ERROR 1698 (28000): Access denied for user 'root'@'localhost'

Question

I\'m setting up a new server and keep running into this problem.

When I try to login to the MySQL database with the root user, I get the error:

Answer 1

step 1. sudo mysql -u root -p

step 2. USE mysql;

step 3. ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'admin';

Here 'admin' is your new password, yo can change it.

step 4. exit

Thanks. You are done.

Answer 2

That worked for me:

mysql --user=root mysql
CREATE USER 'some_user'@'%' IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON *.* TO 'some_user'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;

Answer 3

I would suggest to remove the Mysql connection -

UPDATE-This is for Mysql version 5.5,if your version is different ,please change the first line accordingly

sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-core-5.5 mysql-client-core-5.5
sudo rm -rf /etc/mysql /var/lib/mysql
sudo apt-get autoremove
sudo apt-get autoclean

And Install Again But this time set a root password yourself. This will save a lot of effort.

sudo apt-get update
sudo apt-get install mysql-server

Answer 4

I was having this issue on an Debian 8 VM that I was interacting with through Putty on my Windows 10 desktop.

I tried the various suggestions on here but nothing quite worked and I am running MariaDB on the Debian host. In the end I found that I couldn't start the db server in safe mode but I didn't need to and the following commands actually worked for me i.e. allowing a newly created MySql user to log into the MySql/MariaDB server:

sudo service mysql restart
sudo mysql # logs in automatically into MariaDB
use mysql;
update user set plugin='' where user='your_user_name';
flush privileges;
exit;
sudo service mysql restart # restarts the mysql service

If the above doesn't quite work for you, follow the steps outlined in zetacu's post above (zetacu) then follow my steps.

Now you should be able to use a remote terminal client and securely log into mysql using the command:

mysql -u your_user_name -p

*type in the password when prompted

Answer 5

I also faced the same issue at the first time.

Now it is fixed:

First, you copy the /etc/mysql/mysql.conf.d/mysqld.cnf file and past in to /etc/mysql/my.cnf.

You can do it by command:

sudo cp /etc/mysql/mysql.conf.d/mysqld.cnf /etc/mysql/my.cnf

Now let's Rest the password:

Use the following commands in your terminal:

sudo service mysql stop 
sudo service mysql start
sudo mysql -u root

Now you are inside the mysql console.

Then let's write some queries to reset our root password

USE mysql
update mysql.user set authentication_string=password('newpass') where user='root' and Host ='localhost';
update user set plugin="mysql_native_password"; 
flush privileges;
quit

Now we can clean /etc/mysql/my.cng

Open the above file in your editor and remove the whole lines inside the file.

After that let's restart mysql:

sudo mysql service restart 

Now let's use mysql with newly created password:

sudo mysql -u root -p

Finally enter your newly created password.

Answer 6

After hours of struggle with no solution here, this worked for me then I found a youtube video where it says the password column is now called authentication_string . So I was able to change my password as follows: First get into mysql from terminal

sudo mysql

then inside mysql type whatever after mysql>

mysql> use mysql
mysql> update user set authentication_string=PASSWORD("mypass") where user='root';
mysql> flush privileges;
mysql> quit;

at this point you are out of mysql back to your normal terminal place. You need to restart mysql for this to take effect. for that type the following:

sudo service mysql restart
