Keystone is run through wsgi_mod so you only need to have apache running. When apache is active it will use the wsgi module to take keystone requests and server out tickets.

Comment "driver = keystone.token.persistence.backends.sql.Token" of the [token] section in the /etc/keystone/keystone.conf file

This is due to keystone is not getting started properly and therefore port 35357 is not in listening mode. This seems to be anomalous behavior of service keystone. I am mentioning steps which have worked on my system for havana installtion on Ubuntu 12.04 Kernel version 3.2.0-67-generic. After a day of headache around this issue. Try these steps, preferably in the same order.

1) Remove keystone package:-

  apt-get remove  keystone

2) Reboot your system

 reboot

3) After reboot again INSTALL KEYSTONE.

apt-get install keystone

4) Check status of keystone service

 service keystone status

It will show start/running

5) Now do the necessary changes you want to do in /etc/keystone/keystone.conf

after making changes in conf file DO NOT RESTART KEYSTONE SERVICE

Use stop and start command to make an effect of restart but don't restart.

service keystone stop

service keystone start

For further help, pasting a dump of my CLI :-

Setting up keystone (1:2013.2.3-0ubuntu1~cloud0) ...
keystone start/running, process 1490
root@controller:~# vim /etc/keystone/keystone.conf

Even re-installing failed. I'm running Ubuntu 14.02 server on a virtual box. I'm attaching a screenshot for your consideration.

My keystone.conf file has following entries:

admin_token = openstack [database] ... connection = mysql://keystone:openstack@controller/keystone [token] ... provider = keystone.token.providers.uuid.Provider driver = keystone.token.persistence.backends.sql.Token [revoke] ... driver = keystone.contrib.revoke.backends.sql.Revoke [DEFAULT] ... verbose = True

The DNS is also not a problem, as it is resolving the 'controller' ip address.

Akshay/anybody .. Please help me. I'm stuck on this for over a month now.
