1. 删除RHEL默认yum
# rpm -qa | grep yum
    yum-metadata-parser-1.1.2-16.el6.i686

    PackageKit-yum-0.5.8-21.el6.i686

    yum-3.2.29-40.el6.noarch

    yum-rhn-plugin-0.9.1-43.el6.noarch

    yum-plugin-security-1.1.30-14.el6.noarch

    yum-utils-1.1.30-14.el6.noarch

    PackageKit-yum-plugin-0.5.8-21.el6.i686

# rpm -e *yum* --nodeps      // 如果无法成功删除则分别手动删除

2. 下载并安装CentOS的yum
# cd ~/Downloads
# wget http://mirrors.sohu.com/centos/6.4/os/i386/Packages/yum-3.2.29-40.el6.centos.noarch.rpm
# wget http://mirrors.sohu.com/centos/6.4/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm
# wget http://mirrors.sohu.com/centos/6.4/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm 
# wget http://mirrors.sohu.com/centos/6.4/os/i386/Packages/yum-plugin-security-1.1.30-14.el6.noarch.rpm 
# wget http://mirrors.sohu.com/centos/6.4/os/i386/Packages/yum-utils-1.1.30-14.el6.noarch.rpm
# wget http://mirrors.sohu.com/centos/6.4/os/i386/Packages/PackageKit-yum-0.5.8-21.el6.i686.rpm
# wget http://mirrors.sohu.com/centos/6.4/os/i386/Packages/PackageKit-yum-plugin-0.5.8-21.el6.i686.rpm
# rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-metadata-parser-1.1.2-16.el6.i686.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm yum-plugin-security-1.1.30-14.el6.noarch.rpm yum-utils-1.1.30-14.el6.noarch.rpm 
# rpm -ivh PackageKit-yum-0.5.8-21.el6.i686.rpm PackageKit-yum-plugin-0.5.8-21.el6.i686.rpm

3. 添加镜像配置
# vi /etc/yum.repos.d/rhel-debuginfo.repo

输入如下内容：

[base]

name=Red Hat Enterprise Linux $releasever -Base

baseurl=http://mirrors.sohu.com/centos/6.4/os/$basearch/
gpgcheck=1

[update]

name=Red Hat Enterprise Linux $releasever -Updates

baseurl=http://mirrors.sohu.com/centos/6.4/updates/$basearch/
gpgcheck=1

[extras]

name=Red Hat Enterprise Linux $releasever -Extras

baseurl=http://mirrors.sohu.com/centos/6.4/extras/$basearch/
gpgcheck=1

4. 下载并导入KEY
# cd /etc/pki/rpm-gpg/
# wget http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-6
# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*
