Chapter 2 Apache
2.1 Introduction
Apache is the world's top Web server. According to Netcraft, a famous Web server survey company, more than 50% of the world's Web servers are using Apache.
　　
Apache provides a variety of functions for our 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. Along with the power of free software development, we have reason to believe that the future of Apache is bright.
　　
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. Apache is the most widely used Web server software today. This chapter describes how to configure Apache servers. 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.
　　
2.2 Required System Resources
2.2.1 configuration file:
　　
File Source
　　
/Etc/httpd/conf/httpd. conf apache-1.3.12-2.i386.rpm
　　
/Etc/httpd/conf/access. conf apache-1.3.12-2.i386.rpm
　　
/Etc/httpd/conf/srm. conf apache-1.3.12-2.i386.rpm
　　
2.2.2 related tools:
　　
File Source
　　
/Etc/rc. d/init. d/httpd apache-1.3.12-2.i386.rpm
　　
2.3 configuration Scheme
There are three files related to Apache configuration:
　　
/Etc/httpd/conf/httpd. conf main configuration file
　　
Purpose: Define the setting value of the HTTP protocol and the operations on the server, and define the directories of the three files.
　　
Instance:
　　
ServerType standalone
　　
# Define the WebServer startup method as standalone to enhance its responsiveness to a large number of accesses in a timely manner
　　
ServerRoot "/etc/httpd"
　　
# Specify the directory containing httpd server files
　　
LockFile/var/lock/httpd. lock
　　
PidFile/var/run/httpd. pid
　　
ScoreBoardFile/var/run/httpd. scoreboard
　　
Timeout 300
　　
# Response timeout, in seconds
　　
KeepAlive On
　　
# Allow users to establish permanent connections
　　
MaxKeepAliveRequests 100
　　
KeepAliveTimeout 15
　　
MinSpareServers 5
　　
# Minimum number of idle server processes to be retained
　　
MaxSpareServers 20
　　
# Maximum number of idle server processes to be retained
　　
StartServers 8
　　
# Number of daemon processes at system startup
　　
MaxClients 150
　　
# The maximum client number that can provide services. Parts greater than this number are placed in the Request queue.
　　
MaxRequestsPerChild 100
