設定用戶網路

  1. 使用一般用戶 myuser，設定私有網路。 
    [root@kvm4 ~(keystone_quantum)]# source keystonerc_myuser 
[root@kvm4 ~(keystone_myuser)]#
  2. 產生名為 router1 的路由。 
    [root@kvm4 ~(keystone_myuser)]# quantum router-create router1
Created a new router:
+-----------------------+--------------------------------------+
| Field                 | Value                                |
+-----------------------+--------------------------------------+
| admin_state_up        | True                                 |
| external_gateway_info |                                      |
| id                    | 8ab14c8e-c533-47f6-ab63-fc277fada633 |
| name                  | router1                              |
| status                | ACTIVE                               |
| tenant_id             | 6c26d132e38f4b83a1d9f5a777beeb52     |
+-----------------------+--------------------------------------+
  3. 產生名為 private 的網路。 
    [root@kvm4 ~(keystone_myuser)]# quantum net-create private
Created a new network:
+-----------------+--------------------------------------+
| Field           | Value                                |
+-----------------+--------------------------------------+
| admin_state_up  | True                                 |
| id              | 48e9c08e-158d-4c6a-9623-b4eeaea5716c |

| status          | ACTIVE                               |
| subnets         |                                      |
| tenant_id       | 6c26d132e38f4b83a1d9f5a777beeb52     |
+-----------------+--------------------------------------+
  4. 產生網路 private 的子網路，名為 subpriv，網域為 192.168.32.0/24。 
    [root@kvm4 ~(keystone_myuser)]# quantum subnet-create --name subpriv private 192.168.32.0/24
Created a new subnet:
+------------------+----------------------------------------------------+
| Field            | Value                                              |
+------------------+----------------------------------------------------+
| allocation_pools | {"start": "192.168.32.2", "end": "192.168.32.254"} |
| cidr             | 192.168.32.0/24                                    |
| dns_nameservers  |                                                    |
| enable_dhcp      | True                                               |
| gateway_ip       | 192.168.32.1                                       |

| ip_version       | 4                                                  |
| name             | subpriv                                            |
| network_id       | 48e9c08e-158d-4c6a-9623-b4eeaea5716c               |
| tenant_id        | 6c26d132e38f4b83a1d9f5a777beeb52                   |
+------------------+----------------------------------------------------+
  5. 設定子網路 subpriv 的路由為 router1。 
    [root@kvm4 ~(keystone_myuser)]# quantum router-interface-add router1 subpriv
Added interface to router router1
  6. 確認 interface。 
    [root@kvm4 ~(keystone_myuser)]# quantum port-list 
+--------------------------------------+------+-------------------+-------------------------------------------------------------------------------------+
| id                                   | name | mac_address       | fixed_ips                                                                           |
+--------------------------------------+------+-------------------+-------------------------------------------------------------------------------------+
| 2083dc85-3b21-4aec-b88f-b4865fab4b4d |      | fa:16:3e:b4:ca:2d | {"subnet_id": "af75410d-6cf3-457c-a393-891641e563db", "ip_address": "192.168.32.1"} |
+--------------------------------------+------+-------------------+-------------------------------------------------------------------------------------+
  7. 為產生對外的公開網路，先匯入管理者 admin 的環境變數。 
    [root@kvm4 ~(keystone_myuser)]# source keystonerc_admin 
[root@kvm4 ~(keystone_admin)]#
  8. 產生名為 public 的公開網路。 
    [root@kvm4 ~(keystone_admin)]# quantum net-create \
--tenant-id services public -- --router:external=True
Created a new network:
+---------------------------+--------------------------------------+
| Field                     | Value                                |
+---------------------------+--------------------------------------+
| admin_state_up            | True                                 |
| id                        | f9179863-802b-4a9c-b711-206dc9a5a9b4 |
| name                      | public                               |
| provider:network_type     | local                                |
| provider:physical_network |                                      |
| provider:segmentation_id  |                                      |
| router:external           | True                                 |
| shared                    | False                                |
| status                    | ACTIVE                               |
| subnets                   |                                      |
| tenant_id                 | services                             |
+---------------------------+--------------------------------------+
  9. 產生網路 public 的子網路，名為 subpub，網域必須為目前對外網域，故為 192.168.122.0/24，gateway 要設定正確，否則無法連接外部網路。目前 192.168.122.0/24 網域已存在 dhcp，所以此子網路關閉 dhcp，且 ip 開始至結束的範圍也要避開已正在使用的 ip。 
    [root@kvm4 ~(keystone_admin)]# quantum subnet-create \
--tenant-id services \
--allocation-pool start=192.168.122.10,end=192.168.122.99 \
--gateway 192.168.122.1 \
--disable-dhcp \
--name subpub public 192.168.122.0/24
Created a new subnet:
+------------------+------------------------------------------------------+
| Field            | Value                                                |

| dns_nameservers  |                                                      |
| enable_dhcp      | False                                                |
| gateway_ip       | 192.168.122.1                                        |
| host_routes      |                                                      |

| network_id       | f9179863-802b-4a9c-b711-206dc9a5a9b4                 |
| tenant_id        | services                                             |
+------------------+------------------------------------------------------+
  10. 設定網路 public，作為路由 router1 的 gateway。 
    [root@kvm4 ~(keystone_admin)]# quantum router-gateway-set router1 public
Set gateway for router router1
  11. 列出 port，發現網路 public 的路由已被指定 ip 為 192.168.122.10。 
    [root@kvm4 ~(keystone_admin)]# quantum port-list
+--------------------------------------+------+-------------------+---------------------------------------------------------------------------------------+

+--------------------------------------+------+-------------------+---------------------------------------------------------------------------------------+
  12. 匯入一般使用者 myuser 環境變數。 
    [root@kvm4 ~(keystone_admin)]# source keystonerc_myuser 
[root@kvm4 ~(keystone_myuser)]#
  13. 在網路 public 中產生浮動 ip。 
    [root@kvm4 ~(keystone_myuser)]# quantum floatingip-create public
Created a new floatingip:
+---------------------+--------------------------------------+
