From ArchWiki

XAMPP is an easy to install Apache distribution containing MariaDB, PHP, Perl and ProFTPD. It contains: Apache, MariaDB, PHP & PEAR, Perl, ProFTPD, phpMyAdmin, OpenSSL, GD, Freetype2, libjpeg, libpng, gdbm, zlib, expat, Sablotron, libxml, Ming, Webalizer, pdf class, ncurses, mod_perl, FreeTDS, gettext, mcrypt, mhash, eAccelerator, SQLite and IMAP C-Client.

## Installation

Install the xamppAUR package.

## Configuration

The default configuration should work out of the box. Setting the individual parts of XAMPP can by made by editing following files:

- `/opt/lampp/etc/httpd.conf` — Apache configuration. For example you can change folder with web page's source files.
- `/opt/lampp/etc/php.ini` — PHP configuration.
- `/opt/lampp/phpmyadmin/config.inc.php` — phpMyAdmin configuration.
- `/opt/lampp/etc/proftpd.conf` — ProFTPD configuration.
- `/opt/lampp/etc/my.cnf` — MySQL configuration.

If you would like to set up security of server, just run

    # /opt/lampp/xampp security

You will be asked step by step to choose passwords for web page's access, user "pma" for phpMyAdmin, user "root" for MySQL and user "daemon" for ProFTPD.

## Usage

Use the following commands to control XAMPP:

    # /opt/lampp/xampp start,stop,restart

Alternatively, you can start, stop, or restart `xampp.service`.

### Autostart on boot

In order to start XAMPP at boot, enable `xampp.service`.

## Tips and tricks

### Hosting files outside the htdocs directory

The document root (web root) directory is located at `/opt/lampp/htdocs/`. All files placed in this directory will be processed by the web server.

To host other files on your system with XAMPP, you can configure an alias with Apache.

- Edit Apache's `/opt/lampp/etc/httpd.conf` with your favorite editor.
- Find `DocumentRoot`, you will see something like:

    DocumentRoot "/opt/lampp/htdocs"
    <Directory "/opt/lampp/htdocs">
        ...
        ...

    </Directory>

- In the next line after `</Directory>` paste this:

    <Directory "/yourDirectory/">
        Options Indexes FollowSymLinks ExecCGI Includes
        AllowOverride All
        Require all granted
    </Directory>

- Next find the `<IfModule alias_module>`:

    <IfModule alias_module>

        #
        # Redirect: Allows you to tell clients about documents that used to
        # exist in your server's namespace, but do not anymore. The client
        # will make a new request for the document at its new location.
        # Example:
        # Redirect permanent /foo http://www.example.com/bar
      ...
    </IfModule>

- And before the `</IfModule>` paste this:

    Alias /yourAlias /yourDirectory/

- Next find the `<IfModule unixd_module>`:

    <IfModule unixd_module>

      ...
      ...
        User daemon
        Group daemon
    </IfModule>

- And change the `daemon` with `yourUser` and `yourGroup`:

    User yourUser
    Group yourGroup

- Now do not forget to restart Apache:

    # /opt/lampp/xampp restart

This will allow you to host files from your home directory (or any other directory) with XAMPP.

In the above example, you can access the files by pointing your web browser to `localhost/yourAlias`.

### Debugging and profiling with Xdebug and XAMPP

See https://xdebug.org/find-binary.php for detailed instructions.

You must first download the XAMPP Development Tools from the same download page, https://www.apachefriends.org/en/xampp-linux.html[dead link 2022-09-23 ⓘ].

Extract this into your XAMPP directory:

    # tar xvfz xampp-linux-devel-x.x.x.tar.gz -C /opt

You should be able to successfully run `/opt/lampp/bin/phpize` in your xdebug folder.

### Local test server security

Apache, MySQL and ProFTPD can be configured so that they only listen to requests from your own computer. For most test systems this is fine and it greatly reduces the risk because the services are not reachable from the Internet.

Before you start XAMPP for the first time find and edit these files:

For Apache edit the files `/opt/lampp/etc/httpd.conf` and `/opt/lampp/etc/extra/httpd-ssl.conf`. Look for lines starting with "Listen" such as

    Listen 80

and replace them with

    Listen 127.0.0.1:80

For MySQL open the file `/opt/lampp/etc/my.cnf` find the section "[mysqld]" and add this line

    bind-address=localhost

For ProFTPD, add the following lines to `/opt/lampp/etc/proftpd.conf` under the "DefaultServer" section

    DefaultAddress 127.0.0.1
    SocketBindTight on

After starting the services, verify the result by going to a command window and start and execute:

    $ ss -tln

The local address column should always start with 127.0.0.1 or ::1, never with 0.0.0.0.

### Manual installation

To install XAMPP manually instead of following #Installation, download the installer from the website, make it executable and run it by typing:

    # ./xampp-linux-x64-version-installer.run

Note: The libxcrypt-compat, net-tools and inetutils packages are required dependencies, so make sure they are installed before launching XAMPP.
Tip: By default the installer uses the Qt backend for its UI. If you want it to use the GTK backend instead, launch:

    # ./xampp-linux-x64-version-installer.run --mode gtk

If you do not want to use any graphical interface and prefer to install XAMPP directly from the terminal, launch:

    # ./xampp-linux-x64-version-installer.run --mode text

For further options, launch as normal user:

    $ ./xampp-linux-x64-version-installer.run --help

You can now create a systemd service for XAMPP:

    /etc/systemd/system/xampp.service

    [Unit]
    Description=XAMPP

    [Service]
    ExecStart=/opt/lampp/xampp start
    ExecStop=/opt/lampp/xampp stop
    Type=forking

    [Install]
    WantedBy=multi-user.target

#### Manual removal

If you have installed XAMPP manually you will need to remove it manually as well. Be sure to stop all XAMPP services.

    # /opt/lampp/xampp stop

All the files needed by XAMPP to be installed are located in the previous `/opt/lampp` folder. So, to uninstall XAMPP:

    # rm /etc/systemd/system/xampp.service
    # rm -r /opt/lampp

Note:

- Be sure to backup your files before doing this (such as files in `/opt/lampp/htdocs`).
- If you created symlinks, you may need to destroy them too.
- Do not use this method if you have installed the package; uninstall the package instead.

## Troubleshooting

### PhpMyAdmin 403 Access Forbidden

If your http://localhost/phpmyadmin returns "403 Access Forbidden", you need to edit the following settings in `/opt/lampp/etc/extra/httpd-xampp.conf`:

    <Directory "/opt/lampp/phpmyadmin">
    	AllowOverride AuthConfig Limit
    	#Order allow,deny
    	#Allow from all
    	Require all granted
    </Directory>
