Complete removal of apache2 under linux

Question

I have problem with removing apache2 under ubuntu. What I tried is:

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

unfortunatelly after any of upper commands, there are still files:

sudo find / -name "apache2"
/var/log/apache2
/var/lib/update-rc.d/apache2
/var/cache/apache2
/usr/share/doc/apache2.2-common/examples/apache2
/usr/share/apache2
/usr/lib/apache2
/usr/lib/apache2/mpm-event/apache2
/usr/lib/apache2/mpm-itk/apache2
/usr/lib/apache2/mpm-worker/apache2
/usr/lib/apache2/mpm-prefork/apache2
/usr/sbin/apache2
/run/apache2
/run/lock/apache2
/etc/init.d/apache2
/etc/apache2
/etc/cron.daily/apache2
/etc/default/apache2
/etc/logrotate.d/apache2

When i run sudo /etc/init.d/apache2 start

 * Starting web server apache2                                                                                                                                                                            apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
Action 'start' failed.
The Apache error log may have more information.

After typing localhost in browser it responds with:

Forbidden

You don't have permission to access / on this server.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

Could this files disturb new apache server installation? I've checked them all but nothing interresting found.

EDIT: Upper output is after removal of the server. After removal of all files from sudo find / -name "apache2" I did install again sudo apt-get install apache2 . sudo /etc/init.d/apache2 outputs with:

 * Starting web server apache2                                                                                                                                                                            Segmentation fault
Action 'start' failed.
The Apache error log may have more information.

But error.log and access.log are empty.

Apache install:

sudo apt-get install apache2

After this operation, 1,240 kB of additional disk space will be used.
Do you want to continue [Y/n]? 

Is it normal that it asks only for 1,240 kB space ?

Answer 1

First stop apache:

sudo service apache2 stop

Then, 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 as below:

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