Reset MySQL root password using ALTER USER statement after install on Mac

Question

I\'m new to the whole Mac experience. I recently installed MySQL and it seems I have to reset the password after install. It won\'t let me do anything else.

Now I al

Answer 1

Mysql 5.7.24 get root first login

step 1: get password from log

 grep root@localhost /var/log/mysqld.log
    Output
        2019-01-17T09:58:34.459520Z 1 [Note] A temporary password is generated for root@localhost: wHkJHUxeR4)w

step 2: login with him to mysql

mysql -uroot -p'wHkJHUxeR4)w'

step 3: you put new root password

SET PASSWORD = PASSWORD('xxxxx');

you get ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

how fix it?

run this SET GLOBAL validate_password_policy=LOW;

Try Again SET PASSWORD = PASSWORD('xxxxx');

Answer 2

Run these:

$ cd /usr/local/mysql/bin
$ ./mysqladmin -u root password 'password'

Then run

./mysql -u root

It should log in. Now run FLUSH privileges;

Then exit the MySQL console and try logging in. If that doesn't work run these:

$ mysql -u root
mysql> USE mysql;
mysql> UPDATE user SET authentication_string=PASSWORD("XXXXXXX") WHERE User='root';
mysql> FLUSH PRIVILEGES;
mysql> quit

Change xxxxxx to ur new password. Then try logging in again.

Update. See this http://dev.mysql.com/doc/refman/5.7/en/resetting-permissions.html

It should solve your problem.

If you are on oracle try this

ALTER USER username IDENTIFIED BY password

Answer 3

ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';

Use this line...

Answer 4

UPDATE user SET authentication_string=PASSWORD("MyPassWord") WHERE User='root'; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '("MyPassWord") WHERE User='root'' at line 1

Resolved with

ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';

Answer 5

Maybe try that ?

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('XXX');

or

SET PASSWORD FOR 'root'@'%' = PASSWORD('XXX');

Depending on which access you use.

(and not sure you should change yourself field names...)

Answer 6

in 5.7 version. 'password' field has been deleted. 'authentication_string' replace it

use mysql;
update user set authentication_string=password('123456') where user='root';
flush privileges;
