A guide to understanding MongoDB development and administration for NoSQL developers

What is this book about?

When it comes to managing a high volume of unstructured and non-relational datasets, MongoDB is the defacto database management system (DBMS) for DBAs and data architects. This updated book includes the latest release and covers every feature in MongoDB 4.x, while helping you get hands-on with building a MongoDB database app.

This book covers the following exciting features:

• Understand how to configure and install MongoDB 4.x
• Build a database-driven website using MongoDB as the backend
• Perform basic database operations and handle complex MongoDB queries
• Develop a successful MongoDB database design for large corporate customers with complex requirements
• Secure MongoDB database systems by establishing role-based access control with X.509 transport-level security

Instructions and Navigations

All of the code is organized into folders. For example, Chapter02.

The code will look like the following:

if (test expression)
{
  Statement upon condition is true
}

Here are the instructions for the test environment that serves for chapters 3 to 12. There are separate instructions, in the book, for testing MongoDB installation (chapter 2). Also, see chapter 13 for instructions on setting up a test environment to model a replica set. See chapter 14 for instructions on setting up a test environment to model a sharded cluster.

Set up your host computer

• Install git
  • On Linux or Mac: https://git-scm.com/book/en/v2/Getting-Started-Installing-Git
  • On Windows: https://gitforwindows.org/
• Clone the repository for the book
  • Open a terminal window (command prompt)
  • If you are running Windows, be sure to use the Git BASH shell to follow these commands
  • Change to a directory under which you wish to install the files for the book
  • Clone the repository for the book using git (substitute the target directory on your computer in place of /path/to/repo):

git clone https://github.com/packtpub/learn-mongodb-4_0 /path/to/repo

• Install docker
• Pull the Docker base image for the book

docker pull unlikelysource/mongodb_python:latest

How To Setup Test Environment

Using Docker Compose

• Install docker-compose
• Open a terminal window (or Windows GIT bash prompt)
• Change to /path/to/repo
• Bring the test environment online:

cd /path/to/repo
docker-compose up -d --build

Using Docker

• Install docker
• Create a volume learn-mongodb

docker volume create db_data_server_1

• Identify the location

docker volume ls
docker volume inspect db_data_server_1

• Run PHP for Linux image and mount the volume (replace $PWD with /path/to/repo):

docker run -d -it --name learn-mongo-server-1 -v db_data_server_1:/data/db -v $PWD:/repo -v $PWD/docker/hosts:/etc/hosts -v $PWD/docker/mongod.conf:/etc/mongod.conf unlikelysource/mongodb_python:latest

Restore the Sample Data

• Open a terminal window (or Windows GIT bash prompt)
• Change to /path/to/repo
• Get container ID

docker container ls -a

• Open a shell to the container

docker exec -it <container_ID> /bin/bash
// or
docker exec -it learn-mongo-server-1 /bin/bash

• Restore sample data

/repo/restore_data_inside.sh

• Stop / start the web server

/repo/restart_apache_inside.sh

Access the Test Server from Outside Docker

• From inside the docker container, run this command to determine the IP address:

ifconfig

• Add an entry at the end of the /etc/hosts file of your own computer as follows:
  • Substitute the IP address you discovered above if it's different from 172.16.0.11

172.16.0.11    learning.mongodb.local

• Also, append the entries from /path/to/repo/docker/hosts file onto the end of your own /etc/hosts file
• For readers using a Windows computer, the /etc/hosts file is located here:

C:\Windows\System32\drivers\etc\hosts
