Those great repositories are reliable and updated so I use them almost on every server I setup.
Add EPEL repository:
sudo yum update sudo yum install epel-release
Add REMI repository:
cd /etc/yum.repos.d sudo wget http://rpms.famillecollet.com/enterprise/remi-release-7.rpm sudo rpm -Uvh remi-release-7*.rpm
The REMI repository is disabled by default, so you have to edit and enable the aproppriate sections:
sudo vi /etc/yum.repos.d/remi.repo
Now run yum update and enjoy latest software from EPEL and REMI repository.
A big thanks to all contributors of EPEL and REMI repositories!
