4 ways to modify MySQL root password (summary)

Method 1: Use the SET PASSWORD command

First log in to MySQL.

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

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

Method 2: Using mysqladmin

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

Example: mysqladmin -uroot -p123456 password 123

Method 3: Use UPDATE to edit the user table directly

First log in to MySQL.

mysql> use mysql; 
mysql> update user set password=password('123') where user='root' and host='localhost'; 
mysql> flush privileges;

Method 4: When you forget the root password, you can do this

Take Windows as an example:

1. Shut down the running MySQL service.
2. Open a DOS window and go to the mysql\bin directory.
3. Enter mysqld –skip-grant-tables and press Enter. –skip-grant-tables means skipping the permission table authentication when starting the MySQL service.
4. Open another DOS window (because the previous DOS window cannot be moved) and go to the mysql\bin directory.
5. Type mysql and press Enter. If successful, the MySQL prompt > will appear.
6. Connect to the privilege database: use mysql; .
6. Change the password: update user set password=password(“123”) where user=”root”; (don’t forget to add a semicolon at the end).
7. Refresh privileges (required step): flush privileges; .
8. Exit quit.
9. Log out of the system, log back in, and log in using the username root and the new password 123 you just set.
