I install keystone in CentOs6.0 and run keystone-all ok，but when I add a tenant with V2.0 API,some error occured:

oslo.db.sqlalchemy.exc_filters File "/usr/lib64/python2.6/site-packages/MySQLdb/__init__.py", line 81, in Connect

oslo.db.sqlalchemy.exc_filters return Connection(args, *kwargs)

oslo.db.sqlalchemy.exc_filters File "/usr/lib64/python2.6/site-packages/MySQLdb/connections.py", line 187, in __init__

oslo.db.sqlalchemy.exc_filters super(Connection, self).__init__(args, *kwargs2)

oslo.db.sqlalchemy.exc_filters TypeError: 'read_timeout' is an invalid keyword argument for this function

Can anybody help me? Thanks!
