Based on the foundation laid out by the first edition and second edition, this book, Mastering Proxmox, Third Edition, brings updated information and details of the new features of Proxmox VE 5.0. Since the first edition of this book was published, Proxmox has been through many changes. With this third edition, I am confident that readers will be able to upgrade their skills while building and managing even better Proxmox clusters. This book shows the inner workings of Proxmox, including virtual network components, shared storage systems, the Proxmox firewall, high availability, and other features.
Chapter 1, Understanding Proxmox VE and Advanced Installation, introduces Proxmox VE in general and shows the advanced options available during installation.
Chapter 2, Creating a Cluster and Exploring the Proxmox GUI, explains how to create a cluster and shows the layout of the graphical user interface.
Chapter 3, Proxmox under the Hood, explains the Proxmox directory structure and configuration files.
Chapter 4, Storage Systems, explains how Proxmox interacts with storage and various supported storage systems.
Chapter 5, Installing and Configuring Ceph, shows how to deploy and configure a fully functional Ceph cluster along with Proxmox.
Chapter 6, KVM Virtual Machines, covers creating and managing KVM-based virtual machines.
Chapter 7, LXC Virtual Machines, covers creating and managing LXC containers.
Chapter 8, Network of Virtual Networks, explains the different networking components used in Proxmox to build virtual networks.
Chapter 9, The Proxmox VE Firewall, explains the built-in firewall feature of Proxmox.
Chapter 10, Proxmox High Availability, explains the high availability or redundancy feature of Proxmox and how to configure it.
Chapter 11, Monitoring the Proxmox Cluster, shows how to configure the Zabbix-based network monitoring option.
Chapter 12, Proxmox Production-Level Setup, explains different components in a production-level setup.
Chapter 13, Back Up and Restore Virtual Machines, explains the backup and restore features of Proxmox for disaster planning.
Chapter 14, Updating/Upgrading Proxmox, explains how to keep a Proxmox cluster up to date.
Chapter 15, Proxmox Troubleshooting, lists real incidents that may arise in a Proxmox cluster, with solutions.
Chapter 16, Rescuing Proxmox, shows ways to rescue a Proxmox cluster should a disaster occur.
Since we will be working with a Proxmox cluster throughout the book, it will be extremely helpful to have a working Proxmox cluster of your own. A very basic cluster of two to three nodes, along with a storage node, will do just fine. If learning to implement Ceph in a Proxmox cluster, then a small cluster of two or three nodes for Ceph will also be extremely helpful.
This book is for readers who want to build and manage a virtual infrastructure based on Proxmox as the hypervisor. Whether the reader is a veteran in the virtualized industry but has never worked with Proxmox, or somebody is just starting out on a promising career in this industry, this book will serve them well. Due to the advanced nature of this book, prior conceptual knowledge of server virtualization, networking, and hypervisors is required.
In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning. Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The keyring that we need to copy is located in /priv/ceph.client.admin.keyring."
A block of code is set as follows:
allow-vmbr1 ens21
iface ens21 inet manual
ovs_type OVSPort
ovs_bridge vmbr1Any command-line input or output is written as follows:
# apt-get install openvswitch-switchNew terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Open vSwitch bridge and interface under the Create tab of the Network menu of the node."
