Grant privileges on MariaDB - sql

Question

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.

Answer 1

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.
Usefull ressources:
Adding User Accounts
Server Command Options - bind-address

Ok, so first, understand that users are created as username/hostname combinations. So root#localhost is different from root#192.168.1.5 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....
