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。

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 512MB 1GB 4GB

The minimum values assumes that swap will be enabled and a non-live image is used. The No desktop value assumes that the text-based installer (not the graphical one) 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 32MB. 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.

The installer normally automatically enables memory-saving tricks to be able to run on such low-memory system, but on architectures that are less tested it may miss doing so. It can however be enabled manually by appending the lowmem=1 or even lowmem=2 boot parameter (see also 節 6.3.1.1, “Check available memory / low memory mode” and 節 5.2.1, “Debian 安裝程式的參數”).

[警告] 警告

On s390 the lowmem levels have not been tested, so automatic detection is probably outdated and you thus probably need to pass the boot parameter if your system has little memory.

Installation on systems with less memory or disk space available may be possible but is only advised for experienced users.

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.
