How to install Apache WebServer on Ubuntu ?

The Apache HTTP Server is a open-source HTTP server for modern operating systems including UNIX and Windows. Apache provides a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards.

This post details, how you can install and setup the apache webserver on Ubuntu.

Install Apache Webserver

$ sudo apt-get install apache2

Once above command is installed apache2 successfully without any error, you can see that apache server is running by following command as,

yt@dev:~$ systemctl status apache2.service
● apache2.service - The Apache HTTP Server
     Loaded: loaded (/lib/systemd/system/apache2.service; enabled; preset: enabled)

             ├─56091 /usr/sbin/apache2 -k start

             └─56093 /usr/sbin/apache2 -k start

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
