作为一个Linux系统管理员,你可能会把Linux 超级用户密码遗忘了,把/etc/inittab或/etc/rc.d/rc.sysinit之类文件误编辑,导致系统不能正常启动的恼人错误?
而为了解决以上问题,你就需要进到linux根文件系统处于可读写状态的单用户模式下。
下面介绍在GRUB引导下进入Linux单用户模式的三种方式:
1.硬件环境:
intel P4 / 1G RAM / sata 80G
2.软件环境:
(1)Fedora Core 3(以下简称为FC3)和Windows2000 advance server双系统
(2)LVM管理Linux分区
(3)/boot/grub/grub.conf文件内容:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,2)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
#boot=/dev/sda
