sudo chown -hR nobody /opt/lampp

After executing the above command, make your htdocs accessible using the command listed in above post(point no. 2)

This may result in a phpMyAdmin error. To tackle this problem, change the ownership of /opt/lampp/phpmyadmin and permissions accordingly:

sudo chown -hR username /opt/lampp/phpmyadmin
sudo chmod 755 /opt/lampp/phpmyadmin

This will remove any phpmyadmin error.

1) After downloading your XAMPP package, do not use any GUI utility to extract it. please use the tar command with root permission (So that you can access you /opt directory)

sudo tar -xzvf xampp-package-name -C /opt/

Using the archival tools other than tar will result in problems.

2) When you execute the above command, the directory is inaccessible to you as a normal user. To access this directory you will need root privileges with sudo command. This is a problem while developing. As a workaround, we will make htdocs accessible by your current user using the following commands.

sudo chown -hR username /opt/lampp/htdocs
sudo chmod -R 755 /opt/lampp/htdocs

The above method wont show any warning as the lampp directory is not accessible to the world (except for htdocs). The above method works because mysql requires access to the /opt/lampp directory as “nobody”. When you perform chown for your user, nobody comes under others and 755 wont work and the only solution is 777 (which is bad).
