About this book
Ubuntu Administration Masterclass is a comprehensive, progressive guide to mastering Ubuntu 22.04 administration in professional environments. From initial installation through to high availability cluster deployment, this book walks you step by step through a hands-on lab simulating a complete enterprise infrastructure.
The book is structured in three levels: Foundations (installation, filesystem, software management), Essential Administration (users, storage with LVM/RAID/ZFS, networking, security), and Advanced Mastery (DNS/DHCP/LDAP infrastructure services, high availability with HAProxy and Pacemaker, monitoring and troubleshooting).
The “lab1” environment leverages KVM to recreate a realistic infrastructure with multiple VMs (web server, database, proxy, firewall, storage, clients) and six virtual networks. Each chapter combines detailed explanations, precise commands, and real-world enterprise scenarios.
What you will learn
- Install and configure Ubuntu 22.04 Server in a virtualized KVM lab
- Navigate the Linux filesystem and manage permissions
- Administer users, groups, and privilege escalation with sudo
- Manage advanced storage: LVM, RAID with mdadm, ZFS, DRBD, and iSCSI
- Configure networking with Netplan and infrastructure services (DNS, DHCP, LDAP)
- Secure systems with AppArmor, firewalls, and best practices
- Deploy high availability clusters with HAProxy and Pacemaker
- Monitor and troubleshoot production environments
