昨天帮同事在服务器上安装一个php模块，在运行phpize时报出了一个错误“Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONFenvironment variable is set correctly and then rerun this script.”没有autoconf，马上安装了autoconf及imake后解决。

eAccelerator is a free open-source PHP accelerator & optimizer. It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution. 这个东西就是类似于"zend optimizer"的软件！
