XAMPP-VM Frequently Asked Questions

What is the difference between XAMPP for OS X and XAMPP-VM?

  • XAMPP for OS X is a native installer for OS X. It installs Apache, PHP and other XAMPP components directly on your OS X system, in the /Applications/XAMPP folder.
  • XAMPP-VM is a virtual machine for OS X. It includes Apache, PHP and other XAMPP components and runs them in a Linux-based virtual machine on your OS X system.

Does XAMPP-VM include MySQL or MariaDB?

XAMPP-VM ships MariaDB instead of MySQL. The commands and tools are the same for both.

How do I start XAMPP-VM?

To start XAMPP-VM:

  • 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. Wait for the status icon to turn green.
  • 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-VM?

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

Can I start and stop XAMPP-VM services individually?

Yes. When you start the XAMPP-VM virtual machine, XAMPP services will also automatically start. You can navigate to the "Services" tab of the stack manager at any time to stop, start, restart or check the status of individual services.

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-VM start page, as shown below.

Is XAMPP-VM production ready?

XAMPP-VM is not meant for production use but only for development environments. The way XAMPP-VM is configured is 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-VM:

  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

It will kick off a a small security check to make the XAMPP-VM 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 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-VM, 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 install XAMPP-VM add-ons?

  • Enter the required details when prompted and wait for the installation to complete.

You should now be able to access the add-on through your browser. For example, to access WordPress, browse to http://localhost:8080/wordpress.

Where are the XAMPP-VM virtual machine files and logs?

The XAMPP-VM virtual machine files and logs are stored within your home directory on the OS X host, in the ~/.bitnami/stackman/machines/xampp/vm and ~/.bitnami/stackman/machines/xampp/log directories respectively.

Where are the main XAMPP configuration files?

The main XAMPP configuration files are located as follows:

  • Apache configuration file: /opt/lampp/etc/httpd.conf, /opt/lampp/etc/extra/httpd-xampp.conf
  • PHP configuration file: /opt/lampp/etc/php.ini
  • MySQL configuration file: /opt/lampp/etc/my.cnf

How do I send email with XAMPP?

To send email with XAMPP, use the PEAR Mail and Net_SMTP packages, which allow you to send email using an external SMTP account (such as a Gmail account). Follow these steps:

  • Install the Mail and Net_SMTP PEAR modules: pear install Net_SMTP Mail Note that if these packages are already installed in your system you see the messages below when executing that command: Ignoring installed package pear/Net_SMTP Ignoring installed package pear/Mail Nothing to install
  • Create the following example script in your "htdocs" directory to send an email: <?php require_once "Mail.php"; $from = "your-gmail-username@gmail.com"; $to = 'recipients@example.com'; $host = "ssl://smtp.gmail.com"; $port = "465"; $username = 'your-gmail-username@gmail.com'; $password = 'your-gmail-password'; $subject = "test"; $body = "test"; $headers = array ('From' => $from, 'To' => $to,'Subject' => $subject); $smtp = Mail::factory('smtp', array ('host' => $host, 'port' => $port, 'auth' => true, 'username' => $username, 'password' => $password)); $mail = $smtp->send($to, $headers, $body); if (PEAR::isError($mail)) { echo($mail->getMessage()); } else { echo("Message successfully sent!\n"); } ?>

    Remember to replace the dummy values shown with your actual Gmail address and account password. If you don't plan to use Gmail's SMTP server, replace the SMTP host details with appropriate values for your organization or ISP's SMTP server.

  • Execute the script by browsing to it using your Web browser. You should see a notification that the message was successfully sent, and the message should be delivered to the recipient email address.
How do I backup/restore my XAMPP-VM system?

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

You can create the backup as follows:

    /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-VM 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
