Connect to mysql server without sudo

Question

The command:

mysql -u root -p

gives the error:

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


        

Answer 1

You need to change algorithm. Following work for me,

mysql > ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '';
mysql > FLUSH PRIVILEGES;

Answer 2

You can use the below query:

GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost' IDENTIFIED BY 'password';

This query is enough.

Answer 3

This answer needs to be slightly adapted for mariaDB instead of mysql.

First login as root using sudo:

$ sudo mysql -uroot

Then alter the mariadb root user:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password USING PASSWORD('mypassword');
FLUSH PRIVILEGES;

From now on sudo is not longer needed:

$ mysql -uroot -p

Version used: mysql Ver 15.1 Distrib 10.4.13-MariaDB, for osx10.15 (x86_64) using readline 5.1

Answer 4

The error Message:

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

means that the Server not allow the connect for this user and not that mysql cant access the socket.

try this to solve the problem:

Login in your DB

sudo mysql -u root -p

then make these modifications:

MariaDB []>use mysql;
MariaDB [mysql]>update user set plugin=' ' where User='root';
MariaDB [mysql]>flush privileges;
MariaDB [mysql]>exit

try login again without sudo

Answer 5

You can use the same ROOT user, or a NEW_USER and remove the SUDO privileges. Below example shows how to remove connect using ROOT, without SUDO.

Connect to MY-SQL using SUDO

sudo mysql -u root

Delete the current Root User from the User Table

DROP USER 'root'@'localhost';

Create a new ROOT user (You can create a different user if needed)

CREATE USER 'root'@'%' IDENTIFIED BY '';

Grant permissions to new User (ROOT)

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;

Flush privileges, so that the Grant tables get reloaded immediately. (Why do we need to flush privileges?)

FLUSH PRIVILEGES;

Now it's all good. Just in case, check whether a new root user is created.

SELECT User,Host FROM mysql.user;

+------------------+-----------+
| User             | Host      |
+------------------+-----------+
| root             | %         |
| debian-sys-maint | localhost |
| mysql.session    | localhost |
| mysql.sys        | localhost |
+------------------+-----------+
4 rows in set (0.00 sec)

Exit mysql. (Press CTRL + Z). Connect to MySQL without SUDO

mysql -u root

Hope this will help!

Answer 6

first login to your mysql with sudo.

then use this code to change "plugin" coloumn value from "unix_socket" or "auth_socket" to "mysql_native_password" for root user.

UPDATE mysql.user SET plugin = 'mysql_native_password' WHERE user = 'root' AND plugin IN ('unix_socket', 'auth_socket');

FLUSH PRIVILEGES;

finally restart mysql service. that's it.

UPDATE:

In new versions of mysql or mariadb you can use :

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password USING PASSWORD('your-password');
FLUSH PRIVILEGES;
