What is the setting of the sql_connection variable in nova.conf? Can you use
the regular mysql client to connect using the data in the connection string?
A connection string
mysql://user:password@server.domain/database
would become
mysql -h server.domain -u user -ppassword database
on the command line. If that fails, the reported error will indicate what you
should do next.

Hi All,
I want to use the existing engine created by Openstack to connect to
the MYSQL Database, however somehow I am not able to connect. .
The existing engine gets connected to SQLite database(which is the
default db) and not MYSQL.
I got the Openstack session and engine from :
from nova.openstack.common.db.sqlalchemy import session as db_session
get_session = db_session.get_session
session = get_session()
get_engine = db_session.get_engine
engine=get_engine()
This is inbuilt session info of Openstack :
{'autocommit': True, 'autoflush': True, 'transaction': None,
'hash_key': 1L, 'expire_on_commit': False, '_new': {}, 'bind':
Engine(sqlite:opt/stack/nova/nova/openstack/common/db/nova.sqlite),
'_deleted': {}, '_flushing': False, 'identity_map': {},
'_enable_transaction_accounting': True, '_identity_cls': , 'twophase': False,
'_Session__binds': {}, '_query_cls': }
Then Manully created session and engine and able to connect to db and query it
The Manualy created session info is:
{'autocommit': False, 'autoflush': True, 'transaction':
,
'hash_key': 1L, 'expire_on_commit': True, '_new': {}, 'bind':
Engine(mysql://username:passworsd@hostip/nova), '_deleted': {},
'_flushing': False, 'identity_map': {},
'_enable_transaction_accounting': True, '_identity_cls': , 'twophase': False,
'_Session__binds': {}, '_query_cls': }
Please let me know how to proceed further.Any help is appreciated.
Thanks,
Swapnil
