SQL error during alembic.migration when populating Neutron database on MariaDB 10.0

I am trying to install openstack using this guide http://docs.openstack.org/juno/install-guide/install/apt/content/neutron-controller-node.html (http://docs.openstack.org/juno/instal...)

while populating database using the command

su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \
--config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade juno" neutron

I get the following error NotImplementedError: No support for ALTER of constraints in SQLite dialect

There is a resolution here at this link https://bugs.launchpad.net/neutron/+bug/1384555 (https://bugs.launchpad.net/neutron/+b...)

However, I am finding it difficult to fix this. One of the persons in IRC suggested me to add run_as_root in my utils.execute. However, there are lot of places where utils.execute is present and I am not sure where I need to make that change. Has anyone faced similar issue?

Are you using Maria DB or are you using SQLite as the DB?

Can you paste your neutron.conf file , the section where you define the db connection.

Here is the problem:

connection = mysql://neutron:openstack@controller/neutron

connection = sqlite:////var/lib/neutron/neutron.sqlite

You have 2 connection defined!!! Comment out the sqlite connection and try again.

Hi I'm seeing the same issue. I am using only defined one connection in the neutron.conf file.

connection = mysql://neutron:cisco123@controller/neutron

Note: initialy I tried with the below one as per the openstack docuemntation. but either of this was not working. connection = mysql+pymysql://neutron:NEUTRON_DBPASS@controller/neutron

I get the following errors. what could be the issue? could you please help me here
