I'm reading PHP & MySQL Novice to Ninja (5th edition).

I've installed MySQL in Mac OS X Lion (10.7.5) but when I go to the terminal (following instructions in Appendix A) and write:

"sudo /usr/local/mysql/bin/mysqld_safe", I get this message:

"WARNING: Improper use of the sudo command could lead to data loss
or the deletion of important system files. Please double-check your
typing when using sudo. Type "man sudo" for more information.

To proceed, enter your password, or type Ctrl-C to abort.


And I didn't continue.

The version of MySQL that I've downloaded is "Mac OS X ver. 10.6 (x86, 64-bit), DMG Archive" and my processor is 2.2 GHz Intel Core i7.

Previously I installed XAMPP and worked fine and then uninstalled it by moving it to the bin.
