如下文 id:3:initdefault: 那一行,数字选项 3 表示系统启动时默认进入多用户文本模式,通过修改该数字,即可默认进入不同的模式。该数字选项值为 0~6 。
注意:
0 - 表示关闭系统(千万不要把默认设置成0哦!)
1 - 单用户模式
2 - 多用户模式,没有NFS服务
3 - 多用户文本模式
5 - 图形模式
6 - 系统重新启动
启动进入多用户文本模式后,可以使用命令 startx 进入图形模式。
在系统使用过程中,也可以通过 init 命令切换到不同的工作模式,如下:
init 3 (进入文本模式)
init 5 (进入图形模式)
init 6 (重新启动系统)
init 0 (关闭系统)

# 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)
