You’ve been creating websites on your Apache installation on Windows - making a sub-directory for each site you want to design/develop. But wouldn’t it be good if you could run multiple websites on a single Apache installation - changing http://localhost/mynewsite1/, http://localhost/mynewsite2/, etc. to http://mynewsite1/, http://mynewsite2/, etc. Well you can! - with Apache Virtual Hosts. This article will show you how to run as many websites (or Virtual Hosts) as you like on your Apache installation on Windows by making a few simple additions to your Apache configuration file and your Windows hosts file.

What We’ll Assume

  • You have a working installation of Apache 2.2.4 on Windows (if not, take a look at Installing Apache, MySQL and PHP on Windows).
  • Your Apache DocumentRoot - where your local website files are - is in the default location of C:\Program Files\Apache Software Foundation\Apache2.2\htdocs (if not, simply replace all occurrences of C:/Program Files/Apache Software Foundation/Apache2.2/htdocs with whatever your DocumentRoot is - e.g. C:\www).

Let’s Get On With It

  1. Create a new folder C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\mynewsite

  2. Go to Start > Programs > Apache HTTP Server 2.2.4 > Configure Apache Server > Edit the Apache httpd.conf Configuration File

    The Apache configuration file opens (httpd.conf)

  3. Add this line at the very bottom of the file:

    NameVirtualHost localhost

    Apache will now allow multiple Virtual Hosts to run under localhost

  4. Directly under the last line you added in httpd.conf, add the following VirtualHost directive:

    <VirtualHost localhost>
        DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs/mynewsite"
        ServerName mynewsite
    </VirtualHost>
  5. Save and close httpd.conf

  6. Open C:\WINDOWS\system32\drivers\etc\hosts in Notepad

    Your Windows hosts file opens

  7. You should see this line somewhere in the file:

    127.0.0.1	localhost
  8. Directly below this line, add the following:

    127.0.0.1	mynewsite
  9. Save and close hosts
  10. Go to Start > Programs > Apache HTTP Server 2.2.4 > Control Apache Server > Restart
  11. Open mynewsite in your web browser (http://mynewsite/)
  12. If all went well, your browser will show a page with Index of /

This is it! The definitive guide to installing and configuring Apache 2.2.4, MySQL 5.0.27 and PHP 5.2.1 on Microsoft Windows XP (SP2) with support for both MySQL and MySQLi PHP extensions.

And, yes, if you follow these instructions to the letter, the software will actually work!

Before getting started with the installations, you’ll need to download the required software packages - all of which are conveniently listed in the following table.

    mysql>

Installing PHP

  1. Create a new folder C:\php
  2. Copy the contents of php-5.2.1-Win32.zip to C:\php
  3. On your desktop, right-click My Computer and select Properties
  4. In the System Properties dialogue box select the Advanced tab

    System Properties dialogue box

  5. Click the Environment Variables button
  6. In the Environment Variables dialogue box under System variables select Path

    Environment Variables dialogue box

  7. Click the Edit button
  8. In the Edit System Variable dialogue box add C:\php to the Variable value field

    Edit System Variable dialogue box

  9. Click the OK button for all open dialogue boxes

Configuring PHP

  1. In C:\php, copy the file php.ini-recommended
  2. Rename the Copy of php.ini-recommended to php.ini
  3. Open php.ini in Notepad
  4. In php.ini, find this line:

    display_errors = Off

    and enable the display of errors by changing the value to “On”:

    display_errors = On

    Note: You wouldn’t do this in a production environment - this is just for testing and development!

  5. In php.ini, find this line:

    extension_dir = "./"

    and specify the directory in which the loadable extensions (modules) reside by changing the value to “ext”:

    extension_dir = "ext"
  6. In php.ini, find these lines:

    ;extension=php_mysql.dll
    ;extension=php_mysqli.dll

    and enable both the MySQL and MySQLi extensions by uncommenting the lines:

    extension=php_mysql.dll
    extension=php_mysqli.dll
  7. In Windows Explorer, copy the following dll files:

    C:\php\libmysql.dll

    C:\php\ext\php_mysql.dll

    C:\php\ext\php_mysqli.dll

  8. Paste the dll files to C:\WINDOWS\system32

    Note: Most installations don’t require you to copy libmysql.dll to system32, but some do. So it’s better to be safe than sorry!

  9. Go to Start > Programs > Apache HTTP Server 2.2.4 > Configure Apache Server > Edit the Apache httpd.conf Configuration File

    The Apache configuration file opens (httpd.conf)

  10. Add the following three lines at the end of the file:

    LoadModule php5_module "C:/php/php5apache2_2.dll"
    AddType application/x-httpd-php .php
    PHPIniDir "C:/php"
  11. In httpd.conf, find this directive:

    <IfModule dir_module>
        DirectoryIndex index.html
    </IfModule>

    Add index.php as a directory index:

    <IfModule dir_module>
        DirectoryIndex index.php index.html
    </IfModule>
  12. Save and close httpd.conf
  13. Go to Start > Programs > Apache HTTP Server 2.2.4 > Control Apache Server > Restart

    Note: You need to restart Apache any time you make changes to the php.ini and/or httpd.conf files

Testing PHP

  1. Open Notepad and type the following: <?php phpinfo(); ?>
  2. Save the file as info.php in your web root directory (C:\Program Files\Apache Software Foundation\Apache2.2\htdocs)
  3. Close info.php
  4. Open info.php in your web browser (http://localhost/info.php)

    If PHP is installed correctly, you will see a table of information pertaining to your PHP installation environment

    phpinfo

  5. Open Notepad and type the following:

    <?php
    $mysqli = new mysqli('localhost', 'root', 'yourpassword', 'test');
    if (mysqli_connect_errno()) {
        printf('Connect failed: %s', mysqli_connect_error());
        exit();
    }
    printf('Host information: %s', $mysqli->host_info);
    $mysqli->close();
    ?>
  6. Save the file as mysqli.php in your web root directory (C:\Program Files\Apache Software Foundation\Apache2.2\htdocs)
  7. Close mysqli.php
  8. Open mysqli.php in your web browser (http://localhost/mysqli.php)

    If MySQL is enabled, you will see the following output:

    “Host information: localhost via TCP/IP”

That’s it, you’re done. Hopefully it all came together without any major dramas. If not, you have my deepest sympathies. And if that’s not enough, please leave a comment specifying exactly where it all went pear-shaped for you and I’ll do my best to get to the bottom of it.
