Trying to get OpenStack installed on Centos7, and I am following the installation instructions for Keystone located here:

https://docs.openstack.org/keystone/queens/install/keystone-install-rdo.html (https://docs.openstack.org/keystone/q...)

All of the commands seem to complete successfully and the database is created. Once I have done all of the exports at the bottom of the page and go to the next page:

https://docs.openstack.org/keystone/queens/install/keystone-users-rdo.html (https://docs.openstack.org/keystone/q...)

all of the commands fail. In the keystone.log, I get:

2018-04-18 15:00:59.292 2637 INFO keystone.common.wsgi [req-4450fa82-e7fd-4bbc-9cb3-9f938c5ad64c - - - - -] POST http://osctrl001.local.domain:35357/v3/auth/tokens (http://osctrl001.local.domain:35357/v...) 2018-04-18 15:00:59.311 2637 WARNING oslo_db.sqlalchemy.engines [req-4450fa82-e7fd-4bbc-9cb3-9f938c5ad64c - - - - -] SQL connection failed. 10 attempts left.: DBConnectionError: (pymysql.err.OperationalError) (2003, "Can't connect to MySQL server on 'osctrl001.local.domain' ([Errno 13] Permission denied)") (Background on this error at: http://sqlalche.me/e/e3q8)

/etc/keystone/keystone.conf has the following entry:

connection = mysql+pymysql://keystone:password@osctrl001.local.domain/keystone

I can connect and read the database using the mysql command line and copying and pasting the username and password from the connection string, and it works.
