原文の住所:http://www.if-not-true-then-false.com/2010/yum-remove-repo-repository-yum-disable-repo-repository/
Quick gide，howto remove and disable YUM repo.Yum command itself does not contain any way to remove the repository.YUM repo files is located in /etc/yum.repos.d/ directory.
I use kde.repo file with follwing content as example on thisガイド:

[kde]
name=kde
mirrorlist=http://apt.kde-redhat.org/apt/kde-redhat/fedora/mirrors-stable
gpgkey=http://apt.kde-redhat.org/apt/kde-redhat/kde-redhat.RPM-GPG-KEY
enabled=1

Remove YUM Repo(Repository)Permanently
Before moving repository permantly is a goodida to check that is the repository installed using rpm package.As many repos usualy are、like M-Fsion、Livna、etc.
Search Repository RPM-package with following command:

rpm -qa |grep -i repo-name

Example:

rpm -qa |grep -i rpmfusion
rpmfusion-nonfree-release-13-2.noarch
rpmfusion-free-release-13-2.noarch
 
## OR ##
 
rpm -qa |grep -i livna
livna-release-1-1.noarch

If RPM-package found then simply remove whole RPM-package with following command:

rpm -e some-repository-rpm-package

Example:

rpm -e livna-release-1-1.noarch

If RPM-package not found then simply remove repo file with following command:

rm /etc/yum.repos.d/repo-file.repo
 
## OR just rename it (without repo file extension) ##
mv /etc/yum.repos.d/repo-file.repo /etc/yum.repos.d/repo-file.repo.bak

Example:

rm /etc/yum.repos.d/kde.repo
 
## OR just rename it (without repo file extension) ##
mv /etc/yum.repos.d/kde.repo /etc/yum.repos.d/kde.repo.bak

Discable YUM Repo(Repository)
Displale YUM Repo
Edit repo file on/etc/yum.repos.d/as root and change enabled to 0

## Change
enabled=1
 
## To
enabled=0

Example:

# Change
[kde]
name=kde
mirrorlist=http://apt.kde-redhat.org/apt/kde-redhat/fedora/mirrors-stable
gpgkey=http://apt.kde-redhat.org/apt/kde-redhat/kde-redhat.RPM-GPG-KEY
enabled=1
 
# To
[kde]
name=kde
mirrorlist=http://apt.kde-redhat.org/apt/kde-redhat/fedora/mirrors-stable
gpgkey=http://apt.kde-redhat.org/apt/kde-redhat/kde-redhat.RPM-GPG-KEY
enabled=0

Enbale disabled repo quickly with YUM：

yum --enablerepo=some-disabled-repository install some-package

Discable YUM Repo(Repository)using YUM

yum --disablerepo=some-repository install some-package

Example:

yum --disablerepo=kde install some-package
