4.存储节点​

  • cinder cinder-volume作为接口调用后端存储，支持多种存储类型
openstack-cinder-volume.service               enabled

5.msyql/mariadb​

用于存储集群组件信息

6.rabbitmq​

不通节点和组件之间通过AMQP高级消息队列协议进行交互

[root@vms71 ~]# grep ^tran /etc/nova/nova.conf 
transport_url=rabbit://guest:guest@192.168.26.71:5672/
[root@vms71 ~]# rabbitmqctl list_user_permissions guest
Listing permissions for user "guest"
/       .*      .*      .*
#/对应配置项为vhost,三个.*对应的权限配置项分别为配置、写、读

开启rabbitmq web管理

rabbitmq-plugins enable rabbitmq_management
systemctl restart rebbitmq-server
iptables -I INPUT 1 -p tcp --dport 15672 -j ACCEPT
#放行端口访问
#iptables -D INPUT 1
