Install apache2.4 server on Windows systems
Step-1 Download Apache2.4Download the required version of Apache from here. Here we consider of installing Apache 2.4.43 x64 with OpenSSL support. This link will download a ".zip" file. Before installing this package make sure you have installed the Visual C++ 2015 redistributable from here
Step-2 Install Apache2.4Installation here means just extract the downloaded "zip" file to C:\Apache24 folder. Now we have to register the apache2 to windows services to start automatically when windows starts.
For this open the "Command Prompt" as Administartor and run the following Commands.
C:\Windows\System32>cd C:\Apache24\bin
C:\Apache24\bin>httpd.exe -k install
You will get 'The "Apache2.4" service is successfully installed' message means you have configured Apache2.4 service correctly on your windows machine.
Now open your browser and enter url as http://localhost, you will see a message "It Works!" means your Apache2.4 server is configured correctly and accepting requests also.
