mcrypt.ini doesn't exist in my directory

Question

I'm using ubuntu 13.10. I need mcrypt extention on my terminal. My server already have installed it. I follow this question and lunchpad.
So I execute this commant:

sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available
sudo php5enmod mcrypt
sudo service apache2 restart 

But when I try to above second line sudo php5enmod mcrypt command, Then I see a warning:

WARNING: Module mcrypt ini file doesn't exist under /etc/php5/mods-available.

How can I solve this problem?

Solution

Command:

sudo apt-get install mcrypt php5-mcrypt
