The Ultimate Guide to High Availability with MariaDB

impossible to set root user

So far I used xampp, but now I would like to use directly mariadb. I have a problem: how set root user, giving the necessary permissions. I guess that I have to modify the mysql database. But today this happened (with skip-tables-grant): 

MariaDB [mysql]> SHOW GRANTS FOR 'root'@localhost; 
+-------------------------------------------------------------------------------------------------------------+
| Grants for root@localhost                                                                                   |
+-------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO `root`@`localhost` IDENTIFIED BY PASSWORD 'mypsw' |
+-------------------------------------------------------------------------------------------------------------+
1 row in set (0.001 sec)

MariaDB [mysql]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.001 sec)

MariaDB [mysql]> exit
Bye

But despite it now root is still without permissions (after commenting skip-tables and restarting mariadb):

MariaDB [(none)]> use mysql
ERROR 1044 (42000): Access denied for user 'root'@'localhost' to database 'mysql'

Where I was wrong?

In 10.3, the mysql.user table can be updated directly with something like the following:

1) Start the server --skip-grant-tables.

2) Connect and run the following SQL:

UPDATE mysql.user SET Select_priv="Y",Insert_priv="Y", Delete_priv="Y", Create_priv="Y", Drop_priv="Y", Reload_priv="Y", Shutdown_priv="Y", Process_priv="Y", File_priv="Y", Grant_priv="Y", References_priv="Y", Index_priv="Y", Alter_priv="Y", Show_db_priv="Y", Super_priv="Y", Create_tmp_table_priv="Y", Lock_tables_priv="Y", Execute_priv="Y", Repl_slave_priv="Y", Repl_client_priv="Y", Create_view_priv="Y", Show_view_priv="Y", Create_routine_priv="Y", Alter_routine_priv="Y", Create_user_priv="Y", Event_priv="Y", Trigger_priv="Y", Create_tablespace_priv="Y", Delete_history_priv="Y" WHERE Host="localhost" AND User="root";

3) Run FLUSH PRIVILEGES

4) Exit, and start the server normally

The above will not work from MariaDB 10.4, which introduced the mysql.global_priv table.
