mCrypt not present after Ubuntu upgrade to 13.10

Question

After I have upgraded my system from Ubuntu 13.04 to 13.10 several problems have occurred with apache, mysql and php configurations.

I solved most of them but I can't seem to get mCrypt library working. Package is installed so i don't need to apt-get it. Server works and everything seems fine, but when I try to run php artisan serve with Laravel 4, I get a message that mCrypt is required.

I did php --ri mcrypt and the output was Extension 'mcrypt' not present. I have tried putting extension=mcrypt.so to /etc/php5/apache2/php.ini but it didn't work.

Any ideas?

Output of dpkg --get-selections | grep php5

libapache2-mod-php5         install
php5                        install
php5-cli                    install
php5-common                 install
php5-gd                     install
php5-json                   install
php5-mcrypt                 install
php5-mysql                  install
php5-readline               install

Are you sure it's installed `dpkg --get-selections | grep php5` — tlenss, Oct 18 '13 at 10:05
I have updated question with output of @tlenss command. `sudo apt-get install php5-mcrypt` outputs that it is installed and newest version — Vuk Stanković, Oct 18 '13 at 10:12

I think I found the solution at launchpad.net.

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

This worked for me.

Thanks for this answer, in OpenCart 1.5.6 this issue was causing the error... Fatal error: Call to undefined function mcrypt_create_iv() in //system/library/encryption.php on line 8 – AndyGaskell Nov 01 '13 at 10:08
Of note, this solution did not work for me with Laravel/Artisan until I **also** sym-linked in /etc/php5/cli/conf.d – David M Mar 19 '14 at 13:50
I am getting this error.Which code i have to update?In which file i need to update?Kindly suggest.. – user2089987 Mar 21 '14 at 12:54
This was causing Webgility not to sync. Installing it fixed it up right nice. Thanks! – Ryan Apr 09 '14 at 13:38
Works with Laravel !‌Thank you <3 – Mehdi Maghrouni Apr 30 '14 at 20:43
in the case of Ubuntu 14.04/PHP5.5 this will need to be `sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/a pache2/mods-available` just a heads up. – ehime Jun 10 '14 at 19:17

With Ubuntu 14.04/PHP5.5 the first line is not needed. php5enmod makes the link. – Wolk Oct 04 '14 at 00:03

This is what worked for me, I have PHP Version 5.5.9-1ubuntu4.4, and I didn't have a /etc/php5/conf.d directory. – flcoder Oct 19 '14 at 16:21

I also have this problem with Ubuntu 14.04 after install.

First enable the mcrypt

sudo gedit /etc/php5/apache2/php.ini

Add this command in any line

extension=mcrypt.so

Create conf.d folder in /etc/php5

sudo mkdir conf.d

And inside that folder create mcrypt.ini file

sudo gedit mcrypt.ini

Then add this command to that file

extension=mcrypt.so

Then create a link to file

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

Enable mcrypt module

sudo php5enmod mcrypt

Restart apache

sudo service apache2 restart

You don't need `extension=mcrypt.so` in `php.ini`. It's working also without it, as php extensions (like mcrypt) are in separate `.ini` files. – machineaddict Aug 12 '14 at 10:39
@machineaddict For me adding the 'extension=mcrypt.so' worked after installing the mcrypt. Lubuntu 14.04 Trusty Thar. I was not automatically loaded – Clain Dsilva Apr 23 '15 at 04:49

From Ubuntu 13.10 to 14.04:

sudo php5enmod mcrypt
sudo service apache2 restart

Works for me.

For me: `WARNING: Module mcrypt ini file doesn't exist under /etc/php5/mods-available`. However, the file was located somewhere else. `sudo cp /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/` and ran the commands above.

I also had this problem with Ubuntu 14.04 and Nginx,but the tip for me was restart the FPM service, so I did:

Install the library

apt-get install php5-mcrypt

Find the path

updatedb && locate mcrypt.so

Set the path of mcrypt.so inside the mcrypt.ini file located in /etc/php5/mods-available/mcrypt.ini

extension=/usr/lib/php5/20121212/mcrypt.so

And then restart the FPM service

service php5-fpm restart

I just needed to apt-get install php5-mcrypt and than service php5-fpm restart on my ubuntu 14.04. – deanpodgornik May 17 '16 at 11:06
Nice..In my case in needed to find the mcrypt lib manually because the extension was empty in the mcrypt.ini file. – Deric Lima May 18 '16 at 10:17

Another solution if the package is already installed:

sudo aptitude reinstall php5-mycript

This worked for me after doing upgrade

I had the same problem with PHP 5.5.14 running on Mac OS X Yosemite. I was trying to install Laravel 5.0. And when I tried to create a new project I got an error like below (even when I tried to start the laravel server with php artisan serve

Alejandros-MacBook-Pro:Documents Lexynux$ laravel new blog
Crafting application...
PHP Notice:  Use of undefined constant MCRYPT_RIJNDAEL_128 - assumed 'MCRYPT_RIJNDAEL_128' in /Library/WebServer/Documents/blog/config/app.php on line 83

So I just added the line below at the end of my php.ini file with the nano editor:

extension=mcrypt.so
sudo nano /etc/php.ini

Finally just restart the Terminal and restart the laravel app server with

php artisan serve

And it works fine!

just found on php.net

Note, for Ubuntu, simply installing php5-mcrypt did not get mcrypt to work. You need to execute the following commands as root to enable it:

apt-get install php5-mcrypt
mv -i /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/
php5enmod mcrypt
service apache2 restart

Sometimes, this "problem" occurs because you entered an artisan command on your local machine instead of on your virtual machine. If you are using Homestead, mcrypt is already installed. Consider it a reminder to homestead ssh
