Installing is one thing. Enabling is another. Please make sure your /etc/php.inifile contains the following line :
安装是一回事。启用是另一回事。请确保您的/etc/php.ini文件包含以下行：
extension=mcrypt.so
If you can't find your php.ini, create a test.phpfile containing :
如果找不到您的php.ini，请创建一个test.php包含以下内容的文件：
<?php phpinfo(); ?>
Execute it with php test.php | grep ".ini", and you'll find the paths to your ini files. One of them must include the extension=line above.
用 执行它php test.php | grep ".ini"，你会找到你的 ini 文件的路径。其中之一必须包括extension=上面的行。

You may have to enable the module. On Ubuntu systems this can most easily be done by linking the inifile that ships with php5-mcryptinto your conf.dfor each PHP binary you want to use:
您可能必须启用该模块。在 Ubuntu 系统上，这可以通过将ini随附的文件链接php5-mcrypt到您conf.d要使用的每个 PHP 二进制文件中来轻松完成：
sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/cli/conf.d/mcrypt.ini
sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/cgi/conf.d/mcrypt.ini
