How to connect MySQL through Jump servers: When you don't have direct access to mysql-server, you use jump-server. From your machine, you connect(ssh) to jump-server and from there you connect to your mysql-server. This can be avoided by using ssh- tunneling. Suppose your        jump server is `jump-ip`        mysql server is `mysql-ip`        your machine is `machine-ip` Just open ssh client(Putty in windows or terminal in linux/ios). Type:     ssh -L [local-port]:[mysql-ip]:[mysql-port] [jump-server-user]@[jump-ip] After this, you can use your localhost and local-port to access mysql-server on the remote machine directly. Eg. Your Jdbc url to access mysql database, in that case, will be jdbc:mysql://localhost:[local-port]/[database-name]
