LINUX設置默認啓動模式 inittab
2007-01-12 11:24:45| 分類: IT技術 | 標籤:網絡 |字號 訂閱網絡
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)
[lwg@RHEL4 ~]$ cat /etc/inittab
#
# 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)
#
id:3:initdefault:
# System initialization.
