Looks like your database connection setup is not correct, either in
nova.conf or with username and password on the databasea:
2017-07-19 02:14:14.901 24784 ERROR nova.api.openstack.extensions
OperationalError: (pymysql.err.OperationalError) (1045, u"Access denied
for user 'nova'@'controller' (using password: YES)")
If this is not the case, pleae followup with more information.

Title:
Instance is not able to launch
Status in OpenStack Compute (nova):
Invalid
Bug description:
I followed the procedure from https://docs.openstack.org/ocata
/install-guide-ubuntu/InstallGuide.pdf to build OpenStack environment.
But while launching instance I got the error as follows;
Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/
and attach the Nova API log if possible.
<class 'sqlalchemy.exc.OperationalError'> (HTTP 500) (Request-ID:
req-d6a9eec9-0570-4844-9434-d85d04c52883)
After getting this error, I made a new database for Nova but it is
using the old database and giving the same error.
This is the nova-api.log file:
