MongoDB 4 Quick Start Guide

By: Doug Bierer

Overview of this book

MongoDB has grown to become the de facto NoSQL database with millions of users, from small start-ups to Fortune 500 companies. It can solve problems that are considered difficult, if not impossible, for aging RDBMS technologies. Written for version 4 of MongoDB, this book is the easiest way to get started with MongoDB. You will start by getting a MongoDB installation up and running in a safe and secure manner. You will learn how to perform mission-critical create, read, update, and delete operations, and set up database security. You will also learn about advanced features of MongoDB such as the aggregation pipeline, replication, and sharding. You will learn how to build a simple web application that uses MongoDB to respond to AJAX queries, and see how to make use of the MongoDB programming language driver for PHP. The examples incorporate new features available in MongoDB version 4 where appropriate.

Simple backup and restore

Command summary (from the command line):

mongodump
mongorestore

Hopefully there is no need to stress how important it is to maintain a regular backup schedule. That being said, it is worth mentioning that doing a simple restore can actually cause problems in a properly constructed system of replicas or shards (covered later on in this chapter). In this section, we will address a simple backup of the MongoDB database that's residing on a single server.

mongodump

A backup can be as simple as issuing the command mongodump. This command will create a binary export of either a mongod or a mongos instance. Here is the output for the MongoDB instance, which is used to demonstrate concepts in this...
