Amazon EC2 Tutorial : Hosting Mean Stack Application

Amazon EC2 Tutorial : Hosting Mean Stack Application

   January 05, 2020       Codez Tech

---

Amazon EC2 is one of the most used and most basic services in Amazons so it makes sense to start with EC2 when you are new to AWS. But the first question is that what is EC2 in AWS ?

AMAZON EC2 HOSTING MEAN STACK APPLICATION

1. What is EC2 in AWS ?

Well to be very simple, 

1. It's basically virtual machine which includes CPU, RAM, ROM e.t.c
2. It also allows to choose different platform ( like windows, linux, ubuntu e.t.c ) while you are launching virtual machine in cloud. 
3. The Virtual machine we called it as an instance, you can easily start, stop or terminate your instance.

2. AWS EC2 Mean Stack Application Screens?

I am sharing few screens about out Mean Stack Applications that we are going to host it in AWS EC2. 

Insert - 

Mean Stack CRUD Application Insert

Update -

Delete -

3. Architecture of the Mean Stack Application

    In the below diagram, this is the architecture of our mean stack application that we are going to setting up in 2 AWS instance. In the FrontEnd Part I am using Angular 6, and

MEAN STACK APPLICATION ARCHITECTURE

whatever user interaction got happened like create, read, write and delete it's happening from Node JS. So Node Js is act as a mediator which helps to talk to my database mongo DB and get back the data to frontend. So we will be going to use 2 instance 1 for frontend and 1 for backend.

Mean Stack FrontEnd Project Link - 

git clone https://atique12@bitbucket.org/atique12/mongocrud_application_frnt_end.git

Mean Stack BackEnd Project Link -

git clone https://atique12@bitbucket.org/atique12/mongocrud_application_back_end.git

About the AMAZON EC2 Tutorial also you can see - 

2. Installation of MongoDB into AWS EC2 Instance

First if you have not registered in AWS please register first. Then launch an UBUNTU instance. Download the pem key. Open your terminal - 

ssh -i yourkey.pem ubuntu@your_ec2_public_ip

Once you have logged in then follow the below process,

For Installation of MongoDB please visit the below link - 

MongoDB-   Click here to download MongoDB

More details -

git clone https://atique1224@bitbucket.org/atique1224/aws-ec2-tutorial.git

You can also see my below videos - 

3. AWS EC2 Hosting Mean Stack Application using PM2 - 

This is the other ubuntu Instance that we are launching it. First thing we need to install Node JS, Angular 6, NVM and PM2 in the AWS EC2 instance. Then we have to clone the code inside the EC2 instance. 

Install Node JS - 

sudo apt update

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - sudo apt-get install -y nodejs 

Install NVM for changing the Node JS version -

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash source ~/.profile 

nvm ls-remote 

Install Angular 6 -

sudo npm install -g @angular/cli@6.0.7

Mean Stack FrontEnd Project Link - 

git clone https://atique12@bitbucket.org/atique12/mongocrud_application_frnt_end.git

Mean Stack BackEnd Project Link -

git clone https://atique12@bitbucket.org/atique12/mongocrud_application_back_end.git 

Then edit the file - 

Mean Stack BackEnd Project - db.js and index.js - Instead of Localhost put first instance mongo DB EC2 Public ip to db.js and 2nd instance public ip to 2nd EC2 instance.

Mean Stack FrontEnd Project - Inside src/app/shared

vi person.services.ts

Change localhost to 2nd AWS EC@ public ip.
