apr-1.4及以上版本
apr-util-1.4及以上版本
而直接升级apr和apr-util会覆盖直接版本的程序，影响其他程序的依赖关系，所以一般使用编译安装的方式安装apr和apr-util，然后编译安装httpd2.4。
具体步骤如下：
1、准备安装环境和源码包
[root@localhost ~] # yum groupinstall "Development Tools" "Server Platform Development" -y[root@localhost ~] # yum install pcre-devel -y
下载源码包，这里我用到的是：
apr-1.5.0.tar.bz2
apr-util-1.5.3.tar.bz2
httpd.2.4.9.tar.bz2
2、编译安装apr和apr-util
[root@localhost ~] # tar xf apr-1.5.0.tar.bz2[root@localhost ~] # cd apr-1.5.0[root@localhost apr-1.5.0 ] # ./configure --prefix=/usr/local/apr // 为避免影响原有版本apr，将新版本apr安装到新的目录/usr/local/apr，--prefix选项为指定安装目录[root@localhost apr-1.5.0 ] # make && make install[root@localhost ~] # tar xf apr-util-1.5.3.tar.bz2[root@localhost ~] # cd apr-util-1.5.3[root@localhost apr-util-1.5.3] # ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr// 同样将apr-util安装到新的目录，--with-apr指定apr所在目录[root@localhost apr-util-1.5.3 ] # make && make install
3、编译安装httpd2.4
[root@localhost ~] # tar xf httpd-2.4.9.tar.bz2[root@localhost ~] # cd httpd-2.4.9[root@localhost httpd-2.4.9 ] # ./configure --prefix=/usr/local/apache --sysconf=/etc/httpd24 --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=prefork// --prefix=/usr/local/apache ：安装位置// -sysconf=/etc/httpd24 ：配置文件位置// --enable-so ：支持DSO动态装载模块// --enable-ssl ：支持SSL/TLS，可实现https协议访问，需要安装openssl-devel// --enable-cgi ：支持CGI脚本// --enable-rewrite ：支持URL重写// --with-zlib ：使用指定的zlib压缩库，不指定路径会自动寻找// --with-pcre ：使用指定的pcre库，增强的正则表达式分析工具；不指定路径会自动寻找，需要安装pcre-devel// --with-apr=/usr/local/apr ：指定依赖的apr程序安装位置// --with-apr-util=/usr/local/apr-util ：指定依赖的apr-util程序安装位置// --enable-modules=most ：支持动态启用模块：all：所有；most：常用// --enable-mpms-shared=all ：编译并共享的模块// --with-mpm=event ：默认启用的mpm模块；可选项有prefork|worker|event[root@localhost httpd-2.4.9 ] # make && make install
4、安装后配置
（1）添加环境变量，并重读文件
因为是编译安装的httpd，所以PATH环境变量里并没有我们所安装的目录，需要手动添加
[root@localhost ~] # vim /etc/profile.d/httpd24.shexport PATH=/usr/local/apache/bin:$PATH[root@localhost ~] # source /etc/profile.d/httpd24.sh
添加完成后，执行httpd命令时，就可以正常使用，如果不添加到环境变量，则需要在绝对路径下使用，十分不便。
（2）导出头文件
[root@localhost ~] # ln -sv /usr/local/apache/include /usr/include/httpd
不需要复制，创建软链接即可
（3）导出man手册
[root@localhost ~] # vim /etc/man.confg
（4）编写服务脚本
[root@localhost ~]# vim /etc/rc.d/init.d/httpd#!/bin/bash## httpd Startup script for the Apache HTTP Server## chkconfig: - 85 15# description: The Apache HTTP Server is an efficient and extensible # server implementing the current HTTP standards.# processname: httpd# config: /etc/httpd/conf/httpd.conf# config: /etc/sysconfig/httpd# pidfile: /var/run/httpd/httpd.pid#### BEGIN INIT INFO# Provides: httpd# Required-Start: $local_fs $remote_fs $network $named# Required-Stop: $local_fs $remote_fs $network# Should-Start: distcache# Short-Description: start and stop Apache HTTP Server# Description: The Apache HTTP Server is an extensible server # implementing the current HTTP standards.### END INIT INFO# Source function library.. /etc/rc.d/init.d/functionsif [ -f /etc/sysconfig/httpd ]; then . /etc/sysconfig/httpdfi# Start httpd in the C locale by default.HTTPD_LANG=${HTTPD_LANG-"C"}# This will prevent initlog from swallowing up a pass-phrase prompt if# mod_ssl needs a pass-phrase from the user.INITLOG_ARGS=""# Set HTTPD=/usr/sbin/httpd.worker in /etc/sysconfig/httpd to use a server# with the thread-based "worker" MPM; BE WARNED that some modules may not# work correctly with a thread-based MPM; notably PHP will refuse to start.# Path to the apachectl script, server binary, and short-form for messages.apachectl=/usr/local/apache/bin/apachectlhttpd=${HTTPD-/usr/sbin/httpd}prog=httpdpidfile=${PIDFILE-/var/run/httpd/httpd24.pid}lockfile=${LOCKFILE-/var/lock/subsys/httpd24}RETVAL=0STOP_TIMEOUT=${STOP_TIMEOUT-10}# The semantics of these two functions differ from the way apachectl does# things -- attempting to start while running is a failure, and shutdown# when not running is also a failure.

[root@localhost ~]# chkconfig --add httpd[root@localhost ~]# chkconfig httpd on
写的比较潦草，如有遗漏错误和争议之处，欢迎大家的批评指正和讨论，谢谢。
