如果您考虑通过RabbitMQ实现更大规模的AMQP基础架构，那么肯定会尝试使用Ansible作为基础架构部署者，因为Ansible的RabbitMQ模块非常容易使用，让我们举个例子。
任务：
使用名称：ansible_exchange创建DIRECT交换，ansible_exchange绑定两个队列myRemoteQueue1 和myRemoteQueue2，路由键为key1和key2。
让我们为这个任务来创建用于基础设施的部署容易ansible角色：
../roles/create_infra/tasks/main.yml
# Create exchange on remote host
- rabbitmq_exchange:
name: ansible_exchange
type: direct
login_user: guest
login_password: guest
login_port: 15672
# Create a queues on remote host
- rabbitmq_queue:
name: "{{item}}"
login_user: guest
login_password: guest
login_host: localhost
login_port: 15672
with_items:
- myRemoteQueue1
- myRemoteQueue2
- rabbitmq_binding:
name: ansible_exchange
destination: myRemoteQueue1
type: queue
routing_key: key1
- rabbitmq_binding:
name: ansible_exchange
destination: myRemoteQueue2
type: queue
routing_key: key2
|
并使用简单的基本剧本启动此角色：
infra.yml：
- hosts：localhost
gather_facts：false
roles：
- create_infra
|
我相信create_infra的任务代码是selfexplanatory，有关更多信息，请参阅以下内容：
http://docs.ansible.com/ansible/latest/rabbitmq_exchange_module.html http://docs.ansible.com/ansible/latest/rabbitmq_binding_module.html http://docs.ansible.com/ansible/latest/rabbitmq_queue_module.html
|
现在让我们来启动infra.yml playbook：
$ ansible-playbook infra.yml
PLAY [localhost] <strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>*</strong><strong>**

并检查剧本是否符合我们的要求：
exchange创建验证：
$ ./rabbitmqctl list_exchanges | grep "ansible_"
ansible_exchange direct
|
队列创建验证：
$ ./rabbitmqctl list_queues | grep myRemoteQueue*
myRemoteQueue1 0
myRemoteQueue2 0
|
绑定创建验证：
$ ./rabbitmqctl list_bindings | grep ansible_
ansible_exchange exchange myRemoteQueue1 queue key1 []
ansible_exchange exchange myRemoteQueue2 queue key2 []
|
伙计们，使用Ansible的AMQP模块并享受乐趣！
