1. Dalam mengupdate repository harus menambah atau mengupdate file “CentOS-Base.repo”. Anda harus terkoneksi dengan internet. Backup CentOS-Base.repo, caranya : [root@maxserver ~]#mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.asli

  2. Kemudian buat repository baru dengan nama CentOS-Base.repo.
    [root@maxserver ~]# vi /etc/yum.repos.d/CentOS-Base.repo


  3. Isi kan seperti berikut :
