来源：互联网发布：ubuntu ntp服务器设置编辑：程序博客网时间：2024/06/06 13:02

前面讲过网络配置horizon篇，本文讲使用命令行配置openstack网络。

1、首先source openers.sh脚本，该脚本中是一些环境变量:

运行该脚本，即可通过命令行来管理云资源了：

[root@cloud~]#source openrc.sh

2、创建public网络：

[root@cloud ~]#openstack network create --external --provider-physical-network physnet1--provider-network-type flat public

| provider:segmentation_id | None |

| qos_policy_id | None |

| revision_number | 3 |

| router:external | External |

| segments |None |

| shared | False |

| status | ACTIVE |

| subnets | |

| updated_at |2017-06-12T09:48:49Z |

+---------------------------+--------------------------------------+

给public网络添加子网：

[root@cloud ~]#openstack subnet create --no-dhcp --allocation-poolstart=192.168.60.30,end=192.168.60.90 --network public --subnet-range192.168.60.0/24 --gateway 192.168.60.247 public-subnet

| allocation_pools | 192.168.60.30-192.168.60.90 |

| cidr | 192.168.60.0/24 |

| segment_id | None |

| service_types | |

| subnetpool_id | None |

| updated_at | 2017-06-12T09:50:56Z |

+-------------------+--------------------------------------+

3、创建私有网络：

[root@cloud ~]#openstack network create --provider-network-type vxlan demo-net

+---------------------------+--------------------------------------+

| Field | Value |

+---------------------------+--------------------------------------+

| admin_state_up | UP |

| id | 51ec6ecc-896f-495b-bb97-e103d3d49a01 |

| ipv4_address_scope | None |

| ipv6_address_scope | None |

| is_default | None |

| mtu | 1450 |

| name | demo-net |

| port_security_enabled | False |

| project_id |4e79773819ff4f779802bceb4e7bf58a |

| provider:network_type | vxlan |

| provider:physical_network | None |

| provider:segmentation_id | 79 |

| qos_policy_id | None |

| revision_number | 2 |

| router:external | Internal |

| segments |None |

| shared | False |

| status | ACTIVE |

| subnets | |

| updated_at |2017-06-12T09:52:07Z |

+---------------------------+--------------------------------------+

给私有网络添加子网：

[root@cloud ~]#openstack subnet create --subnet-range 10.56.1.0/24 --network demo-net--gateway 10.56.1.1 --dns-nameserver 8.8.8.8 demo-subnet

+-------------------+--------------------------------------+

| Field | Value |

+-------------------+--------------------------------------+

| allocation_pools | 10.56.1.2-10.56.1.254 |

| cidr | 10.56.1.0/24 |

| created_at | 2017-06-12T09:52:25Z |

| description | |

| dns_nameservers | 8.8.8.8 |

| enable_dhcp | True |

| gateway_ip | 10.56.1.1 |

| host_routes | |

| id |d9798602-0e59-4206-8a53-c8a948fd020b |

| ip_version | 4 |

| ipv6_address_mode | None |

| ipv6_ra_mode | None |

| name | demo-subnet |

| network_id | 51ec6ecc-896f-495b-bb97-e103d3d49a01 |

| project_id | 4e79773819ff4f779802bceb4e7bf58a |

| revision_number | 2 |

| segment_id | None |

| service_types | |

| subnetpool_id | None |

| updated_at | 2017-06-12T09:52:25Z |

+-------------------+--------------------------------------+

4、给外网和私网之间添加路由：

[root@cloud ~]#openstack router create demo-router

+-------------------------+--------------------------------------+

| Field | Value |

+-------------------------+--------------------------------------+

| admin_state_up | UP |

| availability_zone_hints | |

| availability_zones | |

| created_at |2017-06-12T09:52:38Z |

| description | |

| distributed | False |

| external_gateway_info | None |

| flavor_id | None |

| ha | False |

| id | 7f7a7d73-d640-4c40-b41c-c0a7adc2e018 |

| name | demo-router |

| project_id |4e79773819ff4f779802bceb4e7bf58a |

| revision_number | None |

| routes | |

| status |ACTIVE |

| updated_at |2017-06-12T09:52:38Z |

+-------------------------+--------------------------------------+

[root@cloud ~]#openstack router add subnet demo-router demo-subnet

[root@cloud ~]#openstack router set --external-gateway public demo-router

5、通过下面的命令可以查询刚刚所建的网络信息：

[root@cloud ~]#neutron net-list

neutron CLI is deprecated and willbe removed in the future. Use openstack CLI instead.

+---------------------+----------+---------------------+-----------------------+

+---------------------+----------+---------------------+-----------------------+

| | | | 10.56.1.0/24 |

| | | | 192.168.60.0/24 |

+---------------------+----------+---------------------+-----------------------+

6、登到dashboard上面去看network topology：

至此，使用命令行创建简单的网络拓扑结束。
