When I log in to mariadb, I do not have access to a database named mysql.
I get the following error:
MariaDB [(none)]> use mysql
ERROR 1044 (42000): Access denied for user ''#'localhost' to database 'mysql'

In MySQL you can make logging appear in JSON format by installing component_log_sink_json component and enabling this component:
INSTALL COMPONENT 'file://component_log_sink_json';
SET PERSIST log_error_services = 'log_filter_internal; log_sink_json';
Source: https://dev.mysql.com/doc/refman/8.0/en/error-log-json.html
But this does not work in MariaDB:
MariaDB > INSTALL COMPONENT 'file://component_log_sink_json';
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'COMPONENT 'file://component_log_sink_json'' at line 1
MariaDB > SET log_error_services = 'log_filter_internal; log_sink_json';
ERROR 1193 (HY000): Unknown system variable 'log_error_services'
How can I make MariaDB log in JSON format?
I recently install MariaDB and use DB
but it has error on login
I check my plugin
root localhost mysql_native_password
Enter password:
ERROR 1698 (28000): Access denied for user 'root'#'localhost'
How can I fix??
Recent versions of MariaDB will authenticate users via unix_socket plugin when connecting via unix_socket (localhost).
So if you need to connect as root, just do a
$ sudo mysql
and enter password afterwards.
I install a laragon on my windows 10 and using the latest mariadb database
Ver 15.1 Distrib 10.2.12-MariaDB, for Win64 (AMD64)
but when I try to connect using this command
mysql -u root -p
I received this error
ERROR 2002 (HY000): Can't connect to MySQL server on 'localhost' (10061)
What is this error?
I don't know what to do.
When you install MariaDB, by default it creates a database called "mysql".
If you delete that database, that exact error will appears. The solution is either recover that database or reinstall mariadb. I spent one day figuring out why does that error appeared to me.
Conclusion: Don't delete "mysql" database from mariadb.
befor installing moodle on ubuntu 16.04 server i have installed MariaDB and create a privilage like this :
# mysql -u root -p
MariaDB [(none)]> CREATE DATABASE moodle;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON moodle.* TO 'Admin'#'localhost' IDENTIFIED BY 'root';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> \q
after that i can with commande line access to moodle database with user: "Admin" and password:"root".
but in the install.php page of moodle if i give the user and password i got this error :
what is the problem please?
A bug in Moodle means it cannot detect the latest version of MariaDB database server used on all Ecenica Web Hosting packages and Managed Cloud Servers.
You can do the following:
Edit your Moodle config.php
Change $CFG->dbtype from mysqli to
mariadb
Save and Restart the installation of Moodle
It is an old post but, for someone who hits this page:
From the error it looks like the DB type selected in the screen prior to this was "MySQLi" instead of "MariaDb".
I would like to read an external file into MariaDB using the CONNECT engine. However, when trying to read from the file, I get an error message:
MariaDB [test]> create table test ( name varchar(100), team varchar(100) ) engine=CONNECT table_type=CSV file_name='/tmp/data.csv' header=1 sep_char=',' quoted=0;
Query OK, 0 rows affected (0.24 sec)
MariaDB [test]> select * from test;
ERROR 1296 (HY000): Got error 174 'Open() error 13 on /tmp/data.csv: Permission denied' from CONNECT
Checking the filesystem permissions gives me:
divingt#grisu ~ $ ls -l /tmp/data.csv
-rw-rw-rw- 1 divingt divingt 1658 Dec 31 13:59 /tmp/data.csv
So everybody should be able to read and write from the file.
Also in MYSQL the permissions allow for everything:
MariaDB [test]> SHOW GRANTS;
+------------------------------------------------------------------------------------------------+
| Grants for root#localhost |
+------------------------------------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'#'localhost' IDENTIFIED VIA unix_socket WITH GRANT OPTION |
| GRANT PROXY ON ''#'%' TO 'root'#'localhost' WITH GRANT OPTION |
+------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)
I run a Linux Mint system.
Thanks a lot for any help.
It turns out that the reason was that apparmor prevented mysqld from reading from reading the file. Disabling it (or changing the permissions) solved the problem.
