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
组件
horizon
