Introduction

This is a guide to installing, configuring and using MongoDB on localhost

Installation & boot configuration

• Import public key

  sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927

• Create source list file

  echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

• Install

  sudo apt-get update sudo apt-get install -y mongodb-org

• Start mongod daemon and add it as service to be started at boot time

  systemctl start mongod systemctl enable mongod

• Check that mongo server is running on port 27017

  netstat -plntu

You should see a line that reads:

tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN      2745/mongod 

Configuration

• Open mongo shell

  mongo

• Add root user to the admin db

  use admin db.createUser({user:"admin", pwd:"your_pwd_here", roles:[{role:"root", db:"admin"}]})

Restarting and connected with root user

sudo service mongod restart

mongo -u admin -p your_pwd_here --authenticationDatabase admin

Creating a db

use your_db_name

Note: immediately after this cmd, if you exec 'show dbs' you will not see the new db. Only when data is inserted into it will Mongodb consider the database to really exist.
