想法＃1：有没有办法修复 RHEL 6.2 安装？
在启动过程中，最近强制重启后，我的 Linux 机器（RHEL 6.2）在成功启动 virt-who 后立即挂起。我可以在文本模式下使用登录屏幕（Alt + F2/F3...）。
我很困惑——我如何才能知道启动顺序中的下一步是什么？这一步很可能就是导致它挂起的原因。
这是最后保存的几行/var/log/boot.log：

答案1
获取系统的初始化级别：
[root@rhel6 ~]# INIT_LEVEL=$(cat /etc/inittab |tail -n1|cut -d":" -f2)
[root@rhel6 ~]# echo $INIT_LEVEL
3
列出在此运行级别启动的服务（它们按启动顺序排列），在您的情况下获取 virt-who 之后的行：
[root@rhel6 ~]# find /etc/rc${INIT_LEVEL}.d/S*
/etc/rc3.d/S02lvm2-monitor
/etc/rc3.d/S08ip6tables
/etc/rc3.d/S08iptables
/etc/rc3.d/S10network
/etc/rc3.d/S11auditd

这可能是最近才出现的错误。我上周也遇到了同样的问题。
