Openstack网络配置--命令行篇
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：
[[email protected]~]#source openrc.sh
2、创建public网络：
[[email protected] ~]#openstack network create --external --provider-physical-network physnet1--provider-network-type flat public

| shared | False |
| status | ACTIVE |
| subnets | |
| updated_at |2017-06-12T09:48:49Z |
+---------------------------+--------------------------------------+
给public网络添加子网：
[[email protected] ~]#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

| segment_id | None |
| service_types | |
| subnetpool_id | None |
| updated_at | 2017-06-12T09:50:56Z |
+-------------------+--------------------------------------+
3、创建私有网络：
[[email protected] ~]#openstack network create --provider-network-type vxlan demo-net
+---------------------------+--------------------------------------+
| Field | Value |
+---------------------------+--------------------------------------+
| admin_state_up | UP |
| availability_zone_hints | |

| dns_domain | None |
| 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：
[[email protected] ~]#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：
[[email protected] ~]#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 |
+-------------------------+--------------------------------------+
[[email protected] ~]#openstack router add subnet demo-router demo-subnet
[[email protected] ~]#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：
[[email protected] ~]#neutron net-list
neutron CLI is deprecated and willbe removed in the future. Use openstack CLI instead.

| id |name | tenant_id | subnets |
+---------------------+----------+---------------------+-----------------------+
| 51ec6ecc-896f-495b- | demo-net |4e79773819ff4f77980 | d9798602-0e59-4206-8a |
| bb97-e103d3d49a01 | | 2bceb4e7bf58a |53-c8a948fd020b |
| | | | 10.56.1.0/24 |
| fcc2d335-87cd-463f- | public | 4e79773819ff4f77980 | 1022cf1b-e6d9-4373-9e |
| ac1d-4b8c7c054641 | | 2bceb4e7bf58a |38-7e3b4ba1b3c4 |
| | | | 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。
