openstack搭建10、 Neutron控制/網路節點叢集

阿新 • • 發佈：2021-01-21

10、 Neutron控制/網路節點叢集
neutron-server 埠9696 api：接受和響應外部的網路管理請求
neutron-linuxbridge-agent: 負責建立橋接網絡卡
neturon-dhcp-agent: 負責分配IP
neturon-metadata-agent: 配合Nova-metadata-api實現虛擬機器的定製化操作
L3-agent 實現三層網路vxlan（網路層）
**Neutron Server:**對外提供Openstack網路API，接收請求，並呼叫Plugin處理請求。
**Plugin:**處理Neturon Server發來的請求，維護Openstack邏輯網路狀態，並呼叫Agent處理請求。
**Agent:**處理Plugin的請求，負責在network provider上真正實現各種網路功能。
**Network provider:**提供網路服務的虛擬或物理網路裝置，例如Linux Bridge,Open vSwitch或者其他支援Neutron的物理交換機。
**Queue:**Neutron Server,Plugin和Agent之間通過Messagings Queue通訊和呼叫。
**Database:**存放OpenStack的網路狀態資訊，包括Network，Subnet,Port,Router等。

10.1 建立neutron資料庫（在任意控制節點建立資料庫，後臺資料自動同步）

[root@controller1:/root]# mysql -uroot -p"123456"
MariaDB [(none)]> CREATE DATABASE neutron;
Query OK, 1 row affected (0.009 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'NEUTRON_szh';
Query OK, 0 rows affected (0.009
 
 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'NEUTRON_szh';
Query OK, 0 rows affected (0.011 sec)
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> exit
Bye

10.2 建立neutron使用者、賦權、服務實體

[root@controller1:/root]# source openrc

控制演算法的劃分（自適應控制、預測控制、模糊控制等，PID等；蟻群演算法、神經網路，還有機器學習、人工智慧中的很多方法）

　一般來說，控制器的設計，分為控制框架的選取，跟引數的優化。自適應控制、預測控制、模糊控制等，跟PID一樣，是控制演算法（我習慣稱為控制框架）。
