There is a small issue with installing MySQL on Leopard. The preference pane to start/stop Mysql does not work. Don’t know why but it just doesn’t. It will start manually but you need to make a slight adjustment to one file called ‘mysql.server’ in the directory ‘/usr/local/mysql/support-files/’. On line 62 change:
The following has happened in Leopard. All the users that are used for running applications have a changed username. All the daemon users start with an underscore in Leopard. This means that the user ‘mysql’ which we remember in Tiger is currenty known as ‘_mysql’. You will see this user as the owner of ‘/usr/local/mysql/data’. So somehow everything gets installed with the correct user.
The error of the Preference pane has been logged as a bug on the MySQL bug site.
If anyone can explain why the usernames have changed I would like to know!
By the way the only difference in installing MySQL on Leopard is the configure statement to compile MySQL, the rest is still the same. The new ./configure statement for PowerPC and Intel based Macs is:
As you see the CFLAGS have gone, the new XCode tools do their auto detection a lot better I guess.
