Mcrypt extension not recognized by php5-fpm

[Marc-François Cochaux-Laberge]

I installed php5-fpm, php5-mcrypt and nginx.

phpinfo() tells me that mcrypt in installed, but it is impossible to use it. I get the "Laravel requires the Mcrypt PHP extension. " error message when trying to use an application made with Laravel.

I installed these packages a few times in the past and it happened only in Ubuntu 13.10.

This is duplicate of #1240590
You can fix manually using command below

Make symbolic link to ini files in mods-available
# ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available
Enable mods
# php5enmod mcrypt

Finaly, restart your php related service.

I made a typo in symbolic link command, fixed below:

Make symbolic link to ini files in mods-available
# ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/mcrypt.ini
Enable mods
# php5enmod mcrypt

Status changed to 'Confirmed' because the bug affects multiple users.

[echo (soo-yy)]

I'm using ubuntu 14.04 LTS, PHP 5.5.9.

I can't find the conf.d folder under /etc/php5/ .

The following works for me:

Create a new file mcrypt.ini under /etc/php5/mods-available/

Enter this line in mcrypt.ini:
extension=mcrypt.so

Enable mods
$ php5enmod mcrypt

Restart Apache2

Now the warning about missing Mcrypt PHP extension is gone.
