1. The first difference is in the CD contents. The "Server" CD avoids including what Ubuntu considers desktop packages (packages like X, Gnome or KDE), but does include server related packages (Apache2, Bind9 and so on). Using a Desktop CD with a minimal installation and installing, for example, apache2 from the network, one can obtain the exact same result that can be obtained by inserting the Server CD and installing apache2 from the CD-ROM. (服务器版本的安装包内含服务器基础应用,例如 Apache2, Bind9;而桌面版本的安装包则包含Gnome,KDE, X 等应用)
2. The Ubuntu Server Edition installation process is slightly different from the Desktop Edition. Since by default Ubuntu Server doesn't have a GUI, the process is menu driven, very similar to the Alternate CD installation process. (安装的过程不同,服务器版本由于没有图形界面,安装的过程是通过菜单选项来进行的。这个我们接下去会接触到)
3. Before 12.04, Ubuntu server installs a server-optimized kernel by default. Since 12.04, there is no difference in kernel between Ubuntu Desktop and Ubuntu Server since linux-image-server is merged into linux-image-generic. (12.04 之前的服务器版本是使用了服务器优化的内核的,而12.04之后,桌面版和服务器版本的内核就没有什么区别了。)
4. For Ubuntu LTS releases before 12.04, the Ubuntu Desktop Edition only receives 3 years of support. This was increased to 5 years in Ubuntu LTS 12.04 In contrast, all Ubuntu LTS Server Edition releases are supported for 5 years.(12.04之前的桌面版只有3年的支持服务,而所有的服务器版本都拥有5年的支持更新服务。)
