linux下su命令报错 cannot set groups Operation not operation not permitted !
1,命令【su】
鉴定故障
(1)第一种可能是你的密码真的输入错误;
(2)尽管密码输入的对,也一直报这样的错误,查看 /etc/passwd 和/etc/shadow权限
命令【ls -l /etc/psswd 】【ls -l /etc/shadow】
使用chmod 命令将其改为 644的权限
2,命令【su】
无法设置 组:不允许的操作
查看/bin/su
正常情况是:
-rwxr-xr-x root root ~~~~~~~~
命令chmod u+s /bin/su
