Yum is the easiest tool to find and install packages on Red Hat/CentOS. However, yum needs to know where to look for packages. Here is where repositories come into play.
Of course, you always need to make sure the repositories you use are trusted! Installing packages from untrusted source can be pretty nasty since you basically give the RPM root priviledge on your machine.
Here are some trusted yum repositories that you can use:
Epel
- Red Hat 5 / CentOS 5
yum install http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
- Red Hat 6 / CentOS 6
yum install http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
RPMforge
Install the GPG key first:
rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
