[root@rdo ~(keystone_admin)]# openstack-db --service trove --init Please enter the password for the 'root' MySQL user: Failed to connect to the MySQL server. Please check your root user credentials.

I tried with admin password in keystonerc_admin but didn't work. If i type mysql, i got a mysql prompt and can see the dabases

Forget my request, i found the mysql password in the packstack answer file.

After these steps I followed the steps in http://docs.openstack.org/icehouse/install-guide/install/yum/content/trove-install.html to complete the setup of Trove (running Scientific Linux, thus using yum).
