look similar to the code below.
   
   

   Code:
   [main]
   cachedir=/var/cache/yum

   distroverpkg=redhat-release
   tolerant=1
   exactarch=1
   obsoletes=1
   # PUT YOUR REPOS HERE OR IN separate files named file.repo
   # in /etc/yum.repos.d
   #[base]
   #name=RedHat Enterprice Linux ES 3 - Base
   #baseurl=http://yummie/RHEL3/es/base
   #gpgcheck=0
    
   #[update_3]
   #name=RedHat Enterprice Linux ES 3 - Update3
   #baseurl=http://yummie/RHEL3/es/update3
   #gpgcheck=0
   
   #[update_4]
   #name=RedHat Enterprice Linux ES 3 - Update4
   #baseurl=http://yummie/RHEL3/es/update4
   #gpgcheck=0
   
   #[update_5]

   baseurl=http://yummie/mrepo/rhel4.6-es-x86_64/RPMS.os/
   gpgcheck=0

   
   
4. Modify the entry to point to the repository that is being updated. In the example below, the system is being updated to Redhat 5.6.
   
   

   Code:
   [update_6]
   name=RedHat Enterprise Linux ES 5 - Update_6
   baseurl=http://yummie/mrepo/rhel5.6-$basearch/RPMS.os/
   gpgcheck=0

   
   
5. Save the file and test it to see if Yum is working.
   
   

   Code:
   [root@6007linux ~]# yum update
