3.4. 滿足最低的硬體要求

一旦您收集好您的電腦硬體配備的相關資料,再檢查一下您的硬體,就可以讓您如願以償的安裝系統。

基於您的需求,您也許可以用低於下面表格所列的配備安裝系統。但是,如果無視這些建議的話,多數使用者會安裝失敗。

A Pentium 4, 1GHz system is the minimum recommended for a desktop system.

表格 3.2. 建議的最低系統需求

安裝類別 RAM (minimum) RAM (recommended) 硬碟
無桌面系統 256 megabytes 512 megabytes 2 gigabytes
有桌面系統 1 gigabytes 2 gigabytes 10 gigabytes

The minimum values assumes that swap will be enabled and a non-liveCD image is used. The No desktop value assumes that the non-graphical (text-based) installer is used.

The actual minimum memory requirements are a lot less than the numbers listed in this table. With swap enabled, it is possible to install Debian with as little as 350MB. The same goes for the disk space requirements, especially if you pick and choose which applications to install; see 節 D.2, “各軟體集所需的磁碟空間” for additional information on disk space requirements.

It is possible to run a graphical desktop environment on older or low-end systems, but in that case it is recommended to install a window manager that is less resource-hungry than those of the GNOME or KDE Plasma desktop environments; alternatives include xfce4, icewm and wmaker, but there are others to choose from.

It is practically impossible to give general memory or disk space requirements for server installations as those very much depend on what the server is to be used for.

Remember that these sizes don't include all the other materials which are usually to be found, such as user files, mail, and data. It is always best to be generous when considering the space for your own files and data.

Disk space required for the smooth operation of the Debian GNU/Linux system itself is taken into account in these recommended system requirements. Notably, the /var partition contains a lot of state information specific to Debian in addition to its regular contents, like logfiles. The dpkg files (with information on all installed packages) can easily consume 40MB. Also, apt puts downloaded packages here before they are installed. You should usually allocate at least 200MB for /var, and a lot more if you install a graphical desktop environment.
