Can't use PHP extension Mcrypt in Ubuntu 13.10 (Nginx, PHP-FPM)

This question already has an answer here:

I installed a fresh Ubuntu 13.10 on my laptop. Like I usually do, I install the packages I need for Web development, which are nginx, php5-fpm, mysql, php5-mysql, php5-mcrypt and a few others.

After editing some configuration files, this usually works.

But today, since 13.10, an error appears instead of the Web page I expected.

Laravel requires the Mcrypt PHP extension. 

The package php5-mcrypt has been installed and reinstalled.

The command php -m doesn't seem to show mcrypt.

Any idea where the problem could come from? I've done this setup many times and it always worked.

I had the same problem after I upgraded to 13.10 this evening. Apparently this is a genuine Ubuntu 13.10 bug: “phpmyadmin do not recognize php5-mcrypt”. The PHP modules got moved from the conf.d directory to the mods-available directory, and the mcrypt module got left behind.

To fix it I put a symlink to the mcrypt.ini file in the PHP config.


If you use Apache (rather than php-fpm):

sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/apache2/conf.d/20-mcrypt.ini
sudo service apache2 restart


Or for php-fpm (rather than Apache):

  1. Make symbolic link to ini files in mods-available

    sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/mcrypt.ini
  2. Enable mods

    sudo php5enmod mcrypt
  3. Restart FPM

    sudo service php5-fpm restart
