Starting MySQL after upgrading to OS X Leopard
If you upgraded to OS X Leopard and are running MySQL from the MySQL.com installer1, you might be having some problems with starting it from the GUI interface. There isn’t a fix from MySQL yet, so to get around that… you can run it from the command-line.
Start MySQL from the command line
cd /usr/local/mysql; ./bin/mysqld_safe &
This should get MySQL up and running for you. If someone wants to share a tip on how to get this to start automatically on reboot, please post a comment and I’ll help get the word out.
