编译时依然使用2.2/2.4基础标准，apr、apr-util、pcre需要安装
./configure--prefix=/opt/sudytech/apache2 --enable-so --enable-mods-shared=most--with-mpm=worker --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util--with-pcre=/usr/local/pcre/bin/pcre-config --enable-ssl--with-ssl=/usr/local/openssl --with-included-apr --enable-proxy=shared--enable-proxy-ajp=shared --enable-proxy-balancer=shared--enable-speling=shared
添加虚拟主机时，需注意proxypass后IP需有/结尾
