Uninstall and reinstall mysql, simple and crude, quick results

Mysql version: 5.1
1. First check whether the mysql service is started. If it is started, stop it first. You can run it in the start menu and use the command:
net stop mysql
Open the first cmd window, switch to the bin directory of mysql, and run the command:
mysqld --defaults-file="C:Program FilesMySQLMySQL Server 5.1my.ini" --console --skip-grant-tables
Note:
This command opens the mysql service by skipping the permission security check, so that you do not need to enter the user password when connecting to mysql.
2. Open the second cmd window and connect to mysql:
Enter the command:
mysql -uroot -p
Appears:
Enter password:
Just press Enter here without entering a password.
Then a successful login message will appear,
Use command:
show databases;
Use the command to switch to the mysql database:
use mysql;
Change root password using command:
UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
Refresh permissions:
FLUSH PRIVILEGES;
Then log out and log in again:
quit
Login again:
mysql -uroot -p
A password prompt appears. Enter the new password to log in:
Enter password: ***
Display login information: Success, everything is ok

Modify the MySQL configuration file (default is /etc/my.cnf) and add a line skip-grant-tables under [mysqld]
Save the configuration file and restart the mysql service
Enter the MySQL command line again mysql -uroot -p, enter the password and press Enter directly, and you will enter the MySQL database
You can change the root password at this time:
mysql>use mysql;
mysql> update user set password=passworD("test") where user='root';
mysql> flush privileges;
mysql> exit;

The 2nd and 3rd floors are all correct. The 3rd floor is our common method. It is simple and crude and has quick results. 666

The mysqladmin command seems to work, I have done it before and forgot about it

It is possible to use the mysql command. I have done it before, but I have forgotten it now. You can go to Baidu, it’s available on Baidu!

Solution

Do you have navicat? If yes, open it. It seems that there is a user table in the mysql library, which contains users. If there is no navicat, try to log in as a super administrator
