openstack网络管理命令
1、获取网络列表
[root@cc ~(keystone_admin)]# neutron net-list +--------------------------------------+----------+-----------------------------------------------------+ | id | name | subnets | +--------------------------------------+----------+-----------------------------------------------------+ | afde2904-9951-44b9-a3a2-f23b0b68a60b | flat | abb07ddd-110d-408d-8879-e0fc0d640b63 172.16.80.0/24 | | 1d7ede32-66aa-41c0-bec0-1b93a5741e46 | vlan1681 | 1c06ea64-5d1f-49ec-804e-97d44974c583 172.16.81.0/24 | +--------------------------------------+----------+-----------------------------------------------------+
2、查看某个网络的信息
[root@cc ~(keystone_admin)]# neutron net-show afde2904-9951-44b9-a3a2-f23b0b68a60b +---------------------------+--------------------------------------+ | Field | Value | +---------------------------+--------------------------------------+ | admin_state_up | True | | id | afde2904-9951-44b9-a3a2-f23b0b68a60b | | name | flat | | provider | False | | provider:network_type | flat | | provider:physical_network | physnet1 | | provider:segmentation_id | | | router:external | False | | shared | False | | status | ACTIVE | | subnets | abb07ddd-110d-408d-8879-e0fc0d640b63 | | tenant_id | cbeb053466384fd4a3eaa4fced6e307a | +---------------------------+--------------------------------------+
3、创建公网
[root@station140 ~(network_admin)]# neutron net-create --router:external=true pub1 Created a new network: +---------------------------+--------------------------------------+ | Field | Value | +---------------------------+--------------------------------------+ | admin_state_up | True | | id | aebe75f0-6013-4a5e-bbd9-cb81e1f017bc | | name | pub1 | | provider:network_type | local | | provider:physical_network | | | provider:segmentation_id | | | router:external | True | | shared | False | | status | ACTIVE | | subnets | | | tenant_id | e3a71a59840c4e88b8740b789c3afb9c | +---------------------------+--------------------------------------+ 注: 参数 --router:external=true 表示创建的是公网网络
4、创建私有网络，指定tenant
[root@cc07 ~]# neutron net-create hzb-privnet1 --tenant-id=26a8e1feb372493d831c19d4d9e28d73 Created a new network: +---------------------------+--------------------------------------+ | Field | Value | +---------------------------+--------------------------------------+ | admin_state_up | True | | availability_zone_hints | | | availability_zones | | | created_at | 2018-10-25T06:20:35 | | description | | | id | 2193270e-c4c9-469c-99ae-87ebdb4ba535 | | ipv4_address_scope | | | ipv6_address_scope | | | mtu | 1500 | | name | hzb-privnet1 | | port_security_enabled | True | | provider | False | | provider:network_type | vlan | | provider:physical_network | physnet1 | | provider:segmentation_id | 219 | | qos_policy_id | | | router:external | False | | shared | False | | status | ACTIVE | | subnets | | | tags | | | tenant_id | 26a8e1feb372493d831c19d4d9e28d73 | | updated_at | 2018-10-25T06:20:35 | +---------------------------+--------------------------------------+
5、创建hzb-privnet1的子网
[root@cc07 ~]# neutron subnet-create --name hzb-sub-net1 --allocation-pool start=10.30.0.50,end=10.30.0.100 --no-gateway --ip-version 4 hzb-privnet1 10.30.0.0/24 Created a new subnet: +-------------------+-----------------------------------------------+ | Field | Value | +-------------------+-----------------------------------------------+ | allocation_pools | {"start": "10.30.0.50", "end": "10.30.0.100"} | | cidr | 10.30.0.0/24 | | created_at | 2018-10-25T06:25:23 | | description | | | dns_nameservers | | | enable_dhcp | True | | gateway_ip | | | host_routes | | | id | 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 | | ip_version | 4 | | ipv6_address_mode | | | ipv6_ra_mode | | | name | hzb-sub-net1 | | network_id | 2193270e-c4c9-469c-99ae-87ebdb4ba535 | | subnetpool_id | | | tenant_id | ff2958aa964541679833ddbcc503c5d2 | | updated_at | 2018-10-25T06:25:23 | +-------------------+-----------------------------------------------+
6、列出网络hzb-privnet1的子网
[root@cc07 ~]# neutron subnet-list --network_id=2193270e-c4c9-469c-99ae-87ebdb4ba535 +--------------------------------------+--------------+--------------+-----------------------------------------------+ | id | name | cidr | allocation_pools | +--------------------------------------+--------------+--------------+-----------------------------------------------+ | 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 | hzb-sub-net1 | 10.30.0.0/24 | {"start": "10.30.0.50", "end": "10.30.0.100"} | +--------------------------------------+--------------+--------------+-----------------------------------------------+
7、查看某一子网的详情
[root@cc07 ~]# neutron subnet-show 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 +-------------------+-----------------------------------------------+ | Field | Value | +-------------------+-----------------------------------------------+ | allocation_pools | {"start": "10.30.0.50", "end": "10.30.0.100"} | | cidr | 10.30.0.0/24 | | created_at | 2018-10-25T06:25:23 | | description | | | dns_nameservers | | | enable_dhcp | True | | gateway_ip | | | host_routes | | | id | 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 | | ip_version | 4 | | ipv6_address_mode | | | ipv6_ra_mode | | | name | hzb-sub-net1 | | network_id | 2193270e-c4c9-469c-99ae-87ebdb4ba535 | | subnetpool_id | | | tenant_id | ff2958aa964541679833ddbcc503c5d2 | | updated_at | 2018-10-25T06:25:23 | +-------------------+-----------------------------------------------+
8、更新子网
[root@cc07 ~]# neutron subnet-update 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 --dns-nameserver 8.8.8.8 --allocation-pool start=10.30.0.60,end=10.30.0.90 Updated subnet: 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 [root@cc07 ~]# neutron subnet-show 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 +-------------------+----------------------------------------------+ | Field | Value | +-------------------+----------------------------------------------+ | allocation_pools | {"start": "10.30.0.60", "end": "10.30.0.90"} | | cidr | 10.30.0.0/24 | | created_at | 2018-10-25T06:25:23 | | description | | | dns_nameservers | 8.8.8.8 | | enable_dhcp | True | | gateway_ip | | | host_routes | | | id | 0ba19972-c2f6-4cbb-80f6-a642a2f698a8 | | ip_version | 4 | | ipv6_address_mode | | | ipv6_ra_mode | | | name | hzb-sub-net1 | | network_id | 2193270e-c4c9-469c-99ae-87ebdb4ba535 | | subnetpool_id | | | tenant_id | ff2958aa964541679833ddbcc503c5d2 | | updated_at | 2018-10-25T06:42:27 | +-------------------+----------------------------------------------+
9、删除子网
neutron subnet-delete hzb-sub-net1
10、清理被占用的子网，比如要清理掉74网段的
