Год издания: 2025 Автор: Hemmingsson Mattias / Хеммингссон Маттиас Издательство: BPB Publications ISBN: 978-93-65897-883 Язык: Английский Формат: PDF (Not True)/EPUB Качество: Издательский макет или текст (eBook) Интерактивное оглавление: Да Количество страниц: 365 Описание: Ubuntu, a powerful and versatile Linux operating system, is the cornerstone for countless personal desktops, robust servers, and cutting-edge cloud deployments. The Ubuntu System Administration Guide provides a rapid yet comprehensive journey, equipping you with the practical skills to confidently navigate and master this essential ecosystem, from basic commands to advanced infrastructure. This book systematically builds your expertise, starting with Ubuntu's ecosystem, installation, and desktop configuration, including diverse window managers and essential networking like VPNs. You will then cover virtualization with KVM and Vagrant, followed by modern containerization using Docker and local Kubernetes (Minikube). The book transitions to server mastery, covering various installation methods, robust health checks, and advanced server networking, including firewalls and VPN servers. It progresses to professional server virtualization with KVM and the deployment of full Kubernetes clusters. Finally, you will learn to set up web servers, deploy diverse applications, and automate tasks with powerful CI/CD pipelines, embodying DevOps practices. Upon completing this practical guide, you will possess a profound understanding of Ubuntu, gaining both beginner-friendly competence and professional-level skills in system administration, modern application deployment, and automation, ready to tackle real-world challenges. What you will learn ● Learn Ubuntu installation, desktop configuration, and network security essentials. ● Implement desktop virtualization (KVM, Vagrant) and local containerization (Docker, Minikube). ● Deploy Ubuntu Server on metal, cloud, and configure advanced networking. ● Build production Kubernetes clusters, including master, workers, and services. ● Automate server deployments and service delivery via CI/CD pipelines. ● Troubleshoot server logs, implement security HIDS, and set up alerts. Who this book is for This book is perfect for aspiring system administrators, developers, DevOps engineers, and IT professionals. Readers should have basic computer literacy and a desire to learn, as it guides them from fundamental Ubuntu concepts to advanced server and cloud-native practices. Ubuntu, мощная и универсальная операционная система Linux, является краеугольным камнем для бесчисленных персональных компьютеров, надежных серверов и передовых облачных решений. Руководство по системному администрированию Ubuntu представляет собой краткое, но всестороннее руководство, которое поможет вам овладеть практическими навыками, необходимыми для уверенной навигации и освоения этой важной экосистемы, от базовых команд до продвинутой инфраструктуры. Эта книга систематизирует ваши знания, начиная с экосистемы Ubuntu, установки и настройки рабочего стола, включая различные оконные менеджеры и основные сетевые сервисы, такие как VPN. Затем вы познакомитесь с виртуализацией с помощью KVM и Vagrant, а затем с современной контейнеризацией с использованием Docker и локального Kubernetes (Minikube). В книге рассказывается о различных методах установки, надежных проверках работоспособности и расширенных серверных сетях, включая брандмауэры и VPN-серверы. Затем вы перейдете к профессиональной виртуализации серверов с помощью KVM и развертыванию полноценных кластеров Kubernetes. Наконец, вы научитесь настраивать веб-серверы, развертывать разнообразные приложения и автоматизировать задачи с помощью мощных конвейеров CI/CD, воплощающих методы DevOps. После прочтения этого практического руководства вы будете обладать глубоким пониманием Ubuntu, приобретете как навыки, понятные новичкам, так и навыки профессионального уровня в области системного администрирования, развертывания современных приложений и автоматизации, и будете готовы решать реальные задачи. Что вы узнаете ● Изучите установку Ubuntu, настройку рабочего стола и основы сетевой безопасности. ● Реализуйте виртуализацию рабочего стола (KVM, Vagrant) и локальную контейнеризацию (Docker, Minikube). ● Разверните сервер Ubuntu в metal, cloud и настройте расширенную сеть. ● Создавайте производственные кластеры Kubernetes, включая основные, рабочие и службы. ● Автоматизируйте развертывание серверов и предоставление услуг с помощью конвейеров CI/CD. ● Устраняйте неполадки в журналах сервера, внедряйте идентификаторы безопасности и настраивайте оповещения. Для кого предназначена эта книга Эта книга идеально подходит для начинающих системных администраторов, разработчиков, инженеров DevOps и ИТ-специалистов. Читатели должны обладать базовой компьютерной грамотностью и желанием учиться, поскольку она поможет им перейти от фундаментальных концепций Ubuntu к передовым серверным и облачным практикам.
