Hello, Meher

Except checking the sites-enabled in Apache, because single-node installation is mainly for very limited feature development, multi-node installation is recommended: https://docs.openstack.org/developer/tricircle/installation-guide.html#multi-pod-installation-with-devstack

If you only have one node, you don't need to install the second node even if you follow the multi-node guide.

You can also talk to us directly through IRC channel #openstack-tricircle in freenode.

Best Regards

Hi Meher,

Welcome to join Tricircle!

Both Keystone and Tricircle services are running under Apache, so if Keystone failed to start after enabling Tricircle, I guess there might be some problems of Apache configuration. You can check what services are enabled in Apache by listing this folder: /etc/apache2/sites-enabled.

tricircle at zhiyuan-1:~/devstack$ ls /etc/apache2/sites-enabled/
keystone-wsgi-admin.conf  keystone-wsgi-public.conf  nova-placement-api.conf  tricircle-api.conf

Above is the result from my Ubuntu machine.

Also, could you provide me the log of DevStack after enabling Tricircle so I can get more hints.

Hello everyone,

I introduce myself; Meher Hihi; I am doing my internship at Orange Labs Networks Lannion-France for the diploma of computer network and telecommunications engineer.

I am working on innovative distribution solutions for the virtualization infrastructure of the network functions and more specifically on the Openstack Tricircle solution, which is why I join your community to participate in your discussions and learn from your advice.

Indeed, I try to install Tricircle on a single node by following this documentation “https://docs.openstack.org/developer/tricircle/installation-guide.html#single-pod-installation-with-devstack”.
I managed to install Devstack without any problems, but when I modify the local.conf file by adding the Tricircle plugin integration and the HOST_IP, the script does not want to work and stops on an error of Start of the Keystone service.

I wanted to know if the problem is with my config file that is attached or I lack other things to configure. You will also find in the file the IP address of the machine.

I thank you in advance for the help you will bring me. Sincerely,

Best regards,



Meher Hihi
