How to Setup Node.js on Amazon EC2
[dropcap] I [/dropcap] n my previous post
How to setup and host website with Amazon EC2 ,
We have learn about setup of Amazon EC2.Now in this post i will share that how to setup Node.js on Amazon EC2.As per previous blog after SSH Connection on Amazon EC2 we have connected to the ec2-user’s home directory.Now we can do anything with our machine and install anything. SO after connect
First Update EC2 Amazon Linux
By this we updating the computer and it will take some time to update for update use below command
sudo yum update
Type_ Yes_ when prompted and wait a few minutes for the updates to install.
after update installation
Install Node.js , NPM , Git and The GCC Compiler On Amazon EC2 Instance
So Now we are installing Node and some package which is required for Node.js and install Git to install Node.js from its Github Repo
sudo yum install gcc-c++ make
sudo yum install openssl-devel
sudo yum install git
After installation of Git we clone Node.js Repository and install stable version of **Node.js **But for Use of any Node.js Framework like Express Framework which are working with latest Node.js we need to do install latest stable version of node.js.
In these day current stable version is **v0.10.33** . you can see stable version from **Node.js** Officially site Download page [http://nodejs.org/download/](http://nodejs.org/download/) here.
git clone git://github.com/joyent/node.git
cd node
git checkout v0.10.33
./configure
make
sudo make install
Congratulation now Node.js is installed .
Now Add User’s Directory To BIN Paths TO Install more packages
sudo su
nano /etc/sudoers
By this above command nano Editor will open in this we need to find below line
Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin
and on above line we add ”:/usr/local/bin” to the end of above line so it will look like below
Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin
Now we save this file and close the editor.
Now Install NPM (Node Package Manager)
git clone https://github.com/isaacs/npm.git
cd npm
sudo make install
Now our all components install for Node.js .Now we go back to home directory and setup a site folder by which Node.js site run .Here i am making site folder to setup Node.js site.
cd ~/
mkdir site
cd site
Now we are in “site” **folder.Now we create a test file(server.js)** for** Node.js **which print
` Hello Node.js is working cheers on AWS`
This file will listen for requests coming on port 8080 and return a static response as above.
server.js - Our Node.js Server FIle
// Load the necessary servers.
var sys = require( "sys" );
var http = require( "http" );
// Create our HTTP server.
var server = http.createServer(
function( request, response ){
// Create a response.
response.writeHead( 200, {"content-type": "text/plain"} );
response.write( "Hello Node.js is working cheers on AWS... \n" );
response.end();
}
);
// Point the HTTP server to port 8080.
server.listen( 8080 );
// For logging purpose....
sys.puts( "Server is running on 8080" );
In this above Node.js Server is listening at port 8080 but due to some security reason allow requests on the standard HTTP port, 80, to be handled by our Node.js server on port 8080 we need to do some port forwarding Thanks to Steve Kemp post for this solution. Now type in your console
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to 8080
Now by above command it redirect port 80 to port 8080.
Now we have install Node.js and it enable to listen on Standard HTTP port but after logout from Amazon EC2 what will we do so to keep run **Node.js **on server we need to install a module by this it run forever on server.
install Forever using our Node Package Manager (NPM)
To keep running Node.js on Server we will install this module Forever which is develop by Nodejitsu .
sudo npm install forever
By this bunch of code set in our “site” folder related to forever. **Now we can use **Forever to launch Node.JS **on Server. But To launch **Node.js Server by forever is little bit complex command so here i am making a Bash Command File to launch the Forever command.Thanks to Bennadal for explaining this thing.
I am giving this script name is **“Start” **because by this file we are starting Node.js on Server using Forever
Start- A Bash file to start Node.js On Server using Forever
#!/bin/bash
# Invoke the Forever module (to START our Node.js server).
./node_modules/forever/bin/forever \
start \
-al forever.log \
-ao out.log \
-ae err.log \
server.js
Now we give execute permissions to this file to run it
chmod +x ./start
Same we are making a “stop” Bash file to stop it
Stop- A Bash file to stop Node.js On Server using Forever
#!/bin/bash
# Invoke the Forever module (to STOP our Node.js server).
./node_modules/forever/bin/forever stop server.js
Now we give execute permissions to this file to run it same as Start bash script
chmod +x ./stop
Now we have done all work .We make trigger to start and stop Node.js on server using Forever by Bash Script.
Ready to Fire :)
Now Execute our start Script
./start
By this it invoke Forever module and start our Node.js server (server.js) and in terminal output look like below
info: Forever processing file: server.js
Which is showing that Forever start Node.js Using server.js file which we have made earlier.
Now we see on our **public DNS as per our last article **in my case it is http://ec2-54-191-173-54.us-west-2.compute.amazonaws.com/
Now try in web browser to see that its works or not .
On web browser output is come
_**Hello Node.js is working cheers on AWS**_
Same as to Stop Node.js on Server we Type below command
./stop
Now After logout From Amazon EC2 It will work same due to Forever Module.
Hey Cheers we have install , set and host Node on Amazon EC2 Instance.
