# Creating Moodle database
# ---

# These are the steps to create an empty Moodle database. Substitute your 
# own database name, user name and password as appropriate.
#
# The instructions assume that the web server and MySQL server are on the 
# same machine. In this case the 'dbhost' is 'localhost'. If they are on 
# different machines substitute the name of the web server for 'localhost' 
# in the following instructions and the 'dbhost' setting will be the name
# of the database server. Databases have a "Character set" and a "Collation".
# For Moodle, we recommend the Character Set be set to utf8mb4 and the 
# Collation utf8mb4_unicode_ci. You may get the option to set these values 
# when you create the database. If you are not given a choice, the default 
# options are probably good. An install on an old server may have the wrong 
# settings.


# db_name: moodle
# db_user: moodleuser
# db_pass: 3wSF.XTC+L9Z


# Command line

#    To create a database using the 'mysql' command line client, first log into MySQL

$ mysql -u root -p
Enter password: 

# (Enter the password you previously set - or been given - for the MySQL 'root' user). 
# After some pre-amble this should take you to the mysql> prompt.


#    Create a new database (called 'moodle' - substitute your own name if required).

# If you have successfully configured the recommended full UTF-8 support as described above run:

mysql> CREATE DATABASE moodle DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

# If you do not have the recommended full UTF-8 support run:

mysql> CREATE DATABASE moodle DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;


#    Add a user/password with the minimum needed permissions:

mysql> GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,CREATE TEMPORARY TABLES,DROP,INDEX,ALTER ON moodle.* TO moodleuser@localhost IDENTIFIED BY 'yourpassword';

# ...which creates a user called 'moodleuser' with a password 'yourpassword'. 
# Make sure you invent a strong password and resist the temptation to 'GRANT ALL'.


#    Exit from mysql:

mysql> quit
