linux下apache+php安装常见问题
configure: error: Unable to find libgd.(a|so)
如果使用的是ubuntu或debian就很简单了，直接sudo apt-get install apache2
libapache2-mod-php5 php5 php5-gd 就基本上搞定，但是用源代码安装还是很麻烦～
wget http://www.boutell.com/gd/http/gd-2.0.11.tar.gz
tar zxvf gd-2.0.11.tar.gz
cd gd-2.0.11
sudo ./configure --prefix=/usr/local/gd2
sudo make
sudo make install
再php:~/:./configure …… --with-gd=/usr/local/gd2 ……
