一、简介
所有Red Hat Openstack服务之间都使用RabbitMQ(统一消息系统)进行通讯。
默认RabbitMQ监听5672端口，RabbitMQ支持基于账户与密码的访问并可以实现SSL加密，如果启用了SSL加密则端口需要修改为5671。
RabbitMQ comes with default built-in settings which will most likely be sufficient for running your RabbitMQ server effectively. If it runs fine, then you probably don‘t need any configuration at all.
二、配置
安装（以Redhat7/CentOS7为例）：
# yum install rabbitmq-server # systemctl enable rabbitmq-server.service # systemctl start rabbitmq-server.service
[[email protected] ~]# cat /etc/rabbitmq/rabbitmq-env.conf NODE_PORT=5672
environment variables：
----define ports, file locations and names (taken from the shell, or set in the rabbitmq-env.conf file)
[email protected] ~]# cat /etc/rabbitmq/rabbitmq.config
% This file managed by Puppet
% Template Path: rabbitmq/templates/rabbitmq.config
[
{rabbit, [
{tcp_listen_options,
[binary,
{packet, raw},
{reuseaddr, true},
{backlog, 128},
{nodelay, true},
{exit_on_close, false}]
},
{loopback_users, []},
{tcp_listen_options, [binary,{packet, raw},{reuseaddr, true},{backlog, 128},{nodelay, true},{exit_on_close, false},{keepalive, true}]},
{default_user, <<"guest">>},
{default_pass, <<"guest">>}
]},
{kernel, [
]}
].
% EOF
configuration file：
----defines server component settings for permissions, limits and clusters, and also plugin settings.
三、
RabbitMQ通过其他组件来调用，确认每个Openstack组件都正确的配置了RabbitMQ：
#grep rabbit /etc/keystone/keystone.conf #grep rabbit /etc/nova/nova.conf #grep rabbit /etc/cinder/cinder.conf #grep rabbit /etc/neutron/neutron.conf #grep rabbit /etc/glance/glance-api.conf
