check /etc/init.d/zenoss...

# environment variables
export ZENHOME="/opt/zenoss"
export RUNUSER="zenoss"
export SNMPD_CONF="/etc/snmp/snmpd.conf"
export MY_CNF="/etc/my.cnf"
export ZOPE_USERNAME="admin"
export ZOPE_PASSWORD="zenoss"
export ZOPE_LISTEN_PORT="8080"

check /opt/zenoss/etc/zenbackup.conf

I definitely don't have zenoss run or connect to mysql as root but
created a mysql user named zenoss and this user has sufficient
privileges to do whatever it needs to do.
