ERROR 2003 (HY000): Can't connect to MySQL server on 'XXX.XX.XX.XX' (110)
I had setup another instance only for MySQL server.
This is overall what I did to setup my remote access for MySQL:
Configure
vi /etc/my.cnf
[mysqld]
bind-address=SQL-SERVER-IP
# skip-networking
/etc/init.d/mysql restart
Allow firewall ports
sudo ufw allow 3306/tcp
sudo ufw allow 3306
sudo ufw allow 8080/tcp
sudo ufw allow 8080
sudo service ufw restart
Grant access to remote IP address
mysql -u root -p mysql
GRANT ALL ON foo.* TO root@'SECOND-INSTANCE-SERVER-IP' IDENTIFIED BY 'PASSWORD';
Query OK, 0 rows affected, 1 warning (0.00 sec)
exit
Test it
mysql -u root -h 'SECOND-INSTANCE-SERVER-IP' -p
Error produced:
ERROR 2003 (HY000): Can’t connect to MySQL server on ‘SECOND-INSTANCE-SERVER-IP’ (110)
