实践操作举例：
1.在RHEL上配置epel的yum源
这里有个epel的yum源地址：
链接下面有针对RHEL 4，5，6，7版本及不同架构的yum源。
操作系统中并没有EPEL安装源，我们可以通过下面的命令配置。
1.1 对于RHEL 5
# rpm -Uvh
执行命令后会在/etc/yum.repos.d下面创建两个yum源文件，分别是
epel-testing.repo epel.repo
1.2 对于RHEL 6
# rpm -Uvh
执行命令后会在/etc/yum.repos.d下面创建两个yum源文件，分别是
epel-testing.repo epel.repo
注意：RHEL 6的epel.repo源是有问题的，无法直接使用。
解决方法：
编辑 # vi epel.repo 文件，把https改成http
| [epel] name=Extra Packages for Enterprise Linux 6 - $basearch #baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch mirrorlist=http://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch failovermethod=priority enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

[epel-source] name=Extra Packages for Enterprise Linux 6 - $basearch - Source #baseurl=http://download.fedoraproject.org/pub/epel/6/SRPMS mirrorlist=http://mirrors.fedoraproject.org/metalink?repo=epel-source-6&arch=$basearch failovermethod=priority enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6 gpgcheck=1 |
保存立即生效
epel-testing.repo文件修改同上。
1.3 对于RHEL 7
安装epel的YUM源
# wget
# rpm -Uvh epel-release-7-6.noarch.rpm
# cat /etc/yum.repos.d/epel.repo
| [epel] name=Extra Packages for Enterprise Linux 7 - $basearch #baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch failovermethod=priority enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
[epel-debuginfo] name=Extra Packages for Enterprise Linux 7 - $basearch - Debug #baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch/debug mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-7&arch=$basearch failovermethod=priority enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 gpgcheck=1

2、部署rpmforge.repo的yum源
RedHat5
# wget http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.3-1.el5.rf.x86_64.rpm
RedHat6
# wget http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
# rpm -Uvh rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
RHEL7
# wget http://apt.sw.be/redhat/el7/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.3-1.el7.rf.x86_64.rpm
# rpm –Uvh rpmforge-release-0.5.3-1.el7.rf.x86_64.rpm
