wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.10/pcre-8.10.zip

tar -zxf apr-1.4.5.tar.gz  
cd  apr-1.4.5  
./configure --prefix=/usr/local/apr  
make && make install 

5.安装apr util，解决APR-util not found问题

tar -zxf apr-util-1.3.12.tar.gz

./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/
make && make install

6.安装pcre，解决pcre问题
