httpd三之源码编译http2.4.9、虚拟主机、基于用户认证
本文主要讲解源码编译http2.4.9，并能实现基于虚拟主机、用户认证等实现网页访问。http2.4.9会依赖于更高版本的apr和apr-util，所有需要先对apr和apr-util进行编译
http2.4系列相对于http2.2系列新增的功能有
1) MPM支持在运行时装载
2）支持event
3）异步读写
4）在每模块及每目录上指定日志级别
5）每请求配置
6）增强版的表达式分析器
7）毫秒级的keepalive timeout
8）支持主机名的虚拟主机不在需要NameVirtualHost指令
9）支持使用自定义变量
新增的模块由mod_proxy_fcgi,mod_ratelimit,mod_request,mod_remoteip
对应IP的访问做了修改，不在使用order，allow deny这些机制，而是统一使用require进行
一、环境准备
安装好开发包组和pcre-devel工具，下载最新版的httpd、apr和apr-util，本文下载的都为最新的源码包
# yum install -y pcre-devel
# wget http://apache.fayea.com/apache-mirror//httpd/httpd-2.4.9.tar.bz2
# wget http://mirrors.hust.edu.cn/apache//apr/apr-1.5.0.tar.gz
# wget http://mirrors.hust.edu.cn/apache//apr/apr-util-1.5.3.tar.gz
二、安装apr
# tar xf apr-1.5.0.tar.gz
# cd apr-1.5.0
# ./configure --prefix=/usr/local/apr
# make && make install
三、安装apr-util
# tar xf apr-util-1.5.3.tar.gz
# cd apr-util-1.5.3
# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
# make && make install
四、编译httpd
# tar xf httpd-2.4.9.tar.bz2
# cd httpd-2.4.9
# ./configure --prefix=/usr/local/httpd --sysconfdir=/etc/httpd --enable-so --enable--ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-modeles=most --enable-mpms-shared=all --with-mpm=event
# make && make install
enable-so enable--ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre 启动so、ssl、cgi、rewrite、zlib、pcre等功能
--with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util 指定apr和apr-util的地址
--enable-modeles=most 编译常用的模块
--enable-mpms-shared=all --with-mpm=event 编译所有的mpms，并以event作为默认
1、导出头文件
root@wangfeng7399 ~]# ln -sv /usr/local/httpd/include/ /usr/include/httpd
2、导出帮助文件
在/etc/man.conf中添加
MANPATH /usr/local/httpd/man
3.导出二进制文档
# vi /etc/profile.d/http.sh
export PATH=/usr/local/httpd/bin:$PATH
测试
可以通过 apachectl start启动
准备系统启动脚本
# cat httpd
#!/bin/bash
#
# httpd Startup script for the Apache HTTP Server
#

# server implementing the current HTTP standards.

搭建基于主机名的虚拟主机
编辑配置文件
# vi httpd-vhosts.conf
<VirtualHost *:80>
ServerAdmin www.wangfeng7399.com
DocumentRoot "/www/html/wangfeng7399"
</VirtualHost>
<VirtualHost *:80>
ServerAdmin www.wangfeng17399.com
DocumentRoot "/www/html/wangfeng17399"
修改主配置文件将主记录注释掉，将辅助http-vhosts启动起来
#DocumentRoot "/usr/local/httpd/htdocs"
# Virtual hosts
Include /etc/httpd/extra/httpd-vhosts.conf
分别在/www/html/wangfeng7399和/www/html/wangfeng17399中提供网页文件，并修改其权限
在window的hosts文件中添加对两个域名的解析
