Start the Identity service

In Kilo and newer releases, the Identity service should use the Apache HTTP Server with the mod_wsgi module instead of the eventlet library. Using the proper WSGI configuration, the Apache HTTP Server binds to ports 5000 and 35357 rather than the keystone process.

Important

Eventlet support will be removed in OpenStack Newton.
