# zmsetup
#
# Description:
# This is a setup wizard for the Mageia installation of ZoneMinder.
# It assumes a default installation using mysql (mariadb) and apache.
# It will check for and if necessary install mysql, start mysql, set up a
# mysql root password and create the ZoneMinder database if
# required, or update an existing one, setting required db permissions.
# It will check the password strength of any passwords created.
# It will set the date.timezone information in php.ini which is required for
# ZoneMinder to run.
# When all is ready it will start Mysql, Apache, and ZoneMinder and if all is
# well it will give the url of the running ZoneMinder server.
#
# Use:-
# After installation of ZoneMinder run this script as root and answer any questions.
# $ su
# # zmsetup
#===================================
#Changelog
# 25/08/2016 Force use of mysql root password
# Force change of zmuser password in zm.conf if still default
