Apache是一个基金会的名字，httpd才是我们要安装的软件包，早期它的名字就叫apache
apr和apr-util是一个通用的函数库，它让httpd可以不关心底层的操作系统平台，可以很方便地移植（从linux移植到windows）
下载包
# cd /usr/local/src/

# wget http://oss.aliyuncs.com/aliyunecs/onekey/apache/apr-1.5.0.tar.gz

解压软件包
# tar -zxvf httpd-2.4.10.tar.gz
# tar -zxvf apr-1.5.0.tar.gz
# tar -zxvf apr-util-1.5.3.tar.gz
# cp -rf apr-1.5.0 httpd-2.4.10/srclib/apr
# cp -rf apr-util-1.5.3 httpd-2.4.10/srclib/apr-util
# cd /usr/local/src/httpd-2.4.10
# yum install gcc -y
# ./configure --prefix=/usr/local/httpd --with-mpm=prefork --enable-so --enable-rewrite --enable-mods-shared=all --enable-nonportable-atomics=yes --disable-dav --enable-deflate --enable-cache --enable-disk-cache --enable-mem-cache --enable-file-cache --enable-ssl --with-included-apr --enable-modules=all --enable-mods-shared=all
如果有报错参考如下
--prefix 指定安装到哪里， --enable-so 表示启用DSO [1] --enable-deflate=shared 表示共享的方式编译deflate，后面的参数同理
