You can determine the CPU architecture of your server with these commands:
$ getconf LONG_BIT
64
$ uname -p
x86_64
You can download this file from the browser or from the console. The latter is shown below (Note: the specific Node.js version might be different for you):
$ wget http://nodejs.org/dist/v0.12.0/node-v0.12.0-linux-x64.tar.gz
From a console window, go to the directory to which the Node.js binary was downloaded, and then execute the following command to install the Node.js binary package in “/usr/local/” or "/usr/":
$ sudo tar -C /usr/local --strip-components 1 -xzf node-v0.12.7-linux-x86.tar.gz
You should now have both node and npm installed in “/usr/bin”. You can check this typing:
$ ls -l /usr/local/bin/node
$ ls -l /usr/local/bin/npm
