When an FMS is installed as root on a Linux system with and embedded MySql DB. The upgrade from to 5.6.2 fails at the DB upgrade section stating that it cannot be run as root.
A workaround for this is:
edit the FGLHOME/mysql/my.cnf file, add the following after [mysqld]
This allows the DB upgrade to complete when running the foglight_db_upgrade script or the fms -d -Dfoglight.database.upgrade=true switch when starting the fms.
The root user limitation has been removed. 5.6.3 will be able to install as root
