Apache provides a variety of functions for network administrators, including Directory Index, directory alias, content negotiation, configurable HTTP error report, SetUID execution of CGI program, sub-process resource management, server-side image ING, URL rewriting, URL spelling check, and online manual man. That is to say, if you have successfully installed and configured Apache on the Linux Server, your computer will also change as Apache takes effect and become a real Web Server, this change is indeed exciting.
　　
In the Internet era, the release of external homepage has become an important means to establish the company's image, and the internal homepage has become the main method of company management. However, to implement these functions, we should first configure our Linux Server as a powerful Web Server. This chapter describes how to configure the Apache server. I hope that my colleagues can read this article to achieve the goal of both theoretical practices and quickly become an outstanding network administrator in a short time.
