本人刚开始学linux,不知怎么误操作了,造成系统无法正常关机。
我的版本是centos release 5.6(Final)
kernel 2.6.18-238.el5xen on an i686
以下是出现的一些故障现象。
开机登录后进入的是
-bash-3.2#
运行csh后切换到正常状态
运行halt/poweroff/init 0都关不了机,显示:
The system is going down for system halt NOW!
INIT:Sending processes the TERM signal
INIT:no more processes left in this runlevel
就不动了。
键盘可使用,但是输入的内容只在屏幕显示出来。
运行/sbin/shutdown now最后显示:
Telling INIT to go to single user mode.
INIT:Going single user
INIT:Sending grocesses the TERM signal
INIT:no more processes left in this runlevel
sh-3.2#
在此状态下运行csh后自动登录为root。
若运行exit
系统就重新启动回到登录画面。
登录后运行reboot,系统可正常重启。
在网上查了很多方法,说是inittab文件的问题,我也看不出来。
我的inittab文件内容如下:
#
# 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.

# UPS connected and working correctly.

# If power was restored before the shutdown kicked in, cancel it.

还请各位高手帮忙看看是什么问题。
再次先谢谢各位了。 |
