=======================================================

我的环境是 ubuntu 15.04 , php5.6解决办法：

sudo apt-get install php5-mcrypt
sudo php5enmod mcrypt
sudo ln-s/etc/php5/fpm/conf.d/mcrypt.ini/etc/php5/mods-available/mcrypt.ini
sudo service php5-fpm restart 
sudo service nginx restart    
# 如果使用了 apache2 请执行以下命令
sudo service apache2 restart
