Fix Mcrypt WARNING Ubuntu Server

today I faced problem in setup a mcrypt module

I did install it via

apt-get install mcrypt php5-mcrypt

when i did try to enable it via

php5enmod mcrypt

I got this error

root@ubuntu:/etc/php5/apache2/conf.d# php5enmod mcrypt
WARNING: Not enabling the mcrypt module for apache2 SAPI since module symlink
WARNING: already exists in /etc/php5/apache2/conf.d with different content.
WARNING: Not enabling the mcrypt module for cli SAPI since module symlink
WARNING: already exists in /etc/php5/cli/conf.d with different content.

to solve this unlink the 20-mcrypt.ini inside this folders

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

service apache2 restart
