Overview of this book

MongoDB is a high-performance and feature-rich NoSQL database that forms the backbone of the systems that power many different organizations. Packed with many features that have become essential for many different types of software professional and incredibly easy to use, this cookbook contains more than 100 recipes to address the everyday challenges of working with MongoDB. Starting with database configuration, you will understand the indexing aspects of MongoDB. The book also includes practical recipes on how you can optimize your database query performance, perform diagnostics, and query debugging. You will also learn how to implement the core administration tasks required for high-availability and scalability, achieved through replica sets and sharding, respectively. You will also implement server security concepts such as authentication, user management, role-based access models, and TLS configuration. You will also learn how to back up and recover your database efficiently and monitor server performance.

Preface

Configuring MongoDB for a production deployment


In this recipe, we will look at important factors that should be configured when setting up a MongoDB instance. These include MongoDB as well as operating system parameters.

Getting ready

You will need MongoDB binaries and a Linux operating system.

How to do it...

It is highly recommended by MongoDB that you choose the XFS filesystem over Ext4, especially when using the WiredTiger storage engine. It provides concurrent disk I/O, as well as extends (reduced fragmentation-based allocation of data), which provide significant performance improvement over Ext4. To create an XFS-based volume, simply do the following:

  1. Install XFS tools:
apt-get install xfsprogs
  1. Create the XFS filesystem:
mkfs.xfs /dev/<device-name>
  1. Always choose an SSD over a mechanical disk. Additionally, make sure you measure the disk's performance using either the mongoperf utility, as shown in the Measuring disk I/O performance with mongoperf recipe in Chapter 3, Performance Tuning...
