Installing Apache WebServer on Ubuntu is a straightforward process that involves updating your system, installing Apache, and configuring basic settings. By following these steps, you’ll have a reliable web server up and running, ready to host your web applications.

Now, you can check that webserver is running by visiting its home page as http://localhost OR http://YOUR_IP in browser

So, this html index page displayed comes from /var/www/html on your machine, and you can check it as,

$ tree /var/www/html/
/var/www/html/
└── index.html

0 directories, 1 file

Now, if you want to have some of your custom web page displayed from this local server, just copy that to /var/www/html and it will be accessible from the browser as localhost/custom_webpage.html
