I use the command below with -f [requests ssh to run in the background], and -N [to not execute a remote command] $> ssh username@example.com -L 3307:example.com:3306 -p 2222 -f -N the -L argument specifies that 3307 is the port to be used locally from example.com [the remote server] on its 3306 port [MySQL default port]. Then run the command below to connect to MySQL with port 3007. $> mysql --host=127.0.0.1 --port=3307 --protocol=TCP -u mysqluser -p Hope this helps.
