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 and installing a webserver on the VM.
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.
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. Copy the contents of the public key file to the clipboard.
ssh-keygen -t rsa -b 2048
Log in to Azure
Log in to the Azure portal at http://portal.azure.com.
Create virtual machine
Click the New button found on the upper left-hand corner of the Azure portal.
Select Compute, and then select Ubuntu Server 16.04 LTS.
Enter the virtual machine information. For Authentication type, select SSH public key. When pasting in your SSH public key, take care to remove any leading or trailing white space. When complete, click OK.
Select a size for the VM. To see more sizes, select View all or change the Supported disk type filter.
Under Settings, keep the defaults and click OK.
On the summary page, click Ok to start the virtual machine deployment.
The VM will be pinned to the Azure portal dashboard. Once the deployment has completed, the VM summary automatically opens.
Connect to virtual machine
Create an SSH connection with the virtual machine.
Click the Connect button on the virtual machine properties. The connect button displays an SSH connection string that can be used to connect to the virtual machine.
Run the following command to create an SSH session. Replace the connection string with the one you copied from the Azure portal.
Use the following bash script to update package sources and install the latest NGINX package.
#!/bin/bash # update package source sudo apt-get -y update # install NGINX sudo apt-get -y install nginx
When done, exit the SSH session and return the VM properties in the Azure portal.
Open port 80 for web traffic
A Network security group (NSG) secures inbound and outbound traffic. When a VM is created from the Azure portal, an inbound rule is created on port 22 for SSH connections. Because this VM hosts a webserver, an NSG rule needs to be created for port 80.
- On the virtual machine, click the name of the Resource group.
- Select the network security group. The NSG can be identified using the Type column.
- On the left-hand menu, under settings, click Inbound security rules.
- Click on Add.
- In Name, type http. Make sure Port range is set to 80 and Action is set to Allow.
- Click OK.
View the NGINX welcome page
With NGINX installed, and port 80 open to your VM, the webserver can now be accessed from the internet. Open a web browser, and enter the public IP address of the VM. The public IP address can be found on the VM properties in the Azure portal.
Clean up resources
When no longer needed, delete the resource group, virtual machine, and all related resources. To do so, select the resource group for the virtual machine and click Delete.
In this quick start, you’ve deployed a simple virtual machine, a network security group rule, and installed a web server. To learn more about Azure virtual machines, continue to the tutorial for Linux VMs.
