Does XAMPP include MySQL or MariaDB?

Since XAMPP 5.5.30 and 5.6.14, XAMPP ships MariaDB instead of MySQL. The commands and tools are the same for both.

How do I start XAMPP?

To start XAMPP:

  • Launch the stack manager by double-clicking the XAMPP icon in the mounted disk image.
  • Click the "Start" button in the "General" tab of the stack manager.
  • Once the status icon turns green, navigate to the "Services" tab and start Apache, MySQL and any other available services.
  • Navigate to the "Network" tab and enable port forwarding (port 80 of the stack to port 8080 of the host system) over SSH.
How do I stop XAMPP?

To stop XAMPP, click the "Stop" button in the "General" tab of the stack manager. Once the status icon turns red, close the stack manager window.

How can I test that everything worked?

Verify that you have enabled port forwarding (from port 80 of the stack to port 8080 of the host system) in the "Network" tab of the stack manager and type the following URL in a web browser:

http://localhost:8080

You should see the XAMPP start page, as shown below.

Is XAMPP production ready?

XAMPP is not meant for production use but only for development environments. XAMPP is configured to be open as possible to allow the developer anything he/she wants. For development environments, this is great but in a production environment, it could be fatal.

Here a list of missing security in XAMPP:

  1. The MySQL administrator (root) has no password.
  2. The MySQL daemon is accessible via network.
  3. ProFTPD uses the password "lampp" for user "daemon".
To fix most of the security weaknesses:
  • Launch the stack manager by double-clicking the XAMPP icon in the mounted disk image.
  • Ensure that all services are running in the "Services" tab of the stack manager (or start them as needed).
  • Open a new terminal from the "General" tab of the stack manager and run the following command in it:

    /opt/lampp/lampp security

This will launch a small security check to make the XAMPP installation secure.
Apache doesn't seem to start. What can I do?

This error can exist for multiple reasons. Apache displays this error under several circumstances. To find the exact reason, you have to do some research:

  • Launch the stack manager by double-clicking the XAMPP icon in the mounted disk image.
  • Open a new terminal from the "General" tab of the stack manager and run the following command in it:

    tail -2 /opt/lampp/logs/error_log

How can I make my XAMPP installation more secure?

By default, XAMPP has no passwords set and it is not recommended to run XAMPP with this configuration as it is accessible to others.To make the installation more secure:

  • Launch the stack manager by double-clicking the XAMPP icon in the mounted disk image.
  • Ensure that all services are running in the "Services" tab of the stack manager (or start them as needed).
  • Open a new terminal from the "General" tab of the stack manager and run the following command in it:

    tail -2 /opt/lampp/logs/error_log

  • You should see the following dialog on your screen. Enter responses to each prompt.

    XAMPP: Quick security check...

How do I copy files to the Apache server document root?

To copy files from the host system to the XAMPP Apache server document root, follow these steps:

  • Launch the stack manager by double-clicking the XAMPP icon in the mounted disk image.
  • Mount the /opt/lampp directory from the "Volumes" tab of the stack manager and click the "Explore" button to open the file manager.
  • Navigate to the /opt/lampp/htdocs directory in the file manager. This directory is the XAMPP Apache server document root. Copy files to it from the host system using the file manager in the usual way.
How do I access phpMyAdmin from the host system?

To access phpMyAdmin from the host system, follow these steps:

  • Launch the stack manager by double-clicking the XAMPP icon in the mounted disk image.
  • Ensure that all services are running in the "Services" tab of the stack manager (or start them as needed).
  • Navigate to the "Network" tab and ensure that port forwarding (port 80 of the stack to port 8080 of the host system) over SSH is enabled.
  • Browse to http://localhost:8080/phpmyadmin to access phpMyAdmin.

If you see an "Access denied" error, ensure that your phpMyAdmin configuration correctly reflects your MySQL credentials.

How do I enable access to phpMyAdmin from the outside?

In the basic configuration of XAMPP, phpMyAdmin is accessible only from the host system via a secure tunnel, at http://127.0.0.1:8080/phpmyadmin or http://localhost:8080/phpmyadmin.

IMPORTANT: Enabling external access for phpMyAdmin in production environments is a significant security risk. You are strongly advised to only allow access from localhost. A remote attacker could take advantage of any existing vulnerability for executing code or for modifying your data.

To enable remote access to phpMyAdmin, follow these steps:
  • Edit the /opt/lampp/etc/extra/httpd-xampp.conf file.
  • Within this file, find the lines below.

    Alias /phpmyadmin "/opt/lampp/phpmyadmin/" <Directory "/opt/lampp/phpmyadmin"> AllowOverride AuthConfig Require local

  • Then replace 'Require local' with 'Require all granted'.
  • Alias /phpmyadmin "/opt/lampp/phpmyadmin/" <Directory "/opt/lampp/phpMyAdmin"> AllowOverride AuthConfig Require all granted

  • Save the file and restart the Apache service using the stack manager.
How do I backup/restore my XAMPP system?

WARNING: The backup and restore functionality is still under development and may not work correctly.

You can create the backup as follows:

  • Launch the stack manager by double-clicking the XAMPP icon in the mounted disk image.
  • Ensure that all services are running in the "Services" tab of the stack manager (or start them as needed).
  • Open a new terminal from the "General" tab of the stack manager and run the following command in it:

    /opt/lampp/lampp backup

    or

    /opt/lampp/lampp backup secret

    Where "secret" is your MySQL root password. This command will create the following output:

    Backing up databases...
    Backing up configuration, log and htdocs files...
    Calculating checksums...
    Building final backup file...
    Backup finished.
    Take care of /Applications/XAMPP/xamppfiles/backup/xampp-backup-22-01-14.sh

    The file /Applications/XAMPP/xamppfiles/backup/xampp-backup-22-01-14.sh (in the example above) contains your backup data. Move or copy this file to a safe place.
  • Mount the /opt/lampp directory from the "Volumes" tab of the stack manager and click the "Explore" button to open the file manager.
  • Move the backup file to a safe place on the host system.

To restore the backup on a new system, you need the same version of XAMPP as on your original/source system. Follow these steps to restore the backup:

  • Launch the stack manager by double-clicking the XAMPP icon in the mounted disk image.
  • Ensure that all services are running in the "Services" tab of the stack manager (or start them as needed).
  • Mount the /opt/lampp directory from the "Volumes" tab of the stack manager and click the "Explore" button to open the file manager.
  • Copy the backup file from the host system to the mounted directory.
  • Open a new terminal from the "General" tab of the stack manager, change to the directory containing the backup file and run the following command (change the file name in the command to reflect the actual backup file name):

    ./xampp-backup-22-01-14.sh

    You should see something like this:

    Checking integrity of files... Restoring configuration, log and htdocs files... Checking versions... Installed: XAMPP 1.4.2 Backup from: XAMPP 1.4.2 Restoring MySQL databases... Restoring MySQL user databases... Backup complete. Have fun! You may need to restart XAMPP to complete the restore
