I am trying to setup webserver with PHP 7 RC3 + Nginx on Ubuntu 14.04 (for test purposes).
PHP 7 RC3
Nginx
Ubuntu 14.04
I installed Ubuntu in Vagrant using
First install php-mysql
sudo apt-get install php7.0-mysql //change the version number based on the php version
then enable the module
sudo phpenmod pdo_mysql
and restart apache
sudo service apache2 restart
