Using and Administering Linux: Volume 3: Zero to SysAdmin: Network Services

Book Description

Manage complex systems with ease and equip yourself for a new career. This book builds upon the skills you learned in Volumes 1 and 2 of this course and it depends upon the virtual network and virtual machine you created there.

However, more experienced Linux users can begin with this volume and download an assigned script that will set up the VM for the start of Volume 3. Instructions with the script will provide specifications for configuration of the virtual network and the virtual machine. Refer to the volume overviews in the book’s introduction to select the volume of this course most appropriate for your current skill level.

Start by reviewing the administration of Linux servers and install and configure various Linux server services such as DHCP, DNS, NTP, and SSH server that will be used to provide advanced network services.  You’ll then learn to install and configure servers such as BIND for name services, DHCP for network host configuration, and SSH for secure logins to remote hosts. Other topics covered include public/private keypairs to further enhance security, SendMail and IMAP and antispam protection for email, using Apache and WordPress to create and manage web sites, NFS, SAMBA, and Chrony.

This volume also covers SELinux, and building RPMs to distribute automation scripts. All of these services are installed on a single server host over the course of the book and by the time you are finished you will have a single server that provides these services for your network.

What You Will Learn

• Install, configure, and manage several Linux server services such as email with spam management and single and multiple web sites
• Work with NTP time synchronization, DHCP, SSH, and file sharing with Unix/Linux and Windows clients
• Create RPMs for distribution of scripts and administrative programs.
• Understand and work with enhanced security.

Who This Book Is For

Those who are already Linux power users – SysAdmins who can administer Linux workstation hosts that are not servers – who want to learn to administer the services provided by Linux servers such as web, time, name, email, SSH, and more.

书名：使用和管理Linux：第3卷：零到系统管理员：网络服务

轻松管理复杂的系统，为新的职业生涯做好准备。本书以您在本课程第1和第2卷中学到的技能为基础，并取决于您在那里创建的虚拟网络和虚拟机。

但是，更有经验的Linux用户可以从这一卷开始，并下载一个分配的脚本，该脚本将为第3卷的开始设置VM。该脚本的说明将提供配置虚拟网络和虚拟机的规范。请参考《简介》一书中的卷概述，以选择本课程最适合您当前技能水平的卷。

从查看Linux服务器的管理开始，安装和配置各种Linux服务器服务，如用于提供高级网络服务的DHCP、DNS、NTP和SSH服务器。然后，您将学习安装和配置服务器，如用于名称服务的BIND、用于网络主机配置的DHCP和用于安全登录远程主机的SSH。其他主题包括进一步增强安全性的公钥/私钥对、Sendmail和IMAP以及对电子邮件的反垃圾邮件保护，使用Apacheand WordPress创建和管理网站、NFS、Samba和chrony。

这一卷还包括SELinux，以及构建RPM以分发自动化脚本。在本书的整个过程中，所有这些服务都安装在一台服务器主机上，当您读完时，您将拥有一台为您的网络提供这些服务的服务器。

你将学到什么

• 安装、配置和管理多种Linux服务器服务，例如带有垃圾邮件管理功能的电子邮件以及单个和多个网站
• 与Unix/Linux和Windows客户端一起使用NTP时间同步、DHCP、SSH和文件共享
• 创建RPM以分发脚本和管理程序。
• 了解增强的安全性并与之协作。

这本书是为谁写的

那些已经是Linux高级用户-可以管理非服务器的Linux工作站主机的系统管理员-希望学习管理由Linux服务器提供的服务，如Web、时间、名称、电子邮件、SSH等。
