The aim of this guide is to explain how to configure multi-tenant AMQP for multiple datacenters.

...

Note

To use multitenant AMQP, use a separate set of remote services for each cloud location (datacenter or public cloud region). Do not share any remote services

RabbitMQ multitenant properties

Property name

Description

Context

abiquo.rabbitmq.multitenant

To enable multitenant, set to true. By default it is disabled (false)

API

abiquo.rabbitmq.virtualHost

Logical separation where the configured Abiquo service manages AMQP entities. The default virtual host is /

API + RS

abiquo.rabbitmq.username

Username to connect to broker + virtualHost

API + RS

abiquo.rabbitmq.password

Password to connect to broker + virtualHost

API + RS

abiquo.datacenter.id

Unique datacenter ID. For a complete description see Abiquo configuration properties#datacenter

RS

...

API configuration

To configure the API.

  1. In the abiquo.properties file, set abiquo.rabbitmq.multitenant to true

  2. Create a virtual host for the API. The default virtual host is / and you can use this if you do not have a monolithic environment. (See below for monolithic configuration)

...

Code Block
rabbitmqctl add_user admin admin
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"

...

Watchtower configuration

The Watchtower server must use the same virtual host as the API, and it can also use the same user.

How to add a new data center

Each datacenter in Abiquo has a unique ID configured with the abiquo.datacenter.id property. Use the value of this property as the name of a new virtual host for the datacenter.

  1. Create a new virtual host named with the value of the abiquo.datacenter.id property value

    Code Block
    rabbitmqctl add_vhost dc2

  2. Add a new user for the new datacenter

    Code Block
     rabbitmqctl add_user dc2_user dc2_password

  3. Configure access to the new virtual host for the Abiquo API user

    Code Block
    rabbitmqctl set_permissions -p dc2 admin ".*" ".*" ".*"

  4. Configure access to the new virtual host for the datacenter user

    Code Block
     rabbitmqctl set_permissions -p dc2 dc2_user ".*" ".*" ".*"

...

Check permissions in the new datacenter

To list permissions on the virtual hosts use the following commands. Log in as the api user to access the API virtual host.

...

Code Block
> rabbitmqctl list_permissions -p dc2
Listing permissions in vhost "dc2" ...
dc2_user.*.*.*
admin.*.*.*

Check properties in the new datacenter

On the Remote services servers (including separate V2V servers), edit the abiquo.properties file and check that the properties on remote services match the configured values:.

Code Block
abiquo.datacenter.id = dc2
abiquo.rabbitmq.virtualHost = dc2
abiquo.rabbitmq.username = dc2_user
abiquo.rabbitmq.password= dc2_password
