Hi! I have mysql server and jspMyAdmin. I set default port(3306), host = localhost, and user = root with empty password in jspmyadmin config and in my.cnf.
But after deploy jspMyAdmin write Oops! an exception occurred. The exception was: java.sql.SQLException: Communication failure during handshake. Is there a server running on localhost:3306? The exception class was : class java.sql.SQLException
how to fix it?

funny question:
which of the 3 following do you get when you run “netstat -plant |grep ‘3306’”:
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN ####/mysqld
tcp 0 127.0.0.1:3306 127.0.0.1:* LISTEN ####//mysqld
tcp 0 x.x.x.x:3306 x.x.x.x:* LISTEN ####//mysqld
The 3rd one is just an example. It would be your external IP address. If it’s the 3rd one, you will need to modify /etc/my.cnf or /etc/mysql/my.cnf and change the bind to 0.0.0.0 or 127.0.0.1 and restart mysql. If it’s the other 2, I would guess odd firewall configuration.
