The following commands describe how to configure the MySQL database
on your LON-CAPA server.

Note:
+The following instructions assume you are logged in as 'root'. +
+Entering the mysql shell
-Enter the mysql shell--- mysql -u root -p mysql +OR +mysql -u root mysql (depending on whether you have set a root password) ++ |
Creating the mysql 'www' user (after entering mysql shell)

-CREATE DATABASE loncapa;

-INSERT INTO user (Host, User, Password)

+The TEST command will check the installation software, +the perl libraries on your system, the MySQL database, and +will also automatically test the real-time operation of the +LON-CAPA Apache web server. +
