Create a Linux virtual machine with the Azure portal

Azure virtual machines can be created through the Azure portal. This method provides a browser-based user interface for creating and configuring virtual machines and all related resources. This Quickstart steps through creating a virtual machine using the Azure portal.

If you don't have an Azure subscription, create a free account before you begin.

Create SSH key pair

You need an SSH key pair to complete this quick start. If you have an existing SSH key pair, this step can be skipped. If you are using a Windows machine, follow the instructions found here.

From a Bash shell, run this command and follow the on-screen directions. The command output includes the file name of the public key file. The contents of this file are needed when creating the virtual machine.

ssh-keygen -t rsa -b 2048

Log in to Azure

Log in to the Azure portal at http://portal.azure.com.

Create virtual machine

  1. Click the New button found on the upper left-hand corner of the Azure portal.

  2. Select Compute from the New blade, select Ubuntu Server 16.04 LTS from the Compute blade, and then click the Create button.

  3. Fill out the virtual machine Basics form. For Authentication type, select SSH. When pasting in your SSH public key, take care to remove any leading or trailing white space. For Resource group, create a new one. A resource group is a logical container into which Azure resources are created and collectively managed. When complete, click OK.

    Enter basic information about your VM in the portal blade

  4. Choose a size for the VM. To see more sizes, select View all or change the Supported disk type filter.

  5. On the settings blade, select Yes under Use managed disks, keep the defaults for the rest of the settings, and click OK.

  6. On the summary page, click Ok to start the virtual machine deployment.

  7. To monitor deployment status, click the virtual machine. The VM can be found on the Azure portal dashboard, or by selecting Virtual Machines from the left-hand menu. When the VM has been created, the status changes from Deploying to Running.

Open port 80 for web traffic

By default only SSH connections are allowed into Linux virtual machines deployed in Azure. If this VM is going to be a webserver, you need to open port 80 to web traffic. This step walks you through creating a network security group (NSG) rule to allow inbound connections on port 80.

  1. On the blade for the virtual machine, in the Essentials section, click the name of the Resource group.
  2. In the blade for the resource group, click the Network security group in the list of resources. The NSG name should be the VM name with -nsg appended to the end.
  3. Click the Inbound Security Rule heading to open the list of inbound rules. You should see a rule for RDP already in the list.
  4. Click + Add to open the Add inbound security rule blade.
  5. In Name, type nginx. Make sure Port range is set to 80 and Action is set to Allow. Click OK.

Connect to virtual machine

After the deployment has completed, create an SSH connection with the virtual machine.

  1. Click the Connect button on the virtual machine blade. The connect button displays an SSH connection string that can be used to connect to the virtual machine.

  2. Run the following command to create an SSH session. Replace the connection string with the one you copied from the Azure portal.

ssh <replace with IP address>

Install NGINX

Use the following bash script to update package sources and install the latest NGINX package.

#!/bin/bash

# update package source
apt-get -y update

# install NGINX
apt-get -y install nginx

View the NGIX welcome page

With NGINX installed and port 80 now open on your VM from the Internet - you can use a web browser of your choice to view the default NGINX welcome page. Be sure to use the publicIpAddress you documented to visit the default page.

Delete virtual machine

When no longer needed, delete the resource group, virtual machine, and all related resources. To do so, select the resource group from the virtual machine blade and click Delete.
