Video: Changing software versions with WampServer add-ons

WampServer makes it very easy to switch between different versions of each of its software components. Let's say for example that you are working with the legacy PHP and MySQL application and the production environment for this application uses an older version of MySQL, MySQL 5.1. When you installed WampServer, you got the most recent version of MySQL, 5.5, but you can install the two versions side-by-side and you can do this with all three components: Apache, PHP and MySQL.

Viewers: in countries Watching now:

Installing Apache, MySQL, and PHP with David Gassner describes how to install and configure Apache HTTP server, MySQL database server, and PHP, known as the AMP stack, on a local development computer. Chapters are devoted to multiple installation approaches: installing the components separately on both Windows and Mac (including coverage of Apache and PHP on Mac OS X 10.7 Lion and 10.8 Mountain Lion), installing the pre-packaged Apache and MySQL distributions in WampServer on Windows and MAMP on Mac, and installing the cross-platform XAMPP and Bitnami on both Mac and Windows. Exercise files are included with the course.

This course was updated on 07/06/2012.

Topics include:
  • Performing Apache, PHP, and MySQL as separate installs
  • Activating Apache and PHP on Leopard, Snow Leopard, and Lion
  • Setting the MySQL root user password
  • Installing WampServer
  • Changing software versions with WampServer add-ons
  • Installing MAMP
  • Configuring MAMP's Apache and MySQL server ports
  • Installing XAMPP for Windows and Mac
  • Managing MySQL security through XAMPP
  • Installing Bitnami for Windows and Mac
  • Detecting and handling port conflicts
  • Working with Apache and IPV6 in Windows 8

Changing software versions with WampServer add-ons

WampServer makes it very easy to switch between different versions of each of its software components. Let's say for example that you are working with the legacy PHP and MySQL application and the production environment for this application uses an older version of MySQL, MySQL 5.1. When you installed WampServer, you got the most recent version of MySQL, 5.5, but you can install the two versions side-by-side and you can do this with all three components: Apache, PHP and MySQL.

These are called add-ons. To get to the add-ons, go to the WampServer Downloads Screen and scroll down a bit and you'll see links for PHP, Apache and MySQL add-ons. There's also a link for Beta add-ons, but these are actually full installers of WampServer. There is one there, for example, that let's you install the most recent version of PHP 5.4 as a Beta. I'm going to demonstrate multiple versions of MySQL. But again you can do this with Apache and PHP as well.

I'll click the link, Download MySQL Addons, and I'll see that there are versions of MySQL going all the way back to 4.1.2. I'll choose the most recent 5.1 distribution, 5.1.41. I'll click the link and download the software to my Desktop. Now I've already downloaded it and here it is. To run the add-on installer, just double-click it and run through all of the dialogs, including any User Account Control dialogs that might appear.

The add-on installers don't have any options. So just follow through the dialogs and complete the installation. You don't have to stop WampServer before you do the installation. If any restarts are required, the installer will handle it for you. Let's see what happened. I'll go to the system tray and click the WampServer icon and then I'll go to MySQL > Version. I'll see that I have both the newest version, the one that was originally installed and the older version.

I'll go to the Localhost link and show that I'm running MySQL version 5.5.2. I'll close the browser and go back to the system tray icon to the Admin menu to MySQL > Version and I'll choose 5.1.41. You'll see the color of the icon change momentarily as the WampServer installation restarts. Then, I'll go to the icon and I'll choose Localhost again and I'll see MySQL version has changed to 5.1.

So now I can easily switch back and forth between the versions and work with the version of MySQL that I need for my current application. You can do this with Apache and PHP as well. Switching between the different versions of the individual components as needed, you might find certain incompatibilities. For example one version of PHP might not work with another version of Apache, but you can always return to your original versions to get a working AMP Stack.

Q: I followed the procedure in the "Installing XAMP for Windows" video, but 1) I got no text file popup after install, and 2) the Admin button does not bring up phpMyAdmin page. Nothing happens even though the Running button is green.

A: The text window not popping up after the installation is just a difference in the installation flow; it shouldn't cause any functional problems.

The issue around phpMyAdmin not opening correctly from the Xampp Control Panel has come up before. There is a bug in the newest version of Xampp for Windows (version 1.7.4) that affects the Control Panel. After starting the Control Panel, and then starting both Apache and MySQL, clicking the MySQL Admin button doesn't open the browser to the phpMyAdmin as expected. However, both MySQL and phpMyAdmin are working correctly.

Follow these steps instead:
  1. Click the Admin button next to Apache to open the Xampp home page in the browser.
  2. Click phpMyAdmin under the Tools section of the menu on the left side of the page.
phpMyAdmin should open correctly. From that point, you should be able to manage your database.
Q: I'm using TextWrangler on the Mac to uncomment the following line in the httpd.conf file, as shown in the video "Activating PHP with the included Apache server" in Chapter 2:

LoadModule php5_module libexec/apache2/libphp5.so

When I try to save the changes, I get the message "Error code: -5000". What's going wrong?
A: This is a common issue with the latest version of TextWrangler. Here's another way of editing the file with a command line editor named Pico that's included in Mac OS X. Remember, most text editors don't give you the ability to edit files as the "root user", and you need those rights to edit the httpd.conf file.

Unlike TextWrangler, Pico doesn't accept mouse input, so you have to do everything with the keyboard:
  1. Open Terminal from /Applications/Utilities/Terminal.
  2. Type sudo pico /private/etc/apache2/httpd.conf.
  3. Type your password and press Return.
  4. Press Ctrl+W for 'Where is'.
  5. Type 'php' and press Return. You should find the commented-out line with php5_module
  6. Delete the '#' at the beginning of the line.
  7. Press Ctrl+X for 'Exit'.
  8. Press Y for 'Yes'.
  9. Press Return to save and exit
We recommend also using Pico to edit the php.ini file.
Q: After downloading XAMPP I was unable to start Apache from the control panel. MySQL started fine. When I click the Start button next to Apache it looks like it starts and then stops. Here is the output:

Busy
Apache Started (Port 80)

The MySQL button says "running" with a stop button; the Apache button still? says start no matter how many time I click it.
A: This usually means that another program is using Port 80 (the port that Apache needs). Port 80 is used for any web server, so you either have another web server running or you're running something else (usually Skype) that is using Port 80.

If you're running Skype (and this is really common), you need to configure it to use a different port. If it's not Skype, it may be that you're running another web server or IIS (Microsoft Internet Information Server, the web server that comes with Windows), which you'll need to quit.
Q: This course was updated on 07/06/2012. What changed?
A: A few of the WampServer movies were updated to reflect the new user interface. We also added movies on installing Bitnami, an open source stack solution, and troubleshooting Apache to work with IPV6 on Windows 8.
Q: This course was updated on 01/09/2012. What changed?
A: Two new movies were added to Chapter 2, "Installing Separate Components on Mac OS X," to reflect the changes in the latest version of Mac OS X, Mountain Lion (version 10.8). These movies cover activating Apache and configuring personal site folders in Mountain Lion.
Q: This course was updated on 8/23/2013. What changed?
A: We added new software download locations and coverage of Apache HTTP Server 2.4 on Windows, as well as information on managing Apache from the command prompt, editing hidden config files with the nano editor, and installing the new version of Bitnami on Windows and Mac OS X.
