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