Overview of this book

Computer virtualization is a method to enable the running of multiple application workloads on a machine to achieve efficient utilization and reduce the number of physical machines in a data center. This has now become the foundation of many modern day data centers. What began as a technology to virtualize x86 architecture has now grown beyond the limits of a server’s hardware and into the realm of storage and network virtualization. VMware is currently the market leader in developing data center virtualization solutions. This book goes into the details of designing and implementing VMware solutions that form the foundation of a VMware infrastructure. The book begins by introducing you to the concepts of server virtualization followed by the architecture of VMware’s hypervisor – ESXi and then by its installation and configuration. You then learn what is required to manage a vSphere environment and configure advanced management capabilities of vCenter. Next you are taken through topics on vSphere Networking, Storage, ESXi Clustering, Resource Management and Virtual Machine Management. You will then be introduced to SSL Certificate Management and its use in a vSphere environment. Finally, you will learn about the lifecycle management of a vSphere environment by effectively monitoring, patching and upgrading vSphere components using Update Manager. By the end of the book, you will know how to use VMware’s vSphere suite of components to lay the foundation of a modern day virtual infrastructure.

Preface

Creating additional local users on an ESXi host


It is not best practice to share the root credentials to users other than the administrator. You can either add users from the active directory, or create additional local users on an ESXi host using the vSphere Client, and assign the level of access the user will have on the ESXi host and its objects. In this topic, we will cover the procedure for creating additional local users.

By default, an ESXi host will have three default users created:

  • The vpx user: The vCenter will have an administrator's role on every ESXi host that it is configured to manage. This is achieved by creating a user called the vpxuser with the administrator role assigned to it, and this is done automatically by the vCenter managing the host.

  • The dcui user: The DCUI is severed by a process running on ESXi. The dcui user is used by DCUI to modify the locked down mode.

  • The root account: This the mandatory root account on an ESXi host.

To create a new user:

  1. Connect to the ESXi...
