-1.安装前电脑上要装有g++，否则安装过程会出现错误。
0.下载httpd并解压
在解压后的文件夹里面有一个srclib文件夹，下面用到的apr, apr-util,pcre应该都在里面，要用这些安装，不要从网上下，因为可能出现版本不兼容的问题。如果srclib里面没有这些软件，那么在apache官网上找到httpd***deps***的压缩包，意思就是问安装httpd所用到的信赖文件，用里面的进行安装。如果这个包再没有，那就只能从网上下了。
1、安装apache APR
./configure --prefix=/usr/local/apr
make
make test
make install
2、安装apr-util
./configure --prefix=/usr/local/apr-util/ --with-apr=/usr/local/apr/bin/apr-1-config
make
make install
3、安装pcre
./configure --prefix=/usr/local/pcre --with-apr=/usr/local/apr/bin/apr-1-config
make
make install
4、安装httpd（红色的配置是必须要配置的）
./configure --prefix=/usr/local/apache/httpd --with-apr=/usr/local/apr/
--with-apr-util=/usr/local/apr-util/bin/apu-1-config
--with-pcre=/usr/local/pcre/bin/pcre-config
make
make install
