Use Public Yum Server for Oracle Linux

There is no yum repository in Oracle Linux after installation,
so it's necessarry to set it in order to update the system with yum command.
Oracle provides public yum server and we can use it for free to set.
⇒ Public Yum Server : http://public-yum.oracle.com/

Download repository like follows. (The example below is for Oracle Linux 6)


[root@dlp ~]# cd /etc/yum.repos.d
[root@dlp ~]# wget http://public-yum.oracle.com/public-yum-ol6.repo
