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

...

API configuration

To configure the API:

...

.

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

2. Create an API 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)

Create an Abiquo API user with full access to the configured virtual host. Replace admin and admin with values for your environment.

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

...

Watchtower configuration

The virtual host to use must be the same one configured and used by the API and the user can also be the same.

Watchtower uses the properties defined in the abiquo.properties file, so be sure to configure the properties:

• abiquo.rabbitmq.virtualHost

• abiquo.rabbitmq.username

• abiquo.rabbitmq.password

See Abiquo configuration properties#rabbitmqWatchtower server must use the same virtual host as the API, and it can also use the same user.

1. On the Watchtower server, edit the watchtower properties files at these locations

   Code Block
   /etc/abiquo/watchtower/emmett.properties /etc/abiquo/watchtower/delorean.properties

2. In each file, configure the following properties. For a datanode services cluster, enter the three IP addresses, separated by commas.

   Code Block
   abiquo.rabbitmq.username = {$RABBITMQ_USER} abiquo.rabbitmq.password = {$RABBITMQ_PASSWORD} abiquo.rabbitmq.addresses = {$DATANODE_IP_ADDRESS}:5672 abiquo.rabbitmq.virtualHost = /

3. Restart the abiquo-emmett and abiquo-delorean services

See Abiquo configuration properties and search for .rabbitmq..

How to add a new data center

Each datacenter in Abiquo has a unique ID configured with the abiquo.datacenter.id property and . Use the value of this property will be used 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 that properties on remote services match the configured values:

abiquo.datacenter.id = dc2

...

abiquo.rabbitmq.virtualHost = dc2

...

abiquo.rabbitmq.username = dc2_user

...

abiquo.rabbitmq.password= dc2_password
