Contrail Devstack Multi Node

To install OpenContrail using Devstack on two or more machines run the following on all machines. Make sure git is installed. Then create a new user stack. Run the following commands as root user.

apt-get install -y git
groupadd stack
useradd -g stack -s /bin/bash -d /opt/stack -m stack
echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

switch to stack user and setup an ssh key

sudo su stack
mkdir ~/.ssh; chmod 700 ~/.ssh
echo "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCpOiz4MYur5xEyvVn++vPLtmUMNOZw6dVzbRihittU2YqbMya/7edK9FAzCkwJBJi4IB6t9dtls4Ts4Gk5kTZCFAIseeBmNmjqgOn15N1UWkPcv5K42WaCukb6Blji6zU7Z09B6VZrq+M3H3TZvl3CB6hDbTQZnMx0wpP5iTONmGW/OCK/M5nfRAJwKNldGBtHEJa7TjCXzLPBdDagqcOXL9Ss83TVs3rTLBDJNMpy/8drgHLwVHjG9N7+Ltyb8XXa3i9SwN2Rpsv9ugPbQpBv2q4qD3CoZj+Gs9ImbGd48hIQXSk/u4B9ddScKT6Hw13ohnIzPBUpDZsNJyfnA4Ch qasim@Hound.local" > ~/.ssh/authorized_keys

Next clone the devstack repo

git clone https://git.openstack.org/openstack-dev/devstack
cd devstack
git checkout stable/mitaka

Controller Node

Create a file named local.conf with the contents of this file. Change the IP and interface to your IP and primary interface.

vi local.conf

Then run

./stack.sh

./stack.sh will run into the below mentioned error

Workaroud:

edit the file "/usr/local/lib/python2.7/dist-packages/openstack/session.py" at line 29 replace "openstack.version" with "mitaka"

Run

./unstack.sh
./stack .sh

Compute Node

Create a file named local.conf with the contents of this file. Change the IP and interface to your controller and compute hosts accordingly.

vi local.conf

Then run

./stack.sh

./stack.sh will run into some error. Open local.conf and uncomment line 22 & 23.
