I ran, on one console:

erelsgl@ubuntu:~$ mysql-proxy –proxy-backend-addresses=$MYSQL –log-level=debug2011-11-22 09:43:30: (message) mysql-proxy 0.8.2 started
2011-11-22 09:43:30: (debug) max open file-descriptors = 1024
2011-11-22 09:43:30: (message) proxy listening on port :4040
2011-11-22 09:43:30: (message) added read/write backend: qa-srv:3308

And on another console:

erelsgl@ubuntu:~$ mysql –user root –host=localhost –port=4040
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 81
Server version: 5.1.41-3ubuntu12.10 (Ubuntu)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> show databases;

However, instead of seeing the databases on the remote server (qa-srv) I saw the databases on my local server!

I also tried this:

erelsgl@ubuntu:~$ mysql –user root –host=qa-srv –port=4040
ERROR 2003 (HY000): Can't connect to MySQL server on 'qa-srv' (111)

I also tried running the proxy instead of the mysql daemon:

erelsgl@ubuntu:~$ sudo service mysql stop
mysql stop/waiting
erelsgl@ubuntu:~$ mysql-proxy –proxy-backend-addresses=$MYSQL –log-level=debug –proxy-address=0.0.0.0:3306

2011-11-22 14:14:25: (message) added read/write backend: qa-srv:3308

And on another console:

erelsgl@ubuntu:~$ mysql –user root
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

How can I tell my mysql client to connect to the remote server via the local proxy?
