In this post, I will guide you on how to install or update the Redhat RPM packages from mounted local CDROM. Assume that you want to install the Redhat 5 packages. Please follow below steps:
1. Mount the CDROM media.
[root@server ~]# mount /dev/hdc /media
2. Create local.repo in yum.repos.d
[root@server ~]# cd /etc/yum.repos.d [root@server yum.repos.d]# vi local.repos
[RHEL-5-Repository] name=RHEL5 repository baseurl=file:///media/Server enabled=1 gpgcheck=0
3. Save and you can start install or update using yum command.
