学习编译安装httpd2.4，考虑到要和httpd2.2共存，所以安装httpd2.4时需要指定安装目录，考虑包之间的依赖关系。
apr-1.5.0.tar.bz2apr-util-1.5.3.tar.bz2（需要apr-1.5.0）httpd-2.4.9.tar.bz2 （需要pcre-devel、openssl-devel）
目录结构如下

启动httpd2.4
将httpd2.2关闭[root@adelababy bin]# service httpd statushttpd (pid 30807) is running...[root@adelababy bin]# service httpd stopStopping httpd: [ OK ]
进入httpd2.4的安装目录，启动进程，查看80端口是否启动了。
