Ubuntu 15.04 Server with systemd: Administration and Reference (2015)


This book is designed as an Ubuntu 15.04 Server administration and reference source, covering the Ubuntu servers and their support applications. Server tools are covered as well as the underlying configuration files and system implementations. The emphasis is on what administrators will need to know to perform key server support and management tasks. Coverage of the systemd service management system is integrated into the book, replacing the deprecated Upstart system. Topics covered include software management, systemd service management, AppArmor security, OpenSSH, and the Network Time Protocol. Key servers are examined, including Web, FTP, CUPS printing, NFS, and Samba Windows shares. Network support servers and applications covered include the Squid proxy server, the Domain Name System (BIND) server, DHCP, distributed network file systems, IPtables firewalls, and cloud computing.

The book is organized into five parts: getting started, services, shared resources, network support, and shells.

Part 1 focuses on basic tasks such as installing the Ubuntu Server CD, managing software from the Ubuntu repository, and basic usage for the desktop and the command line interfaces.

Part 2 examines Internet servers as well as how services are managed by systemd using unit files. Configuration and implementation of the Postfix mail server, the vsftpd FTP server, the Apache Web server, as well as news and database servers are covered in detail.

Part 3 deals with servers that provide shared resources on a local network or the Internet. Services examined include the CUPS printing server, NFS Linux network file server, and Samba Windows file and printing server, the GFS distributed file system, and cloud computing services supported by Ubuntu.

Part 4 covers servers that provide network support, like the Squid proxy server, the Bind Domain Name System (DNS) server, DHCP servers, and the IPtables and FirewallD firewalls. Key networking operations are also examined like IPv6 auto-configuration, TPC/IP networking, and network monitoring tools.

Part 5 provides a review of shell commands, including those used for managing files, as well as shell scripts, variables, and configuration files. The Ubuntu Server CD only installs a command line interface, with no desktop. To manage your system and its files you will need to know the shell commands.
