If you use CentOS and want to add some extra packages you can use EPEL.
Extra Packages for Enterprise Linux is project created by Fedora.
In order to use repositories on CentOS first download and install RPM appropriate for your version of CentOS from here:
Method 1
http://dl.fedoraproject.org/pub/epel/
- epel-release-latest-5.noarch.rpm – CentOS 5.x
- epel-release-latest-6.noarch.rpm – CentOS 6.x
- epel-release-latest-7.noarch.rpm – CentOS 7.x
Then install it and enjoy more packages from new repo.
Method 2
[root@localhost ~]# yum install epel-release
Here is example from CenOS 7 how to add EPEL repositories:
[root@localhost ~]# wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm --2015-05-24 08:52:36-- http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm Resolving dl.fedoraproject.org (dl.fedoraproject.org)... 209.132.181.24, 209.132.181.25, 209.132.181.26, ...
