222 Chapter 9 Creating Your Web Database
(If this command doesn’t work, verify that the MySQL server is running and the mysql
command is somewhere in your path.)
You should then enter your password. If all goes well, you should see a response
something like this:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1 to server version: 5.1.25-rc-community MySQL
Community Server (GPL)
Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the buffer.
mysql>
On your own machine, if you don’t get a response similar to this, make sure that you
have run mysql_install_db if required, you have set the root password, and you’ve
typed it in correctly. If it isn’t your machine, make sure that you typed in the password
correctly.
You should now be at a MySQL command prompt, ready to create the database. If
you are using your own machine, follow the guidelines in the next section. If you are
using somebody else’s machine, these steps should already have been done for you.You
can jump ahead to the “Using the Right Database” section.You might want to read the
intervening sections for general background, but you cannot run the commands specified
there. (Or at least you shouldn’t be able to!)
Creating Databases and Users
The MySQL database system can support many different databases.You will generally
have one database per application. In the Book-o-Rama example, the database will be
called books.
Creating the database is the easiest part. At the MySQL command prompt, type
mysql> create database dbname;
You should substitute the name of the database you want to create for dbname.To begin
creating the Book-O-Rama example, create a database called books.
That’s it.You should see a response like this (the time to execute will likely be different):
Query OK, 1 row affected (0.0 sec)
This means everything has worked. If you don’t get this response, make sure that you
typed the semicolon at the end of the line. A semicolon tells MySQL that you are finished,
and it should actually execute the command.
