Remote access solutions can not.
The reason: By default mysql For safety reasons, do not support remote login mysql, you need to set permissions to open a remote login mysql
After logging in mysql enter the following command:
grant all privileges on *.* to 'root' @'%' identified by 'root';
flush privileges;
The reason: there is no open port 3306
/sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT
/etc/rc.d/init.d/iptables save --- will be permanently saved to modify firewall
