After to start XAMPP simply call this command:
sudo /opt/lampp/lampp start
You should now see something like this on your screen:
Starting XAMPP 1.8.1...
LAMPP: Starting Apache...
LAMPP: Starting MySQL...
LAMPP started.
If you have this
Starting XAMPP for Linux 1.8.1...
XAMPP: Another web server daemon is already running.
XAMPP: Another MySQL daemon is already running.
XAMPP: Starting ProFTPD...
XAMPP for Linux started
. The solution is
sudo /etc/init.d/apache2 stop
sudo /etc/init.d/mysql stop
And the restast with sudo //opt/lampp/lampp restart

/opt/lampp/lampp security
After the change this file
sudo kate //opt/lampp/etc/extra/httpd-xampp.conf
Find and replace on
