ln -s /usr/local/libmcrypt/lib/libmcrypt.so.4.4.8 /usr/local/lib/libmcrypt.so.4.4.8
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
2、安装mhash
tar zxvf mhash-0.9.9.9.tar.gz

export LDFLAGS="-L /usr/local/mhash/lib -I /usr/local/mhash/include/"
export CFLAGS="-I /usr/local/mhash/include/"
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
export LDFLAGS="-L/usr/local/mhash/lib -I/usr/local/mhash/include/"
export CFLAGS="-I/usr/local/mhash/include/"
4、查看PHP版本
