Grant privileges on MariaDB

I'm trying to grant privileges for user on MariaDB 10, but I've got an error 1045

[root@lw343 ~]# mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
MariaDB [mysql]>

I have tried all what I found on the internet, but I've got the same error. I also tried creating new user, but I still got same error on every user I try to grant on.

Does anybody could help me to resolve this problem?

Thanks in advance.

First of all i would check if the database server is listening on the network.

netstat -tlpn | grep mysql

i expect something like this:

tcp        0      127.0.0.1:3306              0.0.0.0:*                   LISTEN

If the database server is listening on 127.0.0.1:3306, connection are allowed only from localhost. Change the following lines in 50-server.cnf and restart the database service (service mariadb restart).

bind-address = 0.0.0.0
  • Permit listening on multiple network interfaces or a specific IP address with bind-address

Your mysql.user tables shows that user root can connect only from localhost and 127.0.0.1.

If you need a remote user, that can connect to database from everywhere (@'%'), with root privileges, you can create another superuser. 

GRANT ALL PRIVILEGES ON *.* TO 'superuser'@'%' IDENTIFIED BY 'use_a_secure_password';

Now superuser has the same privileges as the default root account, beware!

As a final step following any updates to the user privileges:

FLUSH PRIVILEGES;

Also i notice that your mysql.user tables shows a user ruser that can connect over the network.

Ok, so first, understand that users are created as username/hostname combinations. So root@localhost is different from [email protected] So for a remote connection you cannot use root@localhost since that is for connecting from localhost

So, create a different user.

Secondly, if root@localhost already exists then don't use identified by since you already have a password....
