CentOS epel yum source tutorial

EPEL (Extra Packages for Enterprise Linux) is a Fedora-based project that provides additional software Packages for the Red Hat operating system, applicable to RHEL, CentOS, and Scientific Linux.

Easy to use:
1. First, we need to install a software package named "epel-release", which will automatically configure the yum software repository. Of course, you can also choose not to install this package, and configure the software warehouse by yourself.

# RHEL5 Series

wget http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
rpm -ivh epel-release-5-4.noarch.rpm

# RHEL6 Series

wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
rpm -ivh epel-release-6-5.noarch.rpm

2. After installation, you can directly use yum to install additional software packages.

yum clean all
yum install nginx pure-ftpd

Another more convenient way is to manually add the software repository configuration file.

vi /etc/yum.repos.d/epel.repo

[Epel]
Name = epel
Using list = http://mirrors.fedoraproject.org/mirrorlist? Repo = epel-$ releasever & arch = $ basearch

After adding:
