How remind password for mysql localhost base at Linux Mint? - mysql

Question

I have a little confusing problem. Trying to connect into own localhost sql database. But always got an error with 1045 code:
mysql.connector.errors.ProgrammingError: 1045 (28000):
Access denied for user 'root'#'localhost' (using password: NO)
Pycode:
config = {
'user': 'root', #Tried our username and empty
'password': '', #Tried few always used for learning, empty, and bruteforce with all isalnum letters from secound writed program with connector.Error catcher :P [to twelve string length].
'host': '127.0.0.1', #Tried localhost / Guazowy(from mysql status)
'database': 'outlet_refactor',
'raise_on_warnings': True, #Without this also.
}
serw = mysql.connector.connect(**config)
Also i tryied use other user, other host and passwords, maybe i once set password but forgot these. (I want to learn build database with python, but this problem for start is too enough for me. Over week i trying find solution)
Console send me that same error when try:
mysql -u root -p
Mine mysql serwer is started when i check with:
sudo service mysql status
Output:

Restart too isn't help
sudo service mysql stop
sudo service mysql start
Even i belive for dpkg to reconfigure/reset password (i tryied, but this is not for this).
I not have temporary generated password from 'MySQL Yum repository, MySQL SUSE repository, or RPM packages directly downloaded from Oracle', so
sudo grep 'temporary password' /var/log/mysql.log #File not exist
sudo grep 'temporary password' /var/log/mysql/error.log
doesn't print anythink, when I checking manually, just confirm grep results.
mysqladmin variables | grep socket #so grep port too isn't working
>>Out:
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'guaz'#'localhost' (using password: NO)'
Also i tryied few other methods in similar questions, but no one help with mine problem and now i can't find these. I'll be gratefull for help or any tips to solution :).

Answer 1

Try the followin command:
$ mysqladmin -u root password NEWPASSWORDHERE
As example:
$ mysqladmin -u root password 123456
to test if that is working:
$ mysql -u root -p'123456' -e 'show databases;'
To change your user password:
Conect from terminal to mysql with root:
$ mysql -u root -p
Go to table mysql:
mysql> use mysql;
Change user password:
mysql> update user set password=PASSWORD("123456") where User='guaz';
Flush privilegies:
mysql> flush privileges;
mysql> quit
