Remote connections are made through TCP/IP. That's why you get the sock error only for local connections. > will return following error message: > Can't connect to local MySQL server through socket > '/var/lib/mysql/mysql.sock' Somewhere over the rainbow - no, but in one of the my.cnf files on your local machine there is still a socket=/var/lib/mysql/mysql.sock entry. Another possible thing is the server is started by a script (mysqld_safe?) with the --socket=/var/lib/mysql/mysql.sock option. There are three my.cnf you should look for: 1) /etc/my.cnf = global options 2) <datadir>/my.cnf = server options, overriding global options 3) <home_directory>/.my.cnf = user specific options, overriding server options To make things a bit more complicated, you cannot only start the server with the socket option, but also the client (mysql). In the my.cnf's mentioned above, also check for [client] and [mysql] and see if socket=/var/lib/mysql/mysql.sock is specified anywhere.
