RabbitMQ is a complete and highly reliable enterprise messaging system based on the emerging AMQP standard.
RabbitMQ as AMQP broker with admin user and vhosts:
rabbitmq:
server:
enabled: true
memory:
vm_high_watermark: 0.4
bind:
address: 0.0.0.0
port: 5672
secret_key: rabbit_master_cookie
admin:
name: adminuser
password: pwd
plugins:
- amqp_client
- rabbitmq_management
host:
'/monitor':
enabled: true
user: 'monitor'
password: 'password'RabbitMQ as a Stomp broker:
rabbitmq:
server:
enabled: true
secret_key: rabbit_master_cookie
bind:
address: 0.0.0.0
port: 5672
host:
'/monitor':
enabled: true
user: 'monitor'
password: 'password'
plugins_runas_user: rabbitmq
plugins:
- rabbitmq_stompRabbitMQ as base cluster node:
rabbitmq:
server:
enabled: true
master: openstack1
{% if grains['host'] == 'openstack1' %}
role: master
{% else %}
role: slave
{% endif %}
bind:
address: 0.0.0.0
port: 5672
secret_key: rabbit_master_cookie
admin:
name: adminuser
password: pwd
cluster:
enabled: true
role: master
mode: disc
members:
- name: openstack1
host: 10.10.10.212
- name: openstack2
host: 10.10.10.213HA Queues definition:
rabbitmq:
server:
enabled: true
...
host:
'/monitor':
enabled: true
user: 'monitor'
password: 'password'
policies:
- name: HA
pattern: '^(?!amq\.).*'
definition: '{"ha-mode": "all"}'To enable support of TLS for rabbitmq-server you need to provide a path to cacert, server cert and private key:
rabbitmq:
server:
enabled: true
...
ssl:
enabled: True
key_file: /etc/rabbitmq/ssl/key.pem
cert_file: /etc/rabbitmq/ssl/cert.pem
ca_file: /etc/rabbitmq/ssl/ca.pemTo manage content of these files you can either use the following options:
rabbitmq:
server:
enabled: true
...
ssl:
enabled: True
key_file: /etc/rabbitmq/ssl/key.pem
key: |
-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-------
ca_file: /etc/rabbitmq/ssl/ca.pem
cacert_chain: |
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-------
cert_file: /etc/rabbitmq/ssl/cert.pem
cert: |
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-------Or you can use the salt.minion.cert salt state which creates all required files according to defined reclass model. See https://github.com/Mirantis/reclass-system-salt-model/tree/master/salt/minion/cert/rabbitmq for details. In this case you need just to enable ssl and nothing more:
rabbitmq:
server:
enabled: true
...
ssl:
enabled: TrueDefaut port for TLS is 5671:
rabbitmq:
server:
bind:
ssl:
port: 5671Check cluster status, example shows running cluster with 3 nodes: ctl-1, ctl-2, ctl-3
> rabbitmqctl cluster_status
Cluster status of node 'rabbit@ctl-1' ...
[{nodes,[{disc,['rabbit@ctl-1','rabbit@ctl-2','rabbit@ctl-3']}]},
{running_nodes,['rabbit@ctl-3','rabbit@ctl-2','rabbit@ctl-1']},
{partitions,[]}]
...done.Setup management user:
> rabbitmqctl add_vhost vhost
> rabbitmqctl add_user user alive
> rabbitmqctl set_permissions -p vhost user ".*" ".*" ".*"
> rabbitmqctl set_user_tags user managementEPD process is Erlang Port Mapper Daemon. It's a feature of the Erlang runtime that helps Erlang nodes to find each other. It's a pretty tiny thing and doesn't contain much state (other than "what Erlang nodes are running on this system?") so it's not a huge deal for it to still be running.
Although it's running as user rabbitmq, it was started automatically by the Erlang VM when we started. We've considered adding "epmd -kill" to our shutdown script - but that would break any other Erlang apps running on the system; it's more "global" than RabbitMQ.
