Using SSH keys for authentication is a secure and efficient method to access your Linux VM on Azure. By replacing traditional passwords with key-based authentication, you significantly reduce the risk of unauthorized access. Following these steps ensures that your Azure VM is set up with robust security measures right from the start.
This blog will guide you through the detailed steps to create and connect to a Linux VM on Azure, using SSH key-based authentication.
Steps in creating and connecting to a Linux VM on Azure
Setting up a Linux VM on Azure
- Login to Azure portal
- Create a Resources Group or select from an existing one
- Select the Region you want the Virtual Machine to be deployed
- Select Security type
- Select the Size of the VM according to the capacity you like to build
- Create a username
- Select the key pair name
- Click Review and then create
- Download key after the deployment pass
Step 2: Connect to the Azure VM
- Connect to virtual machine
Enter command prompt at the bottom left, then right click the command prompt to run as Administrator
- Enter yes and sudo apt-get -y update to run the update
- Then copy the the Ip address to a browser, here you are welcome to linux virtual machine.
NOTE
If yours doesn't work you can put http:// before your Ip address and it will work.
CONCLUSION
With this setup, you can confidently manage your VM on Azure, and you may consider adding extra layers of protection, like firewalls, access logging, or configuring network security groups (NSGs) to control traffic. This guide can also be reused or automated for future deployments with tools like Azure CLI or Terraform.
