LINUX設置默認啓動模式 inittab

LINUX設置默認啓動模式 inittab

經過修改/etc/inittab,使系統在啓動時進入不一樣模式。

以下文 id:3:initdefault: 那一行,數字選項 3 表示系統啓動時默認進入多用戶文本模式,經過修改該數字,便可默認進入不一樣的模式。該數字選項值爲 0~6 。
注意:
0 - 表示關閉系統(千萬不要把默認設置成0哦!)
1 - 單用戶模式
2 - 多用戶模式,沒有NFS服務
3 - 多用戶文本模式
5 - 圖形模式
6 - 系統從新啓動

啓動進入多用戶文本模式後,能夠使用命令 startx 進入圖形模式。

在系統使用過程當中,也能夠經過 init 命令切換到不一樣的工做模式,以下:
init 3  (進入文本模式)
init 5  (進入圖形模式)
init 6  (從新啓動系統)
init 0  (關閉系統)

#
# inittab       This file describes how the INIT process should set up
#               the system in a certain run-level.
#
# Author:       Miquel van Smoorenburg, <miquels@drinkel.nl.mugnet.org>
#               Modified for RHS Linux by Marc Ewing and Donnie Barnes
#

# Default runlevel. The runlevels used by RHS are:
#   0 - halt (Do NOT set initdefault to this)
#   1 - Single user mode
#   2 - Multiuser, without NFS (The same as 3, if you do not have networking)
#   3 - Full multiuser mode
#   4 - unused
#   5 - X11
#   6 - reboot (Do NOT set initdefault to this)
