Add Additional YUM Repository to Redhat EL5

在標準的 Redhat EL5 底下，yum 的 repository 只提供官方的版本。日前，因為工作需要要裝以下的 library or package 給 PHP 使用，

pecl/json
pecl/imagick

可是在官方版本底下，找不到相關的套件；嘗試用 'pecl install imagick' 重新編譯時，又會發生找不到 libWand.so 相關的函式庫。在網路上 google 了一番，發現在 EPEL(Extra Package for Enterprise Linux) 有現在的 rpm 可用，所以就試著把它裝起來，以下是所有的步驟。

--------------------------------------------------------------------
Add the following two files into '''/etc/yum.repos.d'''

filename: /etc/yum.repos.d/epel.repo

[epel]

name=Extra Packages for Enterprise Linux 5 - $basearch

#baseurl=http://download.fedoraproject.org/pub/epel/5/$basearch

mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=epel-5&arch=$basearch

failovermethod=priority

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL

[epel-debuginfo]

name=Extra Packages for Enterprise Linux 5 - $basearch - Debug

#baseurl=http://download.fedoraproject.org/pub/epel/5/$basearch/debug

mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=epel-debug-5&arch=$basearch

failovermethod=priority

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL

gpgcheck=1

[epel-source]

name=Extra Packages for Enterprise Linux 5 - $basearch - Source

#baseurl=http://download.fedoraproject.org/pub/epel/5/SRPMS

mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=epel-source-5&arch=$basearch

failovermethod=priority

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL

gpgcheck=1

filename: /etc/yum.repos.d/epel-testing.repo

[epel-testing]

name=Extra Packages for Enterprise Linux 5 - Testing - $basearch

#baseurl=http://download.fedoraproject.org/pub/epel/testing/5/$basearch

mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=testing-epel5&arch=$basearch

failovermethod=priority

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL

[epel-testing-debuginfo]

name=Extra Packages for Enterprise Linux 5 - Testing - $basearch - Debug

#baseurl=http://download.fedoraproject.org/pub/epel/testing/5/$basearch/debug

mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=testing-debug-epel5&arch=$basearch

failovermethod=priority

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL

gpgcheck=1

[epel-testing-source]

name=Extra Packages for Enterprise Linux 5 - Testing - $basearch - Source

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL

gpgcheck=1

Also you need to import the gpg key for the repository as follows: (check out latest location of file: https://fedoraproject.org/keys)

$ cd /etc/pki/rpm-gpg

$[/etc/pki/rpm-gpg] wget -o RPM-GPG-KEY-EPEL https://fedoraproject.org/static/217521F6.txt

$[/etc/pki/rpm-gpg] sudo rpm -import RPM-GPG-KEY-EPEL
