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

Answer 1

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

Answer 2

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.

Answer 3

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

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
