Use the correct version of Windows

First a word about compatibility: Apache 2 will not run on Windows 95; it will barely run on Windows 98, but not Used as a service. Starting from version 4.3, PHP no longer supports Windows 95. Therefore, your Windows operating system must be Windows NT, 2000 or XP.

Apache 2: Source code or binary?

If you have Visual C++ 5.0 or higher, or have Microsoft Visual Studio installed, then although you can use the source code Generate Apache, but please never do this. In the Visual Studio IDE, the build process under Windows is very complicated. Even compiling from the command line is definitely not an easy task. So, unless you like creating makefiles, it's best to get a copy of the Windows Installer binary distribution, which is an .msi file. Only when you know enough about Apache and know what customization operations you want to perform can you consider generating (compiling) Apache yourself.

If you have installed and running an old version of Apache, you must first stop it and uninstall it before you can start installing the new server. Multiple versions of Apache 2 cannot coexist.

Double-click the Apache 2 .msi file. After agreeing to the license agreement, set the Network Domain and Server Name correctly (if you do not plan to install Apache to a remote computer, then set localhost), enter your email address in the Administrator's Email Address field, and keep port 80/Service The selected state of the option radio button. If you choose Typical installation in the next dialog box, you can quickly get a working server environment.
