Step 1: Changing the root

View user's rights , whether it is mysql_native_password, if not, the auth_sock changed mysql_native_password.

update user set plugin = 'mysql_native_password' where user = 'root';

Or execute the following statement, so you do not need to perform content Step2 friends!

​
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

​

then

 flush privilege；

Exit mysql.

Step2 modify or set the root password

After exiting the use mysql -u root -p found not to log Mysql, reported the mistake to:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

After the second article reference has been resolved.

First log in with debian-sys-maint, password file in /etc/mysql/debian.cnf

mysql -u debian-sys-maint -p

Then modify the root password (password can be the same as before):

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

Then, quit; quit.

 

 

After these two steps can then use mysql -u root -p login Mysql, you do not need to bring sudo.
