This article introduces seven different methods to change the password of mysql Data. For more information, see.

Method 1:

(Applicable to Resetting passwords of other users by administrators or users with global permissions)
Enter command line mode
Mysql-u root mysql
Mysql> UPDATE user SET pass = PASSWORD ("new password") WHERE user = 'name ';
Mysql> flush privileges;
Mysql> QUIT


Method 2:
(The application is the same as above, but the method is different)
Mysql-u root mysql
Mysql> set password for name = PASSWORD ('new password ');
Mysql> QUIT


(I am not commonly using the above two methods. If I am an administrator, I will use other tools such as phpmyadmin or MYSQL-front to manage user permissions, Which is intuitive and convenient)


Method 3
Phpmyadmin is the simplest. Modify the user table of the mysql database,
But don't forget to use the PASSWORD function.

Method 4

Use mysqladmin, which is a special case stated above.
Mysqladmin-u root-p password mypasswd
After entering this command, you need to enter the original root password, and then the root password will be changed to mypasswd.
Change the root in the command to your username, and you can change your password.
Of course, if your mysqladmin cannot connect to mysql server, or you cannot execute mysqladmin,
This method is invalid.
In addition, mysqladmin cannot clear the password.
The following methods are used at the mysql prompt and must have the root permission of mysql:

Method 5

Mysql> insert into mysql. user (Host, User, Password) VALUES ('%', 'Jeffrey ', PASSWORD ('biscuit '));
Mysql> FLUSH PRIVILEGES
Specifically, this is adding a user with the username jeffrey and password biscuit.
Be sure to use the PASSWORD function, and then use flush privileges.

Method 6

Similar to method Sany, but the REPLACE statement is used.
Mysql> replace into mysql. user (Host, User, Password)
VALUES (%, jeffrey, PASSWORD (iscuit ));
Mysql> FLUSH PRIVILEGES

Method 7
Use the set password statement,
Mysql> set password for jeffrey @ "%" = PASSWORD (iscuit );
You must also use the PASSWORD () function,
However, you do not need to use flush privileges.


Method 8

Use the GRANT... identified by statement
Mysql> grant usage on *. * TO jeffrey @ "%" identified by iscuit;
Here, the PASSWORD () function is unnecessary and does not need to be flush privileges.

There are many methods, but at last the command is executed here.
