About

This repo breaks down the process of Building and running a web application with the a MEAN based web application on a new Azure Linux virtual machine.

MEAN is a development stack for building and hosting web applications. MEAN is an acronym for its component parts: MongoDB, Express, AngularJS, and Nodejs.

Getting Started

  First, We have to create a virtual machine to host our MEAN web application, to do so, we will use Azure CLI, Install Azure CLI if you don't have it installed on your system. Or, login to your azure account and use Azure Cloud Shell.

- Create a VM to host your web application

  Azure groups resources (a container that holds the resources) in whats called resource group, before you create other resources on Azure.
So, in order to create a VM you've to create a resource group.

To simplify the process, I will declare that value to reuse later on.

$ $RESOURCE_GROUP_NAME = <CHOOSE_YOUR_RESOURCE_GROUP_NAME>
# example: $RESOURCE_GROUP_NAME = "MEAN-STACK-RG"
$ $VM_NAME = <CHOOSE_YOUR_VM_NAME>
$ $ADMIN_USERNAME = <CHOOSE_ADMIN_NAME>

1. Creating the resource group :

$ az group create --name $RESOURCE_GROUP_NAME --location "eastus"

2. Next, We will create Ubuntu Linux Virtual Machine :

$ az vm create \
 --resource-group $RESOURCE_GROUP_NAME \
 --name $VM_NAME \
 --image Canonical:0001-com-ubuntu-server-focal:20_04-lts:latest \
 --admin-username $ADMIN_USERNAME \
 --generate-ssh-keys

Wait for it to finish, After its done you should see an Object, Copy & save the publicIpAddress

{
  "fqdns": "",
  "id": "/subscriptions/. . . ./$VM_NAME",
  ...
  "publicIpAddress": "",
}

$ $VM_IP_ADDRESS = <publicIpAddress>

3. Next, We allow the incoming HTTP traffic to the web application you'll later create, by opening the port 80:

$ az vm open-port \
  --port 80 \
  --resource-group $RESOURCE_GROUP_NAME \
  --name $VM_NAME \

4. Create an SSH connection to your VM.

$ ssh $ADMIN_USERNAME@$VM_IP_ADDRESS

When prompted, enter yes to trust future connections.

With your Ubuntu VM ready to go, you're ready for the next step.

- Install each component of the MEAN stack

  Now that you ssh to the VM, You'll start by installing MongoDB.

• First, we'll make sure all current packages are up to date.

$ sudo apt update && sudo apt upgrade

• I. Install MongoDB :

$ sudo apt-get install mongodb

When installation is complete, the service automatically start up. You can confirm by running this command:

$ sudo systemctl status mongodb

    ● mongodb.service - An object/document-oriented database
        Loaded: loaded (/lib/systemd/system/mongodb.service; enabled; vendor preset: enabled)
        Active: active (running) since Fri 2022-02-25 21:05:06 UTC; 10min ago
          Docs: man:mongod(1)
      Main PID: 641 (mongod)
          Tasks: 23 (limit: 4102)
        Memory: 209.4M
        CGroup: /system.slice/mongodb.service
                └─641 /usr/bin/mongod --unixSocketPrefix=/run/mongodb --config /etc/mongodb.conf

• II. Next, Install Nodejs :

Register the Nodejs repository so the package manager can locate the packages,

$ curl -sL https://deb.nodesource.com/setup_16.x | sudo -E bash -

Install the Nodejs:

$ sudo apt install nodejs

When installation is complete, Run node -v to verify the installation:

$ node -v
v16.14.0
