Create a tunnel to port 3306 on the remote server. This is the standard port for MySQL. Example:
ssh -N -f -L 13306:localhost:3306 \ email@example.com
|-N||Do not execute a remote command. This is useful for just forwarding ports (protocol version 2 only).|
|-f||Send ssh into the background.|
|-L||In this example: forward the local port |
Make sure the MySQL user and the database are opened to TCP access:
UPDATE USER SET host='%' WHERE user='DBUSER'; UPDATE DB SET host='%' WHERE user='DBUSER';
Now you can connect to the MySQL service running on the server:
localmachine>$ mysql -h 127.0.0.1 -P 13306 -u DBUSER -pDBPASSWORD
-h localhost did not work for me.
Save time and write
-h 127.0.0.1 instead!
Note: This technique will only work if access for remote machines is enabled on the server:
# in file: /etc/mysql/my.cnf ## disable remote access: #bind-address = 127.0.0.1 # enable remote access: bind-address = 0.0.0.0 # Restart MySQL after changing this section - a reload is not enough: $ service mysql restart
Warning: Allowing network access for MySQL creates potential security risks. Turn the feature off whenever you can!
