How to resolve Mcrypt extension is missing in Ubuntu 14.04 ?

When I was login to phpmyadmin, then I saw the message "mcrypt extension missing"

Try following command:

$ sudo updatedb 
$ locate mcrypt.ini

It will show you located at /etc/php5/mods-available

Now locate mcrypt.so

$ locate mcrypt.so

It will show you the following output:

/usr/lib/libmcrypt.so.4
/usr/lib/libmcrypt.so.4.4.8
/usr/lib/php5/20121212/mcrypt.so

Now write this command:

$ sudo php5enmod mcrypt

Verify that new files exists here:

ls -al /etc/php5/cli/conf.d/20-mcrypt.ini
ls -al /etc/php5/apache2/conf.d/20-mcrypt.ini

lrwxrwxrwx 1 root root 31 Mar 21 11:00 /etc/php5/cli/conf.d/20-mcrypt.ini -> ../../mods-available/mcrypt.ini

lrwxrwxrwx 1 root root 31 Mar 21 11:00 /etc/php5/apache2/conf.d/20-mcrypt.ini -> ../../mods-available/mcrypt.ini

If it does not show you the output then do the following, Create symbol links now

$ sudo ln -s /etc/php5/mods-available/mcrypt.ini /etc/php5/cli/conf.d/20-mcrypt.ini
$ sudo ln -s /etc/php5/mods-available/mcrypt.ini /etc/php5/apache2/conf.d/20-mcrypt.ini

Restart Apache

$ sudo service apache2 restart

All done! Now you will not see any issue related with mcrypt extension missing after login to phpmyadmin.
