Ubuntu Server 14.04 - Install Nodejs

In this tutorial, you will be introduced how to install Nodejs by using Distro-Stable Version or a PPA (personal package archive).

How To Install the Distro-Stable Version
First, you should refresh your local package index prior and then install from the repositories:

1 2	sudo apt-get update sudo apt-get install nodejs

Then, you should install npm (Node Package Manager) because by default Ubuntu Server 14.04 does not include npm package in nodejs package

1	sudo apt-get install npm

How To Install Using a PPA from NodeSource
The versions of Node.js on NodeSource are more up-to-date than the official Ubuntu repositories.

First, install the PPA in order to get access to its contents:

1	curl -sL https://deb.nodesource.com/setup | sudo bash -

Then, install Node.js package:

1	sudo apt-get install nodejs

Note that when you install from NodeSource, the Node.js package also contains npm package, so you do not need to install npm. But to make sure all npm packages can run right, you should need to install build-essential packge:

1	sudo apt-get install build-essential

To verify Node.js installed successfully, you type nodejs and see the command line >

Ubuntu Server 14.04 - Config static IP address

Ubuntu 14.04 no longer allows you to edit "/etc/resolv.conf directly". Instead, you have to modify "/etc/resolvconf/resolv.conf.d/" head or tail. But it will be easiest to set this along side your ethernet config, in my opinion.

You need to edit the file "/etc/network/interfaces":

1	sudo vi /etc/network/interfaces

Then change to include the following:

1 2 3 4 5 6 7 8 9 10 11 12 13

# The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 #iface lo inet interface iface eth0 inet static address 192.168.1.200 netmask 255.255.255.0 gateway 192.168.1.1 network 192.168.1.0 broadcast 192.168.1.255 dns-nameservers 8.8.8.8 8.8.4.4

Finally, restart your ethernet

1	ifdown eth0 && ifup eth0
