How to do it...

First you need to download and configure the below services for the configuration node:

Apache ZooKeeper, an open source server for a highly reliable distributed coordination: https://zookeeper.apache.org/
Apache Cassandra, a distributed open source NoSQL database management system: http://cassandra.apache.org/
RabbitMQ message broker: https://www.rabbitmq.com/
network time protocol (NTP) for time synchronization: http://www.ntp.org/

The following script (12_5_open_contrail_configuration_node.sh) configures a server as the configuration node:

#!/bin/bash

# Download and manually install python-support, as it is dropped from Ubuntu 16.04. 
wget http://launchpadlibrarian.net/109052632/python-support_1.0.15_all.deb 
sudo dpkg -i python-support_1.0.15_all.deb 
 
# Configuring the package list. 
echo "deb http://ppa.launchpad.net/opencontrail/ppa/ubuntu precise main" | sudo tee -a /etc/apt/sources.list.d/opencontrail.list 
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 16BD83506839FE77 
echo "deb http://debian.datastax.com/community stable main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list 
curl -L http://debian.datastax.com/debian/repo_key | sudo apt-key add - 
 
# Run update 
sudo apt-get update 
 
# Install dependencies 
sudo apt-get install cassandra=1.2.18 zookeeperd rabbitmq-server ifmap-server 
 
# Install Contrail Config 
sudo apt-get install contrail-config 
 
# Configre ifmap-server 
echo "control:control" | sudo tee -a /etc/ifmap-server/basicauthusers.properties 
sudo service ifmap-server restart

Execute the script on a server to configure it as the configuration node:

$ sh 12_5_open_contrail_configuration_node.sh

The updates may leave you with the warnings similar to the following ones:

W: https://archive.cloudera.com/cm5/ubuntu/trusty/amd64/cm/dists/trusty-cm5.9.0/InRelease: Signature by key F36A89E33CC1BD0F71079007327574EE02A818DD uses weak digest algorithm (SHA1)
W: http://repo.saltstack.com/apt/ubuntu/14.04/amd64/archive/2015.8.11/dists/trusty/InRelease: Signature by key 754A1A7AE731F165D5E6D4BD0E08A149DE57BFBE uses weak digest algorithm (SHA1)

This is because of the weak digest algorithm used by the Cloudera and SaltStack repositories.

Now we will configure the analytics node with the following script (12_5_open_contrail_analytics_node.sh):

#!/bin/bash

# Get the redis server binary from http://ftp.ksu.edu.tw/FTP/Linux/ubuntu/ubuntu/pool/universe/r/redis/ 
# You may use any other working mirror as well. 
wget http://ftp.ksu.edu.tw/FTP/Linux/ubuntu/ubuntu/pool/universe/r/redis/redis-server_2.6.13-1_amd64.deb 
sudo apt-get install libjemalloc1 
 
# Install redis server 
sudo dpkg -i redis-server_2.6.13-1_amd64.deb 
 
echo "deb http://ppa.launchpad.net/opencontrail/ppa/ubuntu precise main" | sudo tee -a /etc/apt/sources.list.d/opencontrail.list 
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 16BD83506839FE77 
sudo apt-get update 
 
# Install Contrail Analytics 
sudo apt-get install contrail-analytics

You may execute the following script to configure a node as the analytics node:

$ sh 12_5_open_contrail_analytics_node.sh

Update the port in /etc/redis/redis.conf from 6379 to 6381 and restart the Redis server:

$ sudo service redis-server restart

Update discovery and Redis settings in /etc/contrail/contrail-collector.conf with that from etc/contrail/contrail-collector.conf in the accompanying source:

    [DISCOVERY]
    port=5998
    server=127.0.0.1
    
    [REDIS]
    port=6381
    server=127.0.0.1

Restart the collector.

$ sudo service contrail-collector restart

Update discovery and Redis settings in /etc/contrail/contrail-query-engine.conf shown as follows:

    [DISCOVERY]
    port=5998
    server=127.0.0.1
    
    [REDIS]
    port=6381
    server=127.0.0.1

Restart the query engine:

$ sudo service contrail-query-engine restart

Update Redis settings in /etc/contrail/contrail-analytics-api.conf:

    [REDIS] 
    server=127.0.0.1 
    redis_server_port=6381 
    redis_query_port=6381

Restart the analytics API server:

$ sudo service contrail-analytics-api restart

Finally, you may configure the compute node by using the script (12_5_open_contrail_compute_node.sh):

#!/bin/bash

# Configue the Ubuntu repositories. 
echo "deb http://ppa.launchpad.net/opencontrail/ppa/ubuntu precise main" | sudo tee -a /etc/apt/sources.list.d/opencontrail.list 
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 16BD83506839FE77 
sudo apt-get update 
 
# Install Contrail Virtual Rouer Agent 
sudo apt-get install contrail-vrouter-agent 
 
sudo modprobe vrouter 
echo "vrouter" | sudo tee -a /etc/modules

You may run it as follows:

$ sh 12_5_open_contrail_compute_node.sh

Update /etc/contrail/contrail-vrouter-agent.conf:

# IP address of discovery server 
server=10.8.1.10 
 
[VIRTUAL-HOST-INTERFACE] 
# Everything in this section is mandatory 
 
# name of virtual host interface 
name=vhost0 
 
# IP address and prefix in ip/prefix_len format 
ip=10.8.1.11/24 
 
# Gateway IP address for virtual host 
gateway=10.8.1.254 
 
# Physical interface name to which virtual host interface maps to 
physical_interface=eth1

Update /etc/network/interfaces:

auto eth1 
iface eth1 inet static 
        address 0.0.0.0 
        up ifconfig $IFACE up 
        down ifconfig $IFACE down 
 
auto vhost0 
iface vhost0 inet static 
        pre-up vif --create vhost0 --mac $(cat /sys/class/net/eth1/address) 
        pre-up vif --add vhost0 --mac $(cat /sys/class/net/eth1/address) --vrf 0
        --mode x --type vhost 
        pre-up vif --add eth1 --mac $(cat /sys/class/net/eth1/address) --vrf 0
        --mode x --type physical 
        address 10.8.1.11 
        netmask 255.255.255.0 
        #network 10.8.1.0 
        #broadcast 10.8.1.255 
        #gateway 10.8.1.254 
        # dns-* options are implemented by the resolvconf package, if installed 
        dns-nameservers 8.8.8.8

Restart the networking and vRouter agents, and finally restart the compute node:

$ sudo service networking restart
$ sudo service contrail-vrouter-agent restart
$ sudo reboot now
