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）：
|
1
2
3
|
# yum install rabbitmq-server
# systemctl enable rabbitmq-server.service
# systemctl start rabbitmq-server.service
|
|
1
2
|
[root@servera ~]
# 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)
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17

22
23
|
root@servera ~]
# 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：
|
1
2
3
4
5
|
#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
|
