I just went through the install guide myself by coppy-paste and I did not hit this problem. There are following commands that you are probably missing that sets the permissions: ``` MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \ IDENTIFIED BY 'NOVA_DBPASS'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \ IDENTIFIED BY 'NOVA_DBPASS'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' \ IDENTIFIED BY 'NOVA_DBPASS'; ``` The percent sign '%' is there to accept connection from any client address. Moreover you also need to remember to configure DB to listen on IP address of the controller node as specified in the SQL install guide [1]
[1] https://docs.openstack.org/install-guide/environment-sql-database- rdo.html ** Changed in: nova Status: New => Invalid -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1833650 Title: Populate nova databases failed with mysql access denied Status in OpenStack Compute (nova): Invalid Bug description: Description =========== Fresh Install CentOS Linux release 7.6.1810 (Core) I followed "Install and configure controller node for Red Hat Enterprise Linux and CentOS" up to Install Nova on Controller, I configured Nova.conf and ran the DB commands. The following are failed: su -s /bin/sh -c "nova-manage api_db sync" nova su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova su -s /bin/sh -c "nova-manage db sync" nova I have my fix: use "controller" instead of "localhost": GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'controller' \ IDENTIFIED BY 'NOVA_DBPASS'; Then I could run populate nova databases commands successfully. Steps to reproduce =============== 1. Install CentOS Linux release 7.6.1810 (Core) 2. Install Keystone 4. Install Glance 6. Install Nova 7. Run the DB sync commands in order from the Docs Failure at > su -s /bin/sh -c "nova-manage db sync" nova and so on.. Expected result =============== Nova database Populates without error Actual result ============= Nova database does not populate and error thrown Environment =========== rocky Installed:
