Apache, in general, is most widespread web server. I believe that more than 90% of websites are hosted on Apache and increase usage of open source technologies, makes it more present in corporate environment. Installation is very easy, but additional configuration can be trickier. You will need no more then 2 minutes to install Apache2.
Login to your Ubuntu server and type following:
ittut@ubuntu:~$ sudo apt-get install apache2
You cann add switch -y to confirm installation automatically, but there is a chance to miss out information about additional packages that will be installed along with Apache2 (Slide 1).
So, confirm with Y in order to proceed with installation. That is about everything.
Now little bit about configuration.
You will use plain text to configure Apache2. Configuration resides on apache2.conf file located in /etc/apache2/ directory. So do following in order to access configuration file:
ittut@ubuntu:~$ sudo nano /etc/apache2/apache2.conf
Now follow the comments to configure or change features.
This tutorial is short, but note the following tutorials in which I will explain configuration files.
