[Bug 1945538] [NEW] Database permission configured properly but I have the Access deny
Public bug reported:

At this point **one controller** with **two compute** node.

*But there is a problem here:*
user@controller001:~$ mysql
ERROR 1698 (28000): Access denied for user 'user'@'localhost'
user@controller001:~$ sudo mysql
MariaDB [(none)]>
and:
user@controller001:~$ mysqladmin -uroot ping
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost''
user@controller001:~$ sudo mysqladmin -uroot ping
mysqld is alive
*Any try to discover new host make the below error:*
user@controller001:~$ sudo su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
....
sqlalchemy.exc.OperationalError: (pymysql.err.OperationalError) (1045, "Access denied for user 'nova'@'controller001' (using password: YES)")
(Background on this error at: http://sqlalche.me/e/13/e3q8)
Expected result
===============
I am trying to add compute node to controller but it said to report this bug
Actual result
=============
user@controller001:~$ sudo su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
Found 2 cell mappings.
Skipping cell0 since it does not contain hosts.
Getting computes from cell 'cell1': 7466356a-3636-4698-af1c-fd64818ce722

In the below section improve database permission configured correctly
--------------------------------------------------------------------
*Databases are created properly:*
user@controller001:~$ sudo mysql
MariaDB [(none)]> SHOW DATABASES;
+--------------------+
| Database |
+--------------------+
| glance |
| information_schema |
| keystone |
| mysql |
| nova |
| nova_api |
| nova_cell0 |
| performance_schema |
| placement |
+--------------------+
*Grant all permissions for those databases:*
MariaDB [(none)]> SHOW GRANTS FOR nova;
+-----------------------------------------------------------------------------------------------------+
| Grants for nova@% |
+-----------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO `nova`@`%` IDENTIFIED BY PASSWORD '*3A4A03AC22526F6B591010973A741D59A71D728E' |
| GRANT ALL PRIVILEGES ON `nova`.* TO `nova`@`%` |
| GRANT ALL PRIVILEGES ON `nova_cell0`.* TO `nova`@`%` |
| GRANT ALL PRIVILEGES ON `nova_api`.* TO `nova`@`%` |
+-----------------------------------------------------------------------------------------------------+
*Have access to databases remotely from compute node:*
user@compute001:~$ mysql -unova -popenstack -h controller001
MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| nova |
| nova_api |

*But there is a problem here:*
user@controller001:~$ mysql
ERROR 1698 (28000): Access denied for user 'user'@'localhost'
user@controller001:~$ sudo mysql
MariaDB [(none)]>
and:
user@controller001:~$ mysqladmin -uroot ping
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost''
user@controller001:~$ sudo mysqladmin -uroot ping
mysqld is alive
*Any try to discover new host make the below error:*
user@controller001:~$ sudo su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
....
sqlalchemy.exc.OperationalError: (pymysql.err.OperationalError) (1045, "Access denied for user 'nova'@'controller001' (using password: YES)")
(Background on this error at: http://sqlalche.me/e/13/e3q8)
Expected result
===============
I am trying to add compute node to controller but it said to report this bug
Actual result
=============
user@controller001:~$ sudo su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
Found 2 cell mappings.
Skipping cell0 since it does not contain hosts.
Getting computes from cell 'cell1': 7466356a-3636-4698-af1c-fd64818ce722
