Problem with connect MySQL and jspMyAdmin

  • Posted October 22, 2014

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.
