Install and configure an Apache web server on Linux with DSC and Azure Automation

This post will describe how to install an apache server, check that the apache service is running and configure the default web page with Desired State Configuration and Azure Automation. After deployed, I will show how to monitor that the configuration is not drifting with DSC in Azure Automation. This DSC service with Azure Automation works both for servers in the on-prem datacenter or at a public cloud provider.

The blog post will also show how to create an easy DSC Configuration file, add it so DSC in Azure Automation, and deploy it to a Linux computer. I will not show how to create an Azure Automation account or deploy the DSC agent. If you need help to deploy DSC on Linux, please see my blog post “Easy installation and registration script for OMS and DSC on Linux” where I install OMI, DSC and the OMS agent.

Get started

To get started we have to create a DSC Configuration file. Below is anexample that will deploy an Apache web server, check that Apache is running and that the web page looks like it should. To test this configuration save the below configuration in a file named DSCLinux01.ps1. This configuration uses the Apt package installer in Linux and is tested on Debian and Ubuntu.

When the configuration file is created go to the Azure Automation account and click DSC Configurations.

Click on the “DSCLinux01” and then “Compile”. When the status is “Completed” it is time to deploy the configuration to a Linux computer.

Before the configuration can be deploy the DSC Configuration DSC needs to be installed on the Linux server that is going to use the configuration. See my blog post “Easy installation and registration script for OMS and DSC on Linux” where I install OMI, DSC and the OMS if you need help with this.

When DSC is installed and registered the server shows up under DSC Nodes. Click DSC Nodes and the server to deploy DSC configurations to.

Now it is just to wait for the configuration to be added to the server. In the picture below one can see that the configuration has been added and checked that the server is compliant with the configuration file.

To check the end result, enter the IP or DNS for the server in a web browser to check if one can see the webpage. The result should look like this.

Let’s also make a quick check on the server to see the apache is installed and the service is started.
