Create local metadata resource of yum

Today, I need install an oracle software for a machine whose os is Linux.

As we all know, installing oracle database software need installing additional packages. In order to install these package easily, i create a local yum resource.

As following:

We only assume that mount cdrom to media
/dev/hdc              3.3G  3.3G     0 100% /media

mkdir /yum
cp -r /media/* /yum

install tool package:
[root@test ~]# rpm -ivh /yum/Server/createrepo-0.4.11-3.el5.noarch.rpm
warning: /yum/Server/createrepo-0.4.11-3.el5.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

Lastly, editor the local repos file
