The mysql root account seems to be messed up.

two questions, when logging in, typing mysql-u root-p correctly jumps to the password line, but you can"t type the password on the keyboard. You can"t log in with a password, but you can log in directly by typing mysql. Is this the wrong place? I have been searching the Internet for a long time, and some people say that I may have messed up root users. What should I do? QAQ

| root |          | vm\_238\_239\_centos |
| root |          | 127.0.0.1            |
| root |          | ::1                  |
|      |          | localhost            |
