A server backup is the best method for securing the data of your online projects, thereby preventing any damaging losses. Server environments are especially in need of cleverly devised backup strategies that take every type of device into account. Here, backup programs become essential. Free applications, like rsync, offer reliable and compelling alternatives to their expensive conventional...
XAMPP is the title used for a compilation of free software. The name is an acronym, with each letter representing one of the five key components. The software packet contains the web server Apache, the relational database management system MySQL (or MariaDB), and the scripting languages Perl and PHP. The initial X stands for the operating systems that it works with: Linux, Windows, and Mac OS X.
- Apache: the open source web server Apache is the most widely used server worldwide for delivery of web content. The server application is made available as a free software by the Apache Software Foundation.
- MySQL/MariaDB: in MySQL, XAMPP contains one of the most popular relational database management systems in the world. In combination with the web server Apache and the scripting language PHP, MySQL offers data storage for web services. Current XAMPP versions have replaced MySQL with MariaDB (a community-developed fork of the MySQL project, made by the original developers).
- PHP: the server-side programming language PHP enables users to create dynamic websites or applications. PHP can be installed on all platforms and supports a number of diverse database systems.
- Perl: the scripting language Perl is used in system administration, web development, and network programming. Like PHP, Perl also enables users to programme dynamic web applications.
Alongside these core components, this free-to-use Apache distribution contains some other useful tools, which vary depending on your operating system. These tools include the mail server Mercury, the database administration tool phpMyAdmin, the web analytics software solutions Webalizer, OpenSSL, and Apache Tomcat, and the FTP servers FileZilla or ProFTPd.
An XAMPP server can be installed and used with a single executable file quickly and easily, functioning as a local test system for Linux, Windows, and Mac OS X. The software packet contains the same components that are found on common web servers. Developers have the chance to test out their projects locally and to transfer them easily to productive systems. But XAMPP isn’t suitable to use as a public server, because many safety features have been deliberately left out to simplify and speed up the system for testing.
Our XAMPP tutorial will take you through the installation process for the software package on Windows. If you’re using Linux or Mac OS X, then the steps listed below for the installation process may differ.
XAMPP is a release made available by the non-profit project Apache Friends. Versions with PHP 5.5, 5.6, or 7 are available for download on the Apache Friends website.
2. Run .exe file
Once the software bundle has been downloaded, you can start the installation by double clicking on the file with the ending .exe.
3. Deactivate any antivirus software
Since an active antivirus programme can negatively affect the installation process, it’s recommended to temporarily pause any antivirus software until all XAMPP components have successfully been installed.
4. Deactivate UAC
User Account Control (UAC) can interfere with the XAMPP installation because it limits writing access to the C: drive, so we recommend you deactivate this too for the duration of the installation process. To find out how to turn off your UAC, head to the Microsoft Windows support pages.
5. Start the setup wizard
After you’ve opened the .exe file (after deactivating your antivirus programme(s) and taken note of the User Account Control, the start screen of the XAMPP setup wizard should appear automatically. Click on ‘Next’ to configure the installation settings.
6. Choose software components
Under ‘Select Components’, you have the option to exclude individual components of the XAMPP software bundle from the installation. But for a full local test server, we recommend you install using the standard setup and all available components. After making your choice, click ‘Next’.
7. Choose the installation directory
In this next step, you have the chance to choose where you’d like the XAMPP software packet to be installed. If you opt for the standard setup, then a folder with the name XAMPP will be created under C:\ for you. After you’ve chosen a location, click ‘Next’.
8. Start the installation process
Once all the aforementioned preferences have been decided, click to start the installation. The setup wizard will unpack and install the selected components and save them to the designated directory. This process can take several minutes in total. You can follow the progress of this installation by keeping an eye on the green loading bar in the middle of the screen.
9. Windows Firewall blocking
Your Firewall may interrupt the installation process to block the some components of the XAMPP. Use the corresponding check box to enable communication between the Apache server and your private network or work network. Remember that making your XAMPP server available for public networks isn’t recommended.
