如何使用 HeidiSQL 通过 SSH 隧道连接到 MySQL unix 套接字？

Question

I'm properly establishing SSH tunnel and I can connect to MySQL users accesible via tcp connection but I don't know how to connect to users accesible only by unix socket. I know the correct socket location: /var/lib/mysql/mysql.sock and I can connect to it from the command line.

How do I connect via socket using HeidiSQL? Is this impossible when SSH tunnel is being used? When I enter '/var/lib/mysql/mysql.sock' into "Host/IP" then I get

Lost connection to MySQL server at 'handshake: reading initial communication packet', system error 22

UPDATE

My HeisiSQL connection settings:

Remotely, the command should be executed like: mysql -u mySqlUser -p mySqlPw -h localhost .

ssh remote-user@remote "mysql -u mySqlUser -p mySqlPw -h localhost"

As from there, you should be able to do your stuff
