Using Apache with Microsoft Windows

This document explains how to install, configure and run Apache 1.3 under Microsoft Windows. Please note that at this time, Windows support is entirely experimental, and is recommended only for experienced users. The Apache Group does not guarantee that this software will work as documented, or even at all. If you find any bugs, please document them on our bug reporting page. Contributions are welcomed, please submit your code or suggestions to the bug report page, or join the new-httpd mailing list.

The bug reporting page and new-httpd mailing list are not provided to answer questions about configuration or running Apache. Before you submit a bug report or request, first consult this document, the Frequently Asked Questions page and the other relevant documentation topics. If you still have a question or problem, post it to the comp.infosystems.www.servers.ms−windows newsgroup, where many Apache users and several contributions are more than willing to answer new and obscure questions about using Apache on Windows.

deja.com’s newsgroup archives offer easy browsing of previous questions. Searching the newsgroup archives, you will usually find your question was already asked and answered by other users!

Warning: Apache on NT has not yet been optimized for performance. Apache still performs best, and is most reliable on Unix platforms. Over time NT performance has improved, and great progress is being made in the upcoming version 2.0 of Apache for the Windows platforms. Folks doing comparative reviews of webserver performance are still asked to compare against Apache on a Unix platform such as Solaris, FreeBSD, or Linux.

Most of this document assumes that you are installing Windows from a binary distribution. If you want to compile Apache yourself (possibly to help with development, or to track down bugs), see Compiling Apache for Microsoft Windows.

Requirements

Apache 1.3 is designed to run on Windows NT 4.0 and Windows 2000. The binary installer will only work with the x86 family of processors, such as Intel’s. Apache may also run on Windows 95 and 98, but these have not been tested. In all cases TCP/IP networking must be installed.

If running on NT 4.0, installing Service Pack 3 or 6 is recommended, as Service Pack 4 created known issues with TCPIP/WinSock integrity that were resolved in later Service Packs.

Note: “Winsock 2” is required for Apache 1.3.7 and later.

If running on Windows 95, the “Winsock2” upgrade must be installed before Apache will run. “Winsock2” for Windows 95 is available here or via here. Be warned that the Dialup Networking 1.2 (MS DUN) updates include a Winsock2 that is entirely insufficient, and the Winsock2 update must be reinstalled after installing Windows 95 dialup networking.

Downloading Apache for Windows

Information on the latest version of Apache can be found on the Apache web server at http://www.apache.org/httpd. This will list the current release, any more recent alpha or beta-test releases, together with details of mirror web and anonymous FTP sites.

You should download the binary build of Apache for Windows named as apache_1_3_#-win32-with_src.msi if you are interested in the source code, or simply apache_1_3_#-win32-no_src.msi if you don’t plan to do anything with the source code and appreciate a faster download. Each of these files contains the complete Apache runtime. You must have the Microsoft Installer version 1.10 installed on your PC before you can install the Apache runtime distributions. Windows 2000 and Windows ME are both delivered with the Microsoft Installer support, others will need to download it. Instructions on locating the Microsoft Installer, as well as the binary distributions of Apache, are found at http://httpd.apache.org/dist/binaries/win32/

The source code is available in the -with_src.msi distribution, or from the http://httpd.apache.org/dist/ distribution directory as a .zip file. If you plan on compiling Apache yourself, there is no need to install either .msi package. The .zip file contains only source code, with MS-DOS line endings (that is cr/lf line endings, instead of the single lf used for Unix files.)

While the source is also available as a .tar.gz .tar.Z archive, these contain unix lf line endings that cause grief for Windows users. To use those archives, you must convert at least the .mak and .dsp files to have DOS line endings before MSVC can understand them. Please stick with the .zip file to spare yourself the headache.

Note: prior to 1.3.17 Apache was distributed as an InstallShield 2.0 .exe file. With an increasing number of users unable to run the InstallShield package [on Windows ME or Windows 2000] the binaries were repackaged into the readily available Microsoft Installer .msi format.

Installing Apache for Windows

Run the Apache .msi file you downloaded above. This will prompt you for:

  • your name and company name, and on Windows NT/2000, whether or not you want all users to access Apache as a Service, or if you want it installed to run when you choose the Start Apache shortcut.
  • your Server name, Domain name and administrative email account.
  • the directory to install Apache into (the default is C:\Program Files\Apache Group\Apache although you can change this to any other directory you wish)
  • the installation type. The “Complete” option installs everything, including the source code if you downloaded the -with_src.msi package. Choose the “Custom” install if you choose not to install the documentation, or the source code from that package.

During the installation, Apache will configure the files in the conf directory for your chosen installation directory. However if any of the files in this directory already exist they will not be overwritten. Instead the new copy of the corresponding file will be left with the extension .default. So, for example, if conf\httpd.conf already exists it will not be altered, but the version which would have been installed will be left in conf\httpd.conf.default. After the installation has finished you should manually check to see what in new in the .default file, and if necessary update your existing configuration files.

Also, if you already have a file called htdocs\index.html then it will not be overwritten (no index.html.default file will be installed either). This should mean it is safe to install Apache over an existing installation (but you will have to stop the existing server running before doing the installation, then start the new one after the installation is finished).

After installing Apache, you should edit the configuration files in the conf directory as required. These files will be configured during the install ready for Apache to be run from the directory where it was installed, with the documents served from the subdirectory htdocs. There are lots of other options which should be set before you start really using Apache. However to get started quickly the files should work as installed.

If you eventually uninstall Apache, your configuration files will not be removed. You will need to delete the installation directory tree (“C:\Program Files\Apache Group” by default) yourself if you do not care to keep your configuration and other web files. Since the httpd.conf file is a your accumulated effort in using Apache, you need to take the effort to remove it. The same happens for all other files you may have created, as well as any log files Apache created.

Running Apache for Windows

There are two ways you can run Apache:

  • As a “service” (tested on NT/2000 only, but an experimental version is available for 95/98). This is the best option if you want Apache to automatically start when your machine boots, and to keep Apache running when you log-off.
  • From a console window. This is the best option available for Windows 95/98 users.

Complete the steps below before you attempt to start Apache as a Windows “service”!

To run Apache from a console window, select the “Start Apache as console app” option from the Start menu (in Apache 1.3.4 and earlier, this option was called “Apache Server”). This will open a console window and start Apache running inside it. The window will remain active until you stop Apache. To stop Apache running, either press select the “Shutdown Apache console app” icon option from the Start menu (this is not available in Apache 1.3.4 or earlier), or see Controlling Apache in a Console Window for commands to control Apache in a console window.

In Apache 1.3.13 and above it is now quite safe to press Ctrl+C or Ctrl+Break to stop the Apache in the console window. And on Windows NT/2000 with version 1.3.13, Apache will also gladly stop if you select ‘Close’ from the system menu (clicking the icon on the top-left corner of the console window) or click the close (X) button on the top-right corner. The Close menu item and close (X) button also work on Windows 95/98 as of Apache version 1.3.15. But do not try any of these approaches on earlier versions of the Apache server, since Apache would not clean up.

Testing Apache for Windows

If you have trouble starting Apache please use the following steps to isolate the problem. This applies if you started Apache using the “Start Apache as a console app” shortcut from the Start menu and the Apache console window closes immediately (or unexpectedly) or if you have trouble starting Apache as a service.

Run the “Command Prompt” from the Start Menu – Programs list. Change to the folder to which you installed Apache, type the command apache, and read the error message. Then review the error.log file for configuration mistakes. If you accepted the defaults when you installed Apache, the commands would be:

 c: cd "\program files\apache group\apache" apache Wait for Apache to exit, or press Ctrl+C
