Install Node.js on Amazon Linux (EC2)

Installing Node.js on Amazon Linux AMI

The following will guide you through the process of installing Node.js on an AWS EC2 instance running Amazon Linux AMI 2016.09 - Release Notes

For this process I'll be using a t2.micro EC2 instance running Amazon Linux AMI (ami-d41d58a7). Once the EC2 instance is up-and-running, connect to your server via ssh

  • Make sure our server has the latest packages : sudo yum update -y
  • Install required packages : sudo yum install -y gcc gcc-c++ make openssl-devel

Installing Node.js

For the next steps, use /tmp as the working directory

  • Download the Node.js source code, select the recommended LTS version via the Node.js download page and copy the URL of the "Source Code" -package : curl -O

At this time of writing the current version is v4.6.0 (which includes npm 2.15.9)

  • Unpack and cleanup : tar -xvf node-v4.6.0.tar.gz && rm node-v4.6.0.tar.gz
  • Configure, make and install,... this may take a while, especially the compiling part.
$ cd node-v4.6.0
$ ./configure
$ make
$ sudo make install

You can verify afterwards if the installation was successful by checking the versions of node and npm :

  • node -v, returns value v4.6.0
  • npm -v, returns value 2.15.9

If by any chance, your are in the root environment and the previous command returns "-bash: node: command not found", you can fix this by creating the following symbolic links :

sudo ln -s /usr/local/bin/node /usr/bin/node
sudo ln -s /usr/local/lib/node /usr/lib/node
sudo ln -s /usr/local/bin/npm /usr/bin/npm	

Testing Node.js

The best method to test Node.js is actually run an application. This this prurpose we'll configure and runs a simple webserver. Again, let's use /tmp as our working directory..

  • Create a subdirectory : mkdir www
  • Enter the directory : cd www
  • Create a file called server.js and edit the contents of the file : nano server.js
  • Paste the following code and save :
var http = require('http');

var server = http.createServer(function (request, response) {  
  response.writeHead(200, {"Content-Type": "text/html"});
  response.end("<h3>Node webserver running</h3>\n");

console.log("Node.js is listening on port 8080");  
  • Start the application : node server.js
  • Open a browser and go to the public IP address of the EC2 instance to test : http://<ip-address-ec2-instance>:8080
  • As a result you should see the "Node webserver running" -message

Make sure the security group applied to your EC2 instance allows inbound traffic to port 8080 !

In an adjacent gist, I'm adding an instance of the Ghost blogging platform - link (coming soon)

Amazing! Thanks.
