ssh reverse mysql tunnel with a aliased host-CodePudding

I am trying to ssh into my server and then access the mysql on localhost for quick prototype development when testing on live.

Here is my connection in the server:

mysql -h db_master_www -u game -D db_www -p

I then setup my tunnel (sp is my ssh config name)

~ssh -N -L 3336:db_master_www:3306 sp

And on my local machine

hutber@hutber:~$ mysql -h db_master_www -u game -D db_www -p
ERROR 2005 (HY000): Unknown MySQL server host 'db_master_www' (-2)

So logically I'll need to use my host as the ip and not the alias?

CodePudding user response：

When you use an ssh tunnel to map the local port 3336 to the remote port 3306, you would connect to 3336 locally:

mysql -h 127.0.0.1 -P 3336 -u game -D db_www -p

Make sure to use 127.0.0.1, not "localhost" because to the MySQL client, these are not the same.
