How do I cleanly remove apache2 server on ubuntu server and then reinstall?

I am having some wierd issues with Apache2 server on my ubuntu server. I believe some configuration files may have been tampered with. What is the easiest way to remove apache2 completely from my server. I am aware of how to install by using

sudo apt-get install apache2

but, I just want to make sure I completely remove apache2.

Solution 1:

Run the following two commands:

sudo apt-get --purge remove apache2
sudo apt-get remove apache2-common

Solution 2:

First stop your server obviously:

sudo service apache2 stop

Remove apache2 packages and dependencies:

sudo apt-get purge apache2 apache2-utils apache2.2-bin apache2-common
sudo apt-get autoremove --purge

If you manually modified or installed stuff, apt might not remove it. Check what's left:

whereis apache2

Have a look whats inside these directories, and if you're confident you want to trash it, manually remove the directories. In my case:

sudo rm -Rf /etc/apache2 /usr/lib/apache2 /usr/include/apache2

Solution 3:

I think you can try this out.

APACHE_PKGS=`sudo dpkg --get-selections | grep apache | cut -f 1`

In your Terminal then check to see if it's there:

echo $APACHE_PKGS

Should show something like:

apache2 apache2-mpm-prefork apache2-utils apache2.2-common and many more. Then you run this command:

sudo apt-get remove --purge $APACHE_PKGS
sudo apt-get install $APACHE_PKGS

And you should be good to go.
