Rabbitmq for openstack

OpenStack使用消息队列在不同的服务之间协调操作和状态信息

OpenStack支持多种消息服务软件：RabbitMQ, Qpid,and ZeroMQ. 而 RabbitMQ是流行的开源消息队列系统

RabbitMQ中有一个Virtual Host，命名空间。不同命名空间之间不能够进行访问。可以简单理解我目录。

virtual host

  — 命名空间的作用

  — 多个user共同使用一个virtualhost

  — 默认命名空间是“/”

  — 不同的命名空间之间的资源是不能访问的

首先安装openstack源，就不需要epel等。。可以直接yum ，

yum install centos-release-openstack-liberty

 

The message queue service typically runs on the controller node. 

首先安装erlang

wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-7.noarch.rpm

将epel.repo文件中的baseurl取消注释，mirror那行加上注释。

wget https://github.com/rabbitmq/rabbitmq-server/releases/download/rabbitmq_v3_6_2/rabbitmq-server-3.6.2-1.noarch.rpm --no-check-certificate

rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc

yum install rabbitmq-server  socat  -y

rpm -ivh rabbitmq-server-3.6.2-1.noarch.rpm

chkconfig rabbitmq-server on

service rabbitmq-server start 

[root@controller ~]# rabbitmqctl add_user openstack RABBIT_PASS

[root@controller ~]# rabbitmqctl list_users

[root@controller ~]# rabbitmqctl list_users

yum install rabbitmq-server  socat 

# systemctl enable rabbitmq-server.service# systemctl start rabbitmq-server.service

rabbitmqctl add_user openstack RABBIT_PASSCreating user "openstack" ......done.

rabbitmqctl list_users 查看所有用户

Replace RABBIT_PASS with a suitable password.

Permit configuration, write, and read access for the openstack user:

# rabbitmqctl set_permissions openstack ".*" ".*" ".*"Setting permissions for user "openstack" in vhost "/" ......done.
