Install Node.js on CentOS 6 using yum

If you're running CentOS 6.x (I use 6.4 currently), and you have installed the EPEL yum repository, you can install Node.js simply with:

<br />
$ sudo yum install npm<br />

Done. Check for node's successful installation by running $ node -v (it should return something like v0.10.4).
