在安装apache之前第一次我是这么安装apr和apr-util的：

#cd  /usr/local/src/
#ls

# cd apr-1.3.8/
#./configure --prefix=/usr/local/apr

# make && make install

#cd ../ apr-util-1.3.9/

#./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/bin/apr-1-config --with-lib=/usr/local/apr/lib
#make && make install

重新安装之后：

apr-1.3.8]#./configure
apr-1.3.8]#make && make install
 apr-util-1.3.9]# ./configure --with-apr=/usr/local/apr/bin/apr-1-config --with-lib=/usr/local/apr/lib
 apr-util-1.3.9]# make && make install

看看这两次的安装有什么区别吗？

首次安装apr和apr-util的时候分别指定了安装路径，这样做是错误的，apr-util本身就是apr的一个插件，需要与apr安装到一起
