CentOs root登录错误 如何解决？

You session only lasted less than 10 seconds. If you have not logged out yourself, this could mean that there is some installation problem or that you may out of diskspace. Try logging in with one of the failsafe session to see if you can fix this program.

普通用户能登录上不?
另外检查下/bin/bash是否存在

小猴妹

普通用户也登录不了啦！上午学习ACL，是否和这个操作有关系？

chenyx

不清楚,你对/bin/bash进行过操作?

确定没有！单用户模式进入系统能修复吗？


   

dooros

你进单用户看下有shell么

问题解决啦~上午的时候 我用unix2dos命令修改了/etc/passwd文件，导致了登录的错误问题！谢谢你咯

做实验,最好有备份,这样的话,出问题可以恢复过来

囧，原来是这个问题，那个文件不能乱改啊。
