　　rabbitmq信息中枢
　　
　　所有组件通信的时候 实用 AMQP 高级消息队列
　　qpid
　　rabbitmq    端口5672       sll加密 5671
192.168.1.201       h1.hequan.com     h1
192.168.1.202       h2.hequan.com     h2
192.168.1.203       h3.hequan.com     h3　　

　　在h3上操作  配置YUM源   把openstack软件包上传到openstack目录下
[openstack]
name=openstack
baseurl=file:///openstack
enabled=1
gpgcheck=0
yum clean all
yum makecache
[root@h1 yum.repos.d]# yum  install -y rabbitmq-server.noarch[root@h3 ~]# systemctl   start rabbitmq-server.service
[root@h3 ~]# systemctl   enable rabbitmq-server.service      
[root@h3 ~]# netstat -lntup | grep  5672
tcp        0      0 0.0.0.0:25672           0.0.0.0:*               LISTEN      1354/beam.smp      
tcp6       0      0 :::5672                 :::*                    LISTEN      1354/beam.smp  #使用这个[root@h1 keystone]# egrep  -v  '^$|^#'  keystone.conf  | grep rabbit
[oslo_messaging_rabbit]
rabbit_host = localhost
rabbit_port = 5672
rabbit_hosts = localhost:5672
rabbit_use_ssl = False
rabbit_userid = guest    #默认用户
rabbit_password = guest
rabbit_virtual_host = /
rabbit_ha_queues = False
[root@h3 ~]# cd /etc/rabbitmq/
[root@h3 rabbitmq]# ls
rabbitmq.config             ##配置文件
[root@h1 rabbitmq]# cat rabbitmq-env.conf
NODE_PORT=5672　　

　　

　　可以用web管理

[root@h3 rabbitmq]# rabbitmq-plugins  list   ##查看插件
[root@h3 rabbitmq]# rabbitmq-plugins   enable   rabbitmq_management  ##启用管理插件
The following plugins have been enabled:
  mochiweb
  webmachine
  rabbitmq_web_dispatch
  amqp_client
  rabbitmq_management_agent
  rabbitmq_management
Plugin configuration has changed. Restart RabbitMQ for changes to take effect.
[root@h3 rabbitmq]# systemctl  restart rabbitmq-server.service
[root@h3 rabbitmq]# netstat -lntup | grep 15672
tcp        0      0 0.0.0.0:15672     0.0.0.0:*               LISTEN      1976/beam.smp　　

　　http://192.168.1.203:15672/              用户guest  密码guest

　　元数据  metadata
　　

　　查看控制节点 网卡设置是否有问题

[root@h1 ~]# ovs-vsctl show
c34056d1-7b80-437f-b73c-5bf05258d303
    Bridge br-ex
        Port "qg-c4dff563-63"
            Interface "qg-c4dff563-63"
                type: internal
        Port "qg-62a3088b-40"
            Interface "qg-62a3088b-40"
                type: internal
        Port "qg-df2db69c-60"
            Interface "qg-df2db69c-60"
                type: internal
        Port "eth0"
            Interface "eth0"
        Port br-ex
            Interface br-ex
                type: internal
[root@h1 ~]# cat /proc/sys/net/ipv4/ip_forward           ##转发功能

[root@h2 ~]# cd /etc/nova/
[root@h2 nova]# grep metadata nova.conf
# Number of metadata items allowed per instance (integer value)

　　实例云主机   

　　可以查看metadate的设置数据
curl  htt://169.254.169.254/2009-04-04/meta-data/
hostname        
local-ipv4
public-ipv4
seruity-groups   安全组
