Linux Detailed construction httpd website construction Service (Apache)

1.HTTPD Introduction
Today's mainstream open source Web server software has httpd (Apache), lighttpd,nginx,thttpd, and so on, and httpd is so far the use of a lot of Web servers, according to statistics, the current HTTPD global share is about 47%, Although there is a decrease but the use of two is still the most, statistics Web server usage rate of the website is: http://news.netcraft.com/
httpd work principle: HTTPD is the Apache Hypertext Transfer Protocol (HTTP) server main program, is designed as a stand-alone running background process, it will establish a processing request of the child process or thread pool.
Typically httpd should not be called directly, but should be called by Apachectl in a Unix-like system and run as a service in Windows.

Version of 2.HTTPD

httpd-1.3httpd-2.0httpd-2.2httpd-2.4目前为止最新的版本是httpd-2.4.6，但是这里我用的是系统自带的RPM包安装的httpd-2.2.15版本的，最新版本配置可能会有所不同    本文主要介绍httpd的两大版本，httpd-2.2和httpd-2.4。    CentOS6系统的版本默认提供的是httpd-2.2版本的rpm包                CentOS7系统的版本默认提供的是httpd-2.4版本的rpm包

3.HTTPD Working Model

高度模块化：DSOMPM：Multipath Processing Module #多处理模块prefork:一次一个进程响应一个请求worker：一个进程生成多个线程，一个线程响应一个请求event：基于事件驱动，一个进程响应多个请求  

4.HTTPD Self-brought tool program

Tools	function
htpasswd	Basic Authentication in the file implementation, the use of the Account password generation tool
Apachectl	HTTPD comes with a service control script that supports Start,stop,restart
Apxs	Tools provided by the Httpd-devel package that extend the httpd use of third-party modules
Rotatelogs	Log Scrolling Tool
suEXEC	Temporarily switch to a user-run tool when accessing certain resources with special permissions configuration
Ab	The Apache BENCHMARK,HTTPD Stress test Tool

HTTPD program Environment for 5.RPM package installation

Files/Directories	the corresponding function
/var/log/httpd/access.log	Access log
/var/log/httpd/error_log	Error log
/var/www/html/	Site Documentation Directory
/usr/lib64/httpd/modules/	Module file path
/etc/httpd/conf/httpd.conf	Master configuration file
/etc/httpd/conf.modules.d/*.conf	Module configuration file
/etc/httpd/conf.d/*.conf	Secondary configuration files

6.HTTPD Common Configuration
#切换使用MPM (edit/etc/httpd/conf.modules.d/00-mpm.conf file)
LoadModule Mpm_name_module modules/mod_mpm_name.so
There are three types of name, namely:
Prefork
Event
Worker

Access control rules:

Law	function
Require all granted	Allow all hosts to access
Require all Deny	Deny all host access
Require IP ipaddr	Authorize host access to the specified source address
Require not IP ipaddr	Deny host access to the specified source address
Require Host HOSTNAME	Authorize host access for the specified source host name
Require not host HOSTNAME	T denies host access to the specified source host name

Note: The httpd-2.4 version defaults to deny access to all hosts, so the installation must be done to display authorized access later
Example:
<RequireAll>
Require not IP 192.168.1.20
Require all granted
</RequireAll>

There are three types of virtual hosts:
1. Different ports of the same IP
2. Same port with different IP
3. Same IP same port different domain name

7. Compile and install httpd-2.4 (the following instance is a compiled installation, same IP same port different domain name)
httpd dependent on Apr-1.4+,apr-util-1.4+,[apr-icon]
