httpd2.4之编译安装及配置参数详细说明

一，安装环境描述

   VMware workstation 10,CentOS 6.5 64位，强烈建议系统中事先安装开始工具包“Development Tools”，以免在编译安装httpd软件是出现错误（介绍就这么多， Let's go....^_^）

二，httpd新性性介绍

           1,MPM支持在运行时动态装载(Multipath Process Module)

           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,日志粒度更细
           5，每请求配置：,
           6,增强版的表达式分析器
           7，毫秒级的keepalive timeout，2.2版本的为秒级别的keepalive timeout
           8,基于FQDN的虚拟主机不再需要NameVirtualHost指令
           9，支持使用自定义变量
           新增的模块，mod_proxy_fcgi,mod_ratelimit,mod_request,mod_remoteIP
           对于基于IP的访问控制做了修改，不再支持使用order allow,deny这些机制，而是统一使用require进行

三，具体的安装与配置

   httpd2.4版本更高版本的apr及apr-util具体相关的包下载地址为：

   apr-1.5.0下载地址：http://mirror.bit.edu.cn/apache//apr/apr-1.5.0.tar.bz2

   apr-util-1.5.3下载地址：http://mirrors.cnnic.cn/apache//apr/apr-util-1.5.3.tar.bz2

   httpd-2.4.9下载地址：http://mirrors.cnnic.cn/apache//httpd/httpd-2.4.9.tar.bz2

   1,编译解压安装apr

       1）编译配置安装路径

       2）编译及安装

       3）安装成功并查看安装文件

2，解压配置编译安装apr-tuil包

       1）配置安装路

       2）编译及安装

       3）安装成功及查看安装文件

3，配置编译安装httpd-2.4.9

       1）配置安装路径及指定相关参数

       2）编译及安装

       3）安装成功及查看安装路径文件

       4）配置httpd头文件链接地址方便其它程序编译安装时使用  

       5）停止之前rpm包安装的httpd软件，如果没有安装可以忽略此步骤

       6）修改服务启动脚本

#!/bin/bash
#
# httpd        Startup script for the Apache HTTP Server
#
# chkconfig: - 85 15

    killproc -p ${pidfile} -d ${STOP_TIMEOUT} $httpd

exit $RETVAL

       7）修改/etc/httpd/httpd.conf为配置启动脚本做准备  

       8）增加httpd可执行文件的查找路

       9）启动服务及查看安装httpd的安装版本

       10）查看默认加载的模块信息

       11）打开浏览器查看是否安装成功，如下图所示

   至此，httpd-2.4.9已经安装成功

四，配置文件参数解析与配置(/etc/httpd/httpd.conf,/etc/httpd/extra/httpd-vhosts.conf）

文件/etc/httpd/httpd.conf部分

   1，默认端口的配置与修改

文件/etc/httpd/extra/httpd-vhosts.conf部分

五，HTTPS配置样例参考与实现

六，LAMP编译安装实现（memcache）

七，LAMP编译安装实现(fastCGI/php-fpm)
