1. Download EPEL RPM
[[email protected] yum.repos.d]# wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-2.noarch.rpm --2014-10-01 00:27:11-- http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-2.noarch.rpm Resolving dl.fedoraproject.org (dl.fedoraproject.org)... 209.132.181.24, 209.132.181.23, 209.132.181.25, ...

2. Install RPM
[[email protected] yum.repos.d]# rpm -ivh epel-release-7-2.noarch.rpm warning: epel-release-7-2.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID 352c64e5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:epel-release-7-2 ################################# [100%] [[email protected] yum.repos.d]# [[email protected] yum.repos.d]# ll total 44 -rw-r--r--. 1 root root 13104 Oct 1 00:27 epel-release-7-2.noarch.rpm -rw-r--r--. 1 root root 957 Sep 2 12:14 epel.repo <<< -rw-r--r--. 1 root root 1056 Sep 2 12:14 epel-testing.repo <<< -rw-r--r--. 1 root root 76 Sep 28 02:25 frank.repo
3. After verify EPEL, found follow alarm:
[[email protected] yum.repos.d]# yum repolist Loaded plugins: fastestmirror, langpacks frank-repo One of the configured repositories failed (Unknown), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Disable the repository, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable 4. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=.skip_if_unavailable=true Cannot retrieve metalink for repository: epel/x86_64. Please verify its path and try again
4. Edit EPEL.repo and workaround it
Remove not enable repo
Use baseurl, not mirrorlist, that should root reason.
Set priority is 10, CD repo’s priority is 1
[[email protected] yum.repos.d]# vim epel.repo[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 [epel-source] name=Extra Packages for Enterprise Linux 7 - $basearch - Source #baseurl=http://download.fedoraproject.org/pub/epel/7/SRPMS mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-source-7&arch=$basearch failovermethod=priority enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7[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 priority=10 enabled=1 gpgcheck=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
5. Verify again:
