This was a simple shell script I made to install EPEL and REMI yum repos. I have installed so many CentOS machines that I get tired of running the same commands over and over so I made this a script. Run `curl https://gist.githubusercontent.com/Justasic/9855295/raw/install.sh | sh` to install.

install.sh

#!/bin/sh

# Install yum priorities to make sure we aren't going to try and install fedora on centos :s
yum install yum-priorities -y

# Import the GPG keys for package verification signatures
rpm --import https://fedoraproject.org/static/0608B895.txt
rpm --import http://rpms.famillecollet.com/RPM-GPG-KEY-remi

# Install epel and remi repos
rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

mv /etc/yum.repos.d/epel.repo.tmp /etc/yum.repos.d/epel.repo

sed -e '/\[remi\]/{n;n;n;n;s/enabled\=0/enabled\=1/' -e '}' /etc/yum.repos.d/remi.repo > /etc/yum.repos.d/remi.repo.tmp

mv /etc/yum.repos.d/remi.repo.tmp /etc/yum.repos.d/remi.repo

# Update yum
yum update -y

#finished
echo "EPEL and REMI Repositories installed."
