nodejs on centos

RHEL/CentOS/Scientific Linux 6

Node.js and npm are available from the Fedora Extra Packages for Enterprise Linux (EPEL)repository. If you haven't already done so, first enable EPEL.

To check if you have EPEL, run

 yum repolist

if you don't see epel, install it via RPM (At the time of this writing, the last version is 6.8.).

First import the key:

 sudo rpm --import https://fedoraproject.org/static/0608B895.txt

Then install

 sudo rpm -Uvh http://download-i2.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

And then run the following command to install node and npm:

 sudo yum install nodejs npm --enablerepo=epel

or if this doesn't work for you install node separately:

 sudo yum install npm --enablerepo=epel
