Change mysql user password using command line

Question

I\'m trying to update the password for a database user using the command line, and it\'s not working for me. This is the code I\'m using:

mysql> UPDATE user S         


        

Answer 1

In your code, try enclosing password inside single quote. Alternatively, as per the documentation of mysql, following should work -

SET PASSWORD FOR 'jeffrey'@'localhost' = PASSWORD('cleartext password');

FLUSH PRIVILEGES;

The last line is important or else your password change won't take effect unfortunately.

EDIT:

I ran a test in my local and it worked -

mysql>  set password for 'test' = PASSWORD('$w0rdf1sh');
Query OK, 0 rows affected (0.00 sec)

Mine is version 5. You can use following command to determine your version -

SHOW VARIABLES LIKE "%version%";

Answer 2

Your login root should be /usr/local/directadmin/conf/mysql.conf. Then try following

UPDATE mysql.user SET password=PASSWORD('$w0rdf1sh') WHERE user='tate256' AND Host='10.10.2.30';
FLUSH PRIVILEGES;

Host is your mysql host.

Answer 3

As of MySQL 5.7.6, use ALTER USER

Example:

ALTER USER 'username' IDENTIFIED BY 'password';

Because:

• SET PASSWORD ... = PASSWORD('auth_string') syntax is deprecated as of MySQL 5.7.6 and will be removed in a future MySQL release.

• SET PASSWORD ... = 'auth_string' syntax is not deprecated, but ALTER USER is now the preferred statement for assigning passwords.
