CHAPTER 22 LEOPARD AS A WEB SERVER
Aside from the fact that SQLite is already set up for you, it has the major advantage of being
the same database server used throughout the system. Applications written with Core Data can
use SQLite as their backing store. That means you can share a database between your Core Data
application and your PHP web site without ever having to touch SQL.
NOTE For more information on Core Data and other application development topics, see
Chapter 24.
If you’re serving web pages from your machine, or if your remote host has SQLite (and the
requisite PHP modules) running, you’re good to go. Run sqlite3 from the command line
to access the included management program. You can also learn more by visiting http://
sqlite.org/.
MySQL
If, however, you want to be like everyone else and run MySQL, you’re going to have to install it
yourself. Fortunately, MySQL maintains a Mac OS X installer package on its web site,
www.mysql.org/. To install MySQL, simply download the disk image that matches your architecture
and run it.
NOTE At the time of this writing, there is no Leopard version of MySQL available on the
download site. This may change by the time you get there, but in either case, the 10.4 version
can be made to work with one minor tweak. See http://www.beyondmac.com/2007/10/30/
php-mysql-on-leopard-mysqlsock-location/.
NOTE Apple also provides a good tutorial on getting up to speed with MySQL, including
installation and initial configuration. See http://developer.apple.com/internet/opensource/
osdb.html.
Although it’s available in more traditional tarball format, I downloaded the more Mac-like
disk image installer package. This contains an installer for the database server itself, and a separate
installer if you’d like MySQL to start automatically. If you’re running a web server, that’s
probably a good idea.
Once it’s installed, you can start the MySQL server from the command line. It’s installed in
/usr/local, which is not in the default path, so to run any MySQL tools you will have to actually
go into the directory, or use the full path:
sudo -b /usr/local/mysql/bin/mysqld_safe
After entering your password, the server will start. The -b flag on sudo invokes the server as
a background process. At your option, you can eliminate the background flag on your first run
just to make sure everything is copacetic.
Alternately, if you installed the startup item, you can use it to start the MySQL database:
sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
Finally, the installer includes a MySQL preference pane for System Preferences, as shown in
Figure 22-7. Double-clicking will install it. The preference pane tells you whether MySQL is running,
lets you start and stop MySQL, and includes a setting to automatically start MySQL at
boot time.
