Installation Mcrypt Extension for Laravel / Mcrypt PHP extension required.

In linux ubuntu

 sudo php5enmod mcrypt
It helped to install mcrypt. If you can not install try the following one.

The above one doesnot help you, because your PHP doesnot compiled with Mcrypt. So we need to install it now.
sudo apt-get install php5-mcrypt

The above one helps you to install mcrypt. After installing php5-mcrypt you have to make a symlink to ini files in mods-available Here is the one:
sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/mcrypt.ini

enable :
sudo php5enmod mcrypt

now restart your php5-fpm:
sudo service php5-fpm restart.

That’s it. Remember all the steps needs to restart your server to take effect.
