编译安装httpd-2.4.9
(一)介绍:
Apache是世界使用排名第一的Web服务器软件。它可以运行在几乎所有广泛使用的计算机平台上,由于其跨平台和安全性被广泛使用,是最流行的Web服务器端软件之一。它快速、可靠并且可通过简单的API扩充,将Perl/Python等解释器编译到服务器中。同时Apache音译为阿帕奇,是北美印第安人的一个部落,叫阿帕奇族,在美国的西南部。也是一个基金会的名称、一种武装直升机等等。
(二)安装方式|版本
安装方式(1.编译安装 2.rpm包安装)
版本(httpd-2.0 httpd-2.2 httpd-2.4最新版本)
(三)httpd2.4新特性:
1) MPM支持运行时装载
--enable-mpms-shared=all --with-mpm=prefork|worker|event
2) 支持event MPM
3) 异步读写支持
4) 支持每模块及每目录分别使用不同的日志级别
5) 支持per-request(即支持<If>, <ElseIf>, and <Else>条件判断)
6) 增强版的表达式分析器;
7) 支持毫秒级keepalive timeout;
8) 基于FQDN(域名)的虚拟主机不再需要NameVirtualHost;
9) 支持用户使用自定义变量;
新增模块:mod_proxy_fcgi, mod_ratelimit, mod_request, mod_remoteip
备注:2.4版本修改了一些配置机制:不再支持使用order, allow, deny来实现基于IP的访问控制;
(四)编译安装:
编译前:编译依赖开发环境,yum groupinstall Development tools Server Platform Development -y
编译三部曲:检查编译环境,编译,安装
编译安装apr和apr-util
tar xf apr-1.5.0.tar.bz2
cd apr-1.5.0
./configure --prefix=/usr/local/apr
make && make install
tar xf apr-util-1.5.3.tar.bz2
cd apr-util-1.5.3
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/
make && make install
编译安装httpd2.4
cd httpd-2.4.9
./configure --prefix=/usr/local/apache --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-modules=most --enable-mpms-shared=all --with-mpm=event && make && make install #编译模块

-f<设定文件> 指定配置文件。
-h 显示帮助。
-l 显示服务器编译时所包含的模块。
-L 显示httpd指令的说明。
-S 显示配置文件中的设定。
-t 测试配置文件的语法是否正确。
-v 显示版本信息。
-V 显示版本信息以及建立环境。
-X 以单一程序的方式来启动服务器。
