cd /usr/ports/databases/mongodb/ make install
Append the following lines to /etc/rc.conf
mongod_config="/usr/local/etc/mongodb.conf" mongod_dbpath="/var/db/mongodb" mongod_enable="YES"
Reboot the machine
Now after reboot, test the configuration by connecting to the MongoDB server
The output would be like this if the server has been connected successfully
