This article is about how mysql sets login passwords. The editor thought it was very practical, so I shared it with you as a reference. Let's follow the editor and have a look.

Mysql sets the login password: 1, use the SET PASSWORD command, the code is [mysql > set password for username @ localhost = password ('new password')]; 2, use the mysqladmin command.

The method of setting login password by mysql:

Method 1: use the SET PASSWORD command

Log in to MySQL first.

Format: mysql > set password for username @ localhost = password ('new password')

Example: mysql > set password for root@localhost = password ('123')

Method 2: use mysqladmin

Format: mysqladmin-u username-p old password password new password

Example: mysqladmin-uroot-p123456 password 123

Method 3: edit the user table directly with UPDATE

Log in to MySQL first.

Mysql > use mysql

Mysql > update user set password=password ('123') where user='root' and host='localhost'

Mysql > flush privileges

Method 4: use the Grant statement mysql > grant all on *. * to 'root'@'localhost' IDENTIFIED BY' your password 'with grant option; mysql > flush privileges

Method 5: you can do this when you forget your root password or initialize your password

Take windows as an example:

1. Shut down the running MySQL service.

two。 Open the DOS window and change to the mysql\ bin directory.

3. Enter mysqld-- skip-grant-tables enter. Skip-grant-tables means to skip authorization table authentication when starting the MySQL service.

4. Open another DOS window (because the DOS window just now cannot be moved), and change to the mysql\ bin directory.

5. Enter mysql enter, and if successful, the MySQL prompt > will appear.

6. Connect permissions database: use mysql;.

6. Change the password: update user set password=password ("123") where user=" root "; (don't forget to add the semicolon at last).

7. Refresh permissions (required): flush privileges;.

8. Exit quit.

9. Log out of the system, enter again, and log in with the user name root and the new password 123 you just set.

6. After setting up, you can test whether it is successful or not. Click on the connection test to indicate that it is set up successfully.

Thank you for reading! This is the end of the method of setting login password for mysql. I hope the above content can help you to some extent, so that you can learn more knowledge. If you think the article is good, you can share it and let more people see it.
