25.3  Installing Apache for Windows

You need Microsoft Installer 2.0 or above for the installation to work. For Windows NT 4.0 and 2000 refer to Microsoft’s article KB 2925392 . Windows XP and later do not require this update. The Windows 98/ME installer engine appears to no longer be available from Microsoft, and these instructions no longer detail such prerequisites.

Note that you cannot install two versions of Apache 2.2 on the same computer with the binary installer. You can, however, install a version of the 1.3 series and a version of the 2.2 series on the same computer without problems. If you need to have two different 2.2 versions on the same computer, you have to compile and install Apache from the source (p. 1601).

Run the Apache .msi file you downloaded above. The installation will ask you for these things:

  1. Network Domain. Enter the DNS domain in which your server is or will be registered in. For example, if your server’s full DNS name is server.mydomain.net, you would type mydomain.net here.
  2. Server Name. Your server’s full DNS name. From the example above, you would type server.mydomain.net here.
  3. Administrator’s Email Address. Enter the server administrator’s or webmaster’s email address here. This address will be displayed along with error messages to the client by default.
  4. For whom to install Apache. Select for All Users, on Port 80, as a Service - Recommended if you’d like your new Apache to listen at port 80 for incoming traffic. It will run as a service (that is, Apache will run even if no one is logged in on the server at the moment) Select only for the Current User, on Port 8080, when started Manually if you’d like to install Apache for your personal experimenting or if you already have another WWW server running on port 80.
  5. The installation type. Select Typical for everything except the source code and libraries for module development. With Custom you can specify what to install. A full install will require about 13 megabytes of free disk space. This does not include the size of your web site(s).
  6. Where to install. The default path is C:\Program Files\Apache Software Foundation under which a directory called Apache2.2 will be created by default.

During the installation, Apache will configure the files in the conf subdirectory to reflect the chosen installation directory. However, if any of the configuration 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 be renamed as conf\httpd.conf.default. After the installation you should manually check to see what new settings are in the .default file, and if necessary, update your existing configuration file.

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

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