Mysql MariaDB is not working with remote connections - mysql

Question

I've been scratching my head for a day and probably read so many articles and on how can I allow my MariaDB to listen to remote connections. Unfortunately getting the below error.
Host 'xxx.xxx.xxx.xxx' is not allowed to connect to this MariaDB server.
I also read this StackOverflow question, anotherQuestion and successfully able to create the new user and grant all permission with following MySQL query.
CREATE USER 'ahsensaeed'#'%' IDENTIFIED BY 'my_password';
GRANT ALL PRIVILEGES ON *.* TO 'ahsensaeed'#'%' WITH GRANT OPTION;
And below is my ahsensaeed user grants.
MariaDB [mysql]> show grants for 'ahsensaeed'#'%';
+--------------------------------------------------------------------------------------------------------------------------------------+
| Grants for ahsensaeed#% |
+--------------------------------------------------------------------------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'ahsensaeed'#'%' IDENTIFIED BY PASSWORD '*F794ABE2A12665587C6B6D8B61E2F7E987711AFA' WITH GRANT OPTION |
+--------------------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)
In the end, I just flush the privileges and after that, I go to my MariaDB configuration file and edit it. Below is the path where my MariaDB conf file placed.
/etc/mysql/mariadb.conf.d/50-server.cnf
The following shows my MariaDB file block.
[mysqld]
#
# * Basic Settings
#
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = 0.0.0.0
.....
.....
and then I just restart the mysql service via /etc/init.d/mysql restart. I also open the 3306 port on my client for mysql.
When the above solution not works I also add the bind-address = 0.0.0.0 in /etc/mysql/conf.d/mysql.cnf file, but still it failed with error.
The following shows how I requesting for MariaDB database from my server.
-> mysql -uahsensaeed -p -h hostIp
and then I got the below error.
ERROR 1130 (HY000): Host 'hostIp' is not allowed to connect to this MariaDB server
Edit Added the host and user data.
MariaDB [(none)]> select User,Host from mysql.user;
+------------+-----------+
| User | Host |
+------------+-----------+
| ahsensaeed | % |
| root | localhost |
+------------+-----------+
2 rows in set (0.00 sec)
Any help would be appreciated.

This worked for me (I`m using Ubuntu 18.04 as virtual machine and Windows 10 with Vagrant):
sudo mysql -e "CREATE DATABASE {db_name};"
sudo mysql -e "CREATE USER {user_name}#localhost IDENTIFIED BY '{password}';"
sudo mysql -e "UPDATE mysql.user SET Host='%' WHERE User='{user_name}';"
sudo mysql -e "GRANT ALL PRIVILEGES ON {db_name}.* TO '{user_name}'#'%';"
sudo mysql -e "FLUSH PRIVILEGES;"
sudo systemctl restart apache2
sudo systemctl restart mariadb
After that, you should edit the file:
/etc/mysql/mariadb.conf.d/50-server.cnf
And set bind-address property to your hostIP address or just comment this line out.
Finally, run commands:
sudo systemctl restart apache2
sudo systemctl restart mariadb
I hope this will suit your needs
