安装Apache httpd

http://download.chinaunix.net/ 上下载 apr,apr-util,apache-httpd。

1)安装apr，默认配置，没有问题。
2)安装apr-util，出现问题libexpat.so: could not read symbols: File in wrong format，原因是6该库是32位，而机器是64位，不兼容，解决方法：添加语句--with-expat=builtin
./configure.bak -enable-lib64 --with-apr=/usr/local/apr --with-expat=builtin
3)安装apache-httpd，默认配置，没有问题。
