cp /var/www/html/clustercontrol/bootstrap.php.default /var/www/html/clustercontrol/bootstrap.php
# set the DB_PASS and DB_PORT in the bootstrap.php file
# normally cmon and 3306

cp /var/www/html/cmonapi/config/bootstrap.php.default /var/www/html/cmonapi/config/bootstrap.php
# set the CMON_TOKEN in the boostrap.php file. get the old one from the database
mysql -uroot -p -e “select token from dcps.apis where id=1”

cp /var/www/html/cmonapi/config/database.php.default /var/www/html/cmonapi/config/database.php
