Elizine sent a very good link.

It was a my.cnf bad configuration combined with a firewall problem. I could finally solve it.

Thanks a lot to eveybody !

Please post the following section of your mysql config:

[mysqld]
...
skip-networking
...
bind-address = 
...

Also please post the output of the following mysql command:

SELECT User, Host FROM mysql.user WHERE Host <> 'localhost';

Which user are you trying to grant remote access? Also please post any error you get.

Hi, maybe is late ... but if you are running your mysql in mysql secure installation you have to :

• create a user with related privileges on schema/tables you want and set limit hosting access to the IP you are connecting from (this means that the user can access only from that IP)

• comment in the file /etc/mysql/mysql.conf/mysql.cnf (this is the configuration file used by mysql secure installation) the following line:

#bind-address=127.0.0.1

• restart mysql sudo service mysql restart

• add to your mysql server firewall the following rule:
  sudo ufw allow from IP_FROM_YOU_CONNECT to any port 3306

• test from your remote location with
  mysql -u *USER_CREATED_BEFORE *-h *MYSQL_SERVER_IP* -p

if everything is ok you will prompt for the user password and you will get to mysql shell

Tested on UBUNTU 16.04 and mySQL 5.7

I found that changing the bind-address in the /etc/mysql/mysql.cnf the bind-address is ignored. You can check with mySQL Workbench under System Variables (search for bind keyword)

I hope this helps.

MySQL firewall provide by Datasunrise work as an intermediary between users and database. That fitlers each incoming and outgoing traffic.
