Change nova_cell0 from previous installation

I change the management interface, so i change some steps in openstack deployment in the configuration of nova_cell0, i found some error with this command

/bin/sh -c "nova-manage db sync" nova:

ERROR: Could not access cell0. Has the nova_api database been created? Has the nova_cell0 database been created? Has "nova-manage api_db sync" been run? Has "nova-manage cell_v2 map_cell0" been run? Is [api_database]/connection set in nova.conf? Is the cell0 database connection URL correct? Error: (pymysql.err.OperationalError) (1045, u"Access denied for user 'nova'@'x.x.x.x' (using password: YES)") (Background on this error at: http://sqlalche.me/e/e3q8)

'nova'@'x.x.x.x' use the previous management interface . How can change this?
