# install mysqld, the python wrappers for mysql and libxml2, start mysqld
# - mysql-server
# - mysql
# - php-mysql
# - MySQL-python
# Change the root passwd of mysql:
# mysqladmin -u root password new_password
# Create the new database libvir
# mysqladmin -p create libvir
# Create a database user 'veillard' and give him passord access
# change veillard and abcde with the right user name and passwd
# mysql -p
# password:
# mysql> GRANT ALL PRIVILEGES ON libvir TO veillard@localhost
# IDENTIFIED BY 'abcde' WITH GRANT OPTION;
# mysql> GRANT ALL PRIVILEGES ON libvir.* TO veillard@localhost
# IDENTIFIED BY 'abcde' WITH GRANT OPTION;
#
# As the user check the access:
# mysql -p libvir
# Enter password:
# Welcome to the MySQL monitor....
# mysql> use libvir
# Database changed
# mysql> quit
# Bye
#
# Then run the script in the doc subdir, it will create the symbols and
# word tables and populate them with informations extracted from
# the libvirt-api.xml API description, and make then accessible read-only
# by nobody@loaclhost the user expected to be Apache's one
#
# On the Apache configuration, make sure you have php support enabled
