官网http://httpd.apache.org/download.cgi下载apache源码包后
/*解包*/
gzip -d httpd-2_x_NN.tar.gz
tar -xf httpd-2_x_NN.tar /*编译并安装*/
cd httpd-2_x_NN
./configure --prefix=/usr/local/apache2 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-so --enable-dav --enable-mainer-mode --enable-rewrite
make make install
编译apache出现的问题：configure: error: APR not found . Please read the documentation
下载APR包并解包(http://archive.apache.org/dist/apr/)
./configure --prefix=/usr/local/apr
make
sudo make install
同理解决APR-util not found问题，上面同一连接下载APR-util包并解压
./configure --prefix=/usr/local/apr-util -with-apr=/usr/local/apr
make sudo make install
pcre缺失问题，可直接通过源安装
apt-get install libpcre3-dev
也可以像上面那样编译安装，下载链接(http://sourceforge.net/projects/pcre/files/pcre/)
./configure --prefix=/usr/local/pcre
make
sudo make install
编译时若提示error: You need a C++ compiler for C++ support.说明系统没有C/C++编译环境，使用以下环境安装：
sudo apt-get install build-essential
编译apache出现make[2]: *** [exports.lo] 错误 1
将apr和apr-util源码复制到apache源码的srclib文件夹中，并分别以apr和apr-util命名，configure后面加上--with-included-apr，并重新make
//
./configure --prefix=/usr/local/apache2 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --with-included-apr
//
重新configure编译有时候经常出现一些莫名其妙的报错，这时候可以尝试make clean清理原来的configure，重新编译
安装完成后，执行如下命令启动apache
sudo /usr/local/apache2/bin/apachectl start
