Extra info for Learning MySQL
For a production server, we recommend that you check the integrity of packages that you download. A simple way to do this is to compare checksums generated by a digest algorithm such as MD5. A digest algorithm takes some data (for example, an RPM file) as input and calculates a 128-bit number, or checksum, from this data. With a good digest algorithm, it’s practically impossible to change the data without changing the checksum, so if the checksums of two files match, you can be certain that the files are identical.
We’ve tested the instructions in this book using both XP and Vista. While we wouldn’t recommend using either version for a production server, they’re quite appropriate for learning the material in this book. We assume you’re using either XP or Vista; you can set up a suitable environment on older versions of Windows such as 98 and Me, but the process is less straightforward. When we say “Windows” in this book, we mean XP or Vista. 5 (Leopard) due for release in the next few months. OS X has a nice graphical user interface over a Unix-like heart, which means it’s not hard to use software originally designed for Unix or Linux.
Each file or directory can have read, write, and execute permissions set for the user who owns it, the group associated with it, and every other user. Using the Command-Line Interface | 15 When the operating system is asked to allow access to a file or directory, it looks to see who the user is and what groups this user belongs to. It then checks the user and the group associated with that file or directory, and allows access only if the permission settings are appropriate. Your group on a Linux or Mac OS X system is typically the same as your username, so, for example, the username and group for the user adam would both be adam.