10. Complete installation
Once all the components are unpacked and installed, you can close the setup wizard by clicking on ‘Finish’. Click to tick the corresponding check box and open the XAMPP Control Panel once the installation process is finished.
The XAMPP Control Panel
Controls for the individual components of your test server can be reached through the XAMPP Control Panel. The clear user interface logs all actions and allows you to start or stop individual modules with a single. The XAMPP Control Panel also offers you various other buttons, including:
- Config: allows you to configure the XAMPP as well as the individual components
- Netstat: shows all running processes on the local computer
- Shell: opens a UNIX shell
- Explorer: opens the XAMPP folder in Windows Explorer
- Services: shows all services currently running in the background
- Help: offers links to user forums
- Quit: closes the XAMPP Control Panel
Individual modules can be started or stopped on the XAMPP Control Panel through the corresponding buttons under ‘Actions’. You can see which modules have been started because their names are highlighted green under the ‘Module’ title.
If a module can’t be started as a result of an error, you’ll be informed of this straight away in red font. A detailed error report can help you identify the cause of the issue.
Setting up XAMPP
A common source of error connected with Apache is blocked ports. If you’re using the standard setup, then XAMPP will assign the web server to main port 80 and the SSL port 443. The latter of these particularly is often blocked by other programmes. In the example above, it’s likely that the Tomcat port is being blocked, meaning the web server can’t be started. There are three ways to solve this issue:
- Change the conflicting port: Let’s assume for the sake of example that the instant messenger programme Skype is blocking SSL port 443 (this is a common problem). One way to deal with this issue is to change Skype’s port settings. To do this, open the programme and navigate via ‘Actions’, ‘Options’, and ‘Advanced’, until you reach the ‘Connections’ menu. You should find a box checked to allow Skype access to ports 80 and 443. Deselect this checkbox now.
- Change the XAMPP module port settings: Click the Config button for the module in question and open the files httpd.conf and httpd-ssl.conf. Replace port number 80 in httpd.conf and port number 443 in httpd-ssl.conf with any free ports, before saving the file data. Now click on the general Config button on the right-hand side and select ‘Services and Ports Settings’. Customise the ports for the module server to reflect the changes in the conf files.
- End the conflicting programme: The simplest way to avoid port conflicts in the short term is to end the conflicting programme (Skype in this case). If you restart Skype after your XAMPP module servers are already running, it will select a different port and your issue will be resolved.
You have an ‘Admin’ option located on the Control Panel for every module in your XAMPP.
- Click on the Admin button of your Apache server to go to the web address of your web server. The Control Panel will now start in your standard browser, and you’ll be led to the dashboard of your XAMPP’s local host. The dashboard features numerous links to websites for useful information as well as the open source project BitNami, which offers you many different applications for your XAMPP, like WordPress or other content management systems. Alternatively, you can reach the dashboard through localhost/dashboard/.
- You can use the Admin button of your database module to open phpMyAdmin. Here, you can manage the databases of your web projects that you’re testing on your XAMPP. Alternatively, you can reach the administration section of your MySQL database via localhost/phpmyadmin/.
Testing your XAMPP installation
To check whether your test server is installed and configured correctly, you have the option to create a PHP test page, store them on your XAMPP’s local host, and retrieve them via the web browser.
- Open the XAMPP directory through the ‘Explorer’ button in the Control Panel and choose the folder htdocs (C:\xampp\htdocs for standard installations). This directory will store file data collected for web pages that you test on your XAMPP server. The htdocs folder should already contain data to help configuration of the web server. But you should store your own projects in a new folder (like ‘Test Folder’ for example).
- You can create a new PHP page easily by using the following content in your editor and storing it as test.php in your ‘ test’ folder (C:\xampp\htdocs\test):
<html> <head> <title>PHP-Test</title> </head> <body> <?php echo '<p>Hello World</p>'; ?> </body> </html>
- The last step now is to open your web browser and load your PHP page via localhost/test/test.php. If your browser window displays the words ‘Hello World’, then you’ve successfully installed and configured your XAMPP.
