Linux Yum installs Perl with local CD source

Reference: http://hi.baidu.com/pengduo66/item/abfe454f81cdb7e5a4c06675

Scenario Description: Choose to minimize the installation of the Linux operating system without the Perl tools installed. Because of network failure, you cannot install Perl from the Internet using Yum install Perl, only the original installation CD. Then try using the local CD as the installation source.

Step 1: Create a disc mount point

Mkdir/iso

Step 2: Mount the disc image

Mount-o Loop/centos-6.5-x86_64-bin-dvd1.iso/iso

Step 3: Set/etc/yum.repos.d/centos-media.repo, Fundamentals Specify the mount point of the disc

# Centos-media.repo

#Description, the source can use the mounted DVD source to specify a mount point. You can use this source to take advantage of Yum

#Install software directly from the CD image
# This repo can is used with mounted DVD media, verify the mount point for

# CentOS-6. You can use this repo and yum to install items directly off the

# DVD ISO that we release.

#Explanation: In order to use this source, you must connect to the DVD and use the following instructions:

# yum--enablerepo = c6-media Install XXXX

# To use this repo, put on your DVD and use it with the other repos too:

# yum--enablerepo = c6-media [command]

#Explanation: If you only want or can only use the media installation source, you must use the following command:

# yum--disablerepo = \ *-enablerepo = c6-media Install Perl

# or for the media repo, does this:

#

# yum--disablerepo = \ *-enablerepo = c6-media [command]

[C6-media]
name = centos- $ releasever-media

Step 5: Detailed description and reference documentation are different

The reference document uses: C5-media and we are using C6-media, because the centos6.4 version is used.

The following error often occurs when using Yum for install
warning:rpmts_HdrFromFdno:Header V3 DSA signature:nokey, key ID 1ac70ce6
causes the installation to fail. Here's how to fix it:

[email protected] centos]# rpm--import/etc/pki/rpm-gpg/rpm-gpg-key-beta
