MySQL create database example - How to create a MySQL database and user account for Drupal alvin November 17, 2011 - 11:40am

MySQL “create database” FAQ: Can you share an example of how to create a MySQL database, including (a) creating the MySQL database and (b) a new MySQL database user, with all appropriate MySQL grant permissions for that user?

Sure. I've written about the process of How to add/create a MySQL user before, but I just ran across the Drupal installation documentation, which also has a nice description for how to create a MySQL database (for use with Drupal), so I thought I'd include some of their documentation here, along with some notes from my own recent Drupal and MySQL installation.

1) Create a new MySQL database

The first part of the Drupal installation document refers to creating a MySQL database:

Mac startup/login programs (startup items)

Mac startup/login programs FAQ: How do I set up a Mac program to automatically startup when I log in?

If you have a normal Mac application that you want to setup as a Mac startup program (also called a Mac "startup item"), the process is fairly simple, and I'll demonstrate the approach in this article.

The Linux `chmod` command

Linux file permissions FAQ: Can you share some examples of the Unix/Linux chmod command? (Also written as, "How do I change permissions on Unix files and directories?")

The chmod command name stands for "change mode", and as that name implies, the chmod command is used to change the mode of Unix/Linux files.

I'll start with some simple examples, then add some more details as we go along.

CakePHP Auth login - User login information

CakePHP Auth user login FAQ: Help, how do I get access to the CakePHP user object (user information) after using the CakePHP Auth component for the recommended CakePHP user login process?

A CakePHP user registration form example

CakePHP user registration FAQ: The cookbook covers the topic of CakePHP user login forms, but the CakePHP Auth module uses SHA1 for passwords, and the cookbook doesn't cover user registration (creating users, and SHA1 passwords); how do I set up a CakePHP user registration form, including all necessary CakePHP model, view, and controller classes?

Setting up a basic CakePHP registration form isn't too hard, er, well, once you know how to do it. Here's how.

A Use Case example of yesterday's User Story

In my Use Case quality article yesterday I wrote about a "User Story" for a fictional "User Logs In" requirement. To complete that article, I promised to write a Use Case version of that same user story. Here then is that sample "User Logs In" Use Case, which you can compare to yesterday's User Story.
