Why after changing bing-adress on ubuntu mysql server to 0.0.0.0 server works only from localhost?

Question

MySQL

Raised a server on ubuntu to install a java application.
The mysql server initially reads localhost ip, so you need to change bing-adress to 0.0.0.0 to take the port from the Internet, but after the change, it still continues to take localhost.
How to fix it?

Answer 1

1. Why hang MySQL on an external port at all? is the app on a different server? or somewhere in /etc/mysql(d). depending on the distribution
mysqld.cnf
bind-address = 0.0.0.0
2. don't forget to enable iptables or whatever firewall you have to have access from the server cluster with the Java application.
