Tibo Beijen has a new post today showing his method for fixing mysqldump on Zend Server CE running on an OS X platform. The default install throws a socket error when you try to dump a database using the command.

Inspecting the mysql configuration contained in /usr/local/zend/mysql/data/my.cnf confirmed that the section [client] showed the socket as returned by executing SHOW VARIABLES; from the mysql client: /usr/local/zend/mysql/tmp/mysql.sock Although it is possible to specify the socket by using mysqldump's --socket switch, that doesn't really seem a 'solution'.

As a real solution to the problem was to copy over the my.cnf file from the custom location Zend Server has it in to the default "/etc/my.cnf" with settings pointing to the correct MySQL socket.
