我的linux出现一个奇怪的问题，无法登陆root！！！

UNIXwlc 2003-08-15 03:17:01
今天开机由于进不了X，等我setup xconfigurator搞好后，退到文本模式，发现竟然root不能登陆！

提示：

localhost login ：root
login incorrect //竟然密码输入提示都不出现

login：

我把/etc/passwd 和 /etc/shadow 中的root密码全清了，还是不行！

请教各位大虾，我可不想重装！！

root会不会被谁一不小心给禁用了？
我以前就碰到过一次

重光盘进入RESECURE模式，拷贝login到/bin/login
重新登陆试试，可能的话把/var/log/secure贴出来。

re wangguoqin1001(王国钦) :
我的经验，即使enable了shadow密码，直接删除/etc/passwd的密码字段用户的口令也会被清空啊。没遇到过无法登陆的情况。请问，什么情况下会导致无法登陆呢？谢谢！！

会不会是你的/etc/shadow和/etc/passwd在此之前就被修改过了呢？据我所知，如果enable了shadow密码，可不是简简单单删掉密码段就可以登陆的，有时甚至可能出现无法登陆的情况，就像你的情况。查查有关资料吧。

localhost login ：root
login incorrect //竟然密码输入提示都不出现
~~~~~~~~~`~~~~~~~~~~~~~~`这个本来就不出现的.


感觉有没有输错密码?

根本就不给机会让输入密码，说明在用户名的地方肯定有问题，是不是？
那么解决问题，就要抓住用户名这一关键人物了
不过我对linux不熟，不知道如何弄，
最好的话，还是覆盖安装一遍了，这样会好些，

我受不了你!!!你在X窗口下你已经登录了,你要先退出再登录,或者切换到另一个模拟终端登录

我在X登陆窗口输入root，它竟然提示“输入的用户名或密码错误，检查caps……”，根本不出现输入密码的对话框！
而且我查看了hosts.allow和hosts.denny ，里面没有限制。

这个问题真怪！！第一次遇见！！！！

我以前在一个学校里也遇到过,一个用户就是没办法登入.

你看看是不是在/etc/host.deny /etc/host.allow中有你的名字了

linux mysql root登录_解决linux下mysql-server在root账户下无需密码就能登陆的问题
似乎只要coding，这些代码就要跟我过不去似的今天在linux上安装了mysql-server，想不到竟然被一个及其简单的问题给难住了。是的，我竟然无法登陆！！！在论坛，百度，google上苦苦搜寻了半天，终于找到了问题所在。本质上还是自己数据库学习的不够扎实导致的问题。废话不多说，直接上问题和解决方法。问题描述在ubuntu中安装mysql已经极其方便，只需要使用一个指令就ok了：sudo a...

ubuntu linux切换用户到root
我的电脑是64位-4G内存的戴尔，安装了Ubuntu Linux11.10，但是在安装应用软件时遇到点问题，就是得切换到root用户，登陆完后，默认是是administrator,否则没有权限修改文件系统里的文件内容。但是我在装系统的时候只设置了一个用户，在用su命令切换时提示输入秘密，我明明没有设密码，空密码竟然不行，真是让人郁闷。 sudo passwd root 这个命令是给root用户
root用户登陆后，显示bash-4.4$ ??
【问题】 最近在看linux指令操作，所以装了虚拟机centos,但是今天root登陆后命令下的显示有点奇怪，搜了下发现是因为少东西了，大概是在用cp、rm的时候删多了。。。。 【解决】 没有按照标准用户名显示，是因为删除了root 下的 .bash_profile 和 .bashrc 文件所造成的，可以从其他用户下拷贝这两个文件到 /root 就可以了 #进入home文件夹下的其他...
