Running openstack-neat on centos 6.7

[loai spatin]

Hi Anaton,

i try to install and running Openstack-neat on centos 6.7.

At this time a few components of the Juno release have been recompiled for centos 6 and are available in the repositories:

• openstack-nova
• openstack-ceilometer

I can't install keystone and glance on centos 6.7 and i got error that openstck-keystone and openstack-glance packages are not available.
Can i complete running Openstack-neat on centos 6.7?

Also I got  error when i run ./vms-boot-28-slow.sh

ERROR (CommandError): You must provide an auth url via either --os-auth-url or env[OS_AUTH_URL] or specify an auth_system which defines a default url with --os-auth-system or env[OS_AUTH_SYSTEM]

when i run export OS_AUTH_URL=http://controller:5000/v2.0/ then run again ./vms-boot-28-slow.sh I got error

ERROR (RequestTimeout): Request to http://localhost:5000/v2.0/tokens timed out (HTTP 408)

how to solve those errors?

Best regards,
Loai Spatin

Hi Loai,

It might be the case that the new versions of the OpenStack services are not compatible with Neat anymore. Since I haven't worked on this project in a long time, it's hard for me to tell how to resolve the issues you mentioned. You may try to follow some earlier discussions on how other people made Neat work for them, for example https://groups.google.com/forum/#!topic/openstack-neat/ox0Mjuz1HNk 

You may also try to contact the guys who made it work recently, and they might be able to help you. If you find the cause of the problems and they are in the code of Neat, please feel free to send a pull request on github, and I'll be happy to merge it in! Or just post the solution here, which will be helpful to others.

Cheers,

Anton

Hi Anton,

Centos 6 don't support openstack. So I work currently on centos 7.

data collector and  local manger now run ok probably, but i have errors in global manager:

I have this error when i run ./vms-boot-28-slow.sh:

Do you know what does OS_AUTH_URL equal?

Hi Loai,

Please try to change the following occurrences of "novaclient.v2" to just "novaclient": https://github.com/beloglazov/openstack-neat/search?utf8=%E2%9C%93&q=%22novaclient.v2%22&type=Code

Let me know if that doesn't work.

Cheers,

Anton

Hi Anton,

when i make the changes and run global manager i get:

Sorry, I just realized that was just a warning, so you can revert the changes. The actual error is:

requests.exceptions.ConnectTimeout: HTTPConnectionPool(host='localhost', port=5000): Max retries exceeded with url: /v2.0/tokens (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x33b27d0>: Failed to establish a new connection: [Errno 111] Connection refused',))

The script is trying to reach the Nova API at localhost:5000, but it's not available. Are you sure the API service is running at that address?

Cheers,

Anton
