Proivder Network

  1. 要開始 instance 前，必須先產生 virtual networks，載入 openstack 管理者 admin 環境變數。 
    [root@ip112 ~]# source admin.token
  2. 產生新的網路，–share 允許所有 projects 使用，–external 設定為對外網路。 
    [root@ip112 ~]# openstack network create  --share --external \
--provider-physical-network provider \
--provider-network-type flat provider

  3. 查詢 network，出現 provider。 
    [root@controller ~]# openstack network list
+--------------------------------------+----------+---------+
| ID                                   | Name     | Subnets |
+--------------------------------------+----------+---------+
| 0b0ebcee-057b-4798-bf73-5dd449e7879a | provider |         |
+--------------------------------------+----------+---------+
  4. 產生子網域 163.17.10.0/24，此網段為 provider 橋接對外網卡 em2 的網段。 
    [root@controller ~]# grep provider:em2 -R /etc/neutron/
/etc/neutron/plugins/ml2/linuxbridge_agent.ini:physical_interface_mappings = provider:em2

[root@ip112 ~]# openstack subnet create --network provider \
--allocation-pool start=163.17.10.113,end=163.17.10.200 \
--dns-nameserver 8.8.8.8 --gateway 163.17.10.254 \
--subnet-range 163.17.10.0/24 provider

  5. 查詢網路 provider 出現 subnet。 
    [root@controller ~]# openstack network list
+--------------------------------------+----------+--------------------------------------+
| ID                                   | Name     | Subnets                              |
+--------------------------------------+----------+--------------------------------------+
| 0b0ebcee-057b-4798-bf73-5dd449e7879a | provider | 2a7287d7-4a4f-43cc-beb2-bc9c023af929 |
+--------------------------------------+----------+--------------------------------------+
  6. 查詢網路 subnet，id 為 2a7287d7-4a4f-43cc-beb2-bc9c023af929，出現 subnet 網段為 163.17.10.0/24。 
    [root@controller ~]# openstack subnet list

+--------------------------------------+----------+--------------------------------------+----------------+
  7. 查詢 port，subnet 2a7287d7-4a4f-43cc-beb2-bc9c023af929 有一個 port，IP 為 163.17.10.113 為產生網路時設定的 IP 起點。 
    [root@controller ~]# openstack port list
+--------------------------------------+------+-------------------+----------------------------
| ID                                   | Name | MAC Address       | Fixed IP Addresses         
+--------------------------------------+------+-------------------+----------------------------
| 0e5cf9d2-eed5-41e0-978b-f816ba0e85d6 |      | fa:16:3e:d3:7a:11 | ip_address='163.17.10.113',
+--------------------------------------+------+-------------------+----------------------------
--------------------------------------------------+--------+
                                                  | Status |
--------------------------------------------------+--------+
 subnet_id='2a7287d7-4a4f-43cc-beb2-bc9c023af929' | ACTIVE |
--------------------------------------------------+--------+
  8. ping 163.17.10.113 port，成功回覆。 
    [root@controller ~]# ping -c3 163.17.10.113
