MySQL root password change

Question

I have been trying to reset my MySQL root password. I have run the mysqld_safe --skip-grant-tables, updated the root password, and checked the user table to make sure it is

Answer 1

In MySQL 5.7, the password is replaced with 'authentication_string'.

use

update user set authentication_string=password('myfavpassword') where user='root';

Answer 2

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

You can find Resetting the Root Password in the MySQL documentation.

Answer 3

I searched around as well and probably some answers do fit for some situations,

my situation is Mysql 5.7 on a Ubuntu 18.04.2 LTS system:

(get root privileges)

$ sudo bash

(set up password for root db user + implement security in steps)

# mysql_secure_installation

(give access to the root user via password in stead of socket)

(+ edit: apparently you need to set the password again?)

(don't set it to 'mySecretPassword'!!!)

# mysql -u root

mysql> USE mysql;
mysql> UPDATE user SET plugin='mysql_native_password' WHERE User='root';
mysql> set password for 'root'@'localhost' = PASSWORD('mySecretPassword'); 
mysql> FLUSH PRIVILEGES;
mysql> exit;

# service mysql restart

Many thanks to zetacu (and erich) for this excellent answer (after searching a couple of hours...)

Enjoy :-D

This method doesn't work anymore, see this question for future reference...

Answer 4

For the current latest mysql version (8.0.16), none of these answers worked for me.

After looking at several different answers and combining them together, this is what I ended up using that worked:

update user set authentication_string='test' where user='root';

Hope this helps.

Answer 5

This worked for me -

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

Answer 6

Found it! I forgot to hash the password when I changed it. I used this query to solve my problem:

update user set password=PASSWORD('NEW PASSWORD') where user='root';

I forgot the PASSWORD('NEW PASSWORD') and just put in the new password in plain text
