install mongo:
this should be automatically done
//start by adding apt-key for downloading mongo $ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10
//get list of download for the future download $ echo 'deb http://downloads-distro.mongodb.org/repo/debian-sysvinit dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list
// update and upgrade $ sudo apt-get update $ sudo apt-get upgrade
//install $ sudo apt-get install mongodb-org
// restart mongo $ sudo /etc/init.d/mongod restart
//test mongo and set good db $ mongo $ show dbs $ use festitime $ exit
that's what you really need:
//install the MongoDB driver for PHP $ sudo pecl install mongo
//give php.ini the extension of mongo $ sudo nano /etc/php5/cli/php.ini $ sudo nano /etc/php5/apache2/php.ini
//paste this line at the end of the file extension=mongo.so
