I. Creating an external network

• Load Environment

source admin-openrc.sh

• Create a network

Neutron net-create ext-net--shared--Router:External--provider:Physical_network External--provider:Network_type FlatCreatedA newNetwork:+---------------------------+--------------------------------------+|Field|Value|+---------------------------+--------------------------------------+| admin_state_up | True|| id | 0e62efcd-8cee- $C7-B163-D8DF05C3C5AD || mtu |  the|| name | provider || port_security_enabled | True||provider:Network_type| flat ||provider:Physical_network| provider ||provider:segmentation_id | ||Router:External |False|| shared | True|| status | ACTIVE|| subnets ||| tenant_id | d84313397390425c8ed50b2f6e18d092 |+---------------------------+--------------------------------------+

Two. Create a subnet on the external network

Neutron subnet-createExt-netExternal_network_cidr--Name ext-subnet   --Allocation-poolStart=Floating_ip_start,end=Floating_ip_end--Disable-dhcp --Gateway External_network_gateway#EXTERNAL_NETWORK_CIDRFor available Internet IP segment (**Must be able to surf the internet**), such as203.0. 113. 0/ -, Floating_ip_start,end=Floating_ip_end refers to the starting IP and terminating IP of the floating IP, as203.0. 113. 203.0. 113. 156, External_network_gateway is a gateway, typically the first IP of a network segment such as203.0. 113. 1

For example:

Neutron subnet-create ext-net203.0. 113. 0/ ---name ext-subnet--allocation-pool start=203.0. 113., end=203.0. 113. 156--disable-dhcp--gateway203.0. 113. 1CreatedA newSubnet:+-------------------+----------------------------------------------------+|Field|Value|+-------------------+----------------------------------------------------+| allocation_pools |{"Start":"203.0.113.101","End":"203.0.113.250"} || cidr | 203.0. 113. 0/ -|| dns_nameservers | 8.8. 4. 4|| enable_dhcp | True|| gateway_ip | 203.0. 113. 1|| host_routes ||| id | 5cc70da8-4ee7-4565-be53-b9c011fca011 || ip_version | 4|| ipv6_address_mode ||| ipv6_ra_mode ||| name | provider || network_id | 0e62efcd-8cee- $C7-B163-D8DF05C3C5AD || subnetpool_id ||| tenant_id | d84313397390425c8ed50b2f6e18d092 |+-------------------+----------------------------------------------------+

Three. Create a Tenant (project) network

• Load environment ( especially important )

source demo-openrc.sh

• Create a Tenant (project) network

net-create demo-net

• Create a Tenant (project) network subnet

neutron subnet-create demo-net TENANT_NETWORK_CIDR  --name demo-subnet--gateway TENANT_NETWORK_GATEWAY#TENANT_NETWORK_CIDR为租户（project）网络，一般用192.168.**，**/24，TENANT_NETWORK_GATEWAY为网管一般为192.168.**.1，可以根据自己的需求设置。

For example:

Neutron subnet-create demo-net 192.168.1.0/24--name demo-subnet--gateway 192.168.1.1Created a new subnet:+-------------------+------------------------------------------------+| Field | Value |+-------------------+------------------------------------------------+| Allocation_pools | {"Start": "172.16.1.2", "End": "172.16.1.254"} | | CIDR | 192.168.1.0/24 | | Dns_nameservers | || Enable_dhcp | True | | Gateway_IP | 192.168.1.1 | | Host_routes | || ID | 3482f524-8bff-4871-80d4-5774c2730728 | | Ip_Version | 4 | | IPv6_address_mode | || IPv6_ra_mode | || name | demo-subnet | | Network_id | 7c6f9b37-76b4-463e-98d8-27e5686ed083 | | tenant_ID | f5b2ccaa75ac413591f12fcaa096aa5c |+-------------------+------------------------------------------------+

Four. Create tenant routes and attach extranet and tenant networks to routes

• Create a tenant route

neutron router-create demo-router

• Connecting a router to a tenant network

neutron router-interface-addinterface bff6605d-824c-41f9-b744-21to router demo-router.

• Connect the router to the external network by setting the gateway

neutron router-gateway-set demo-router ext-net

Five. Verification (self-successful 2 times, failed 3 times, no words)

• Control node Ping 203.0.113.100 (can ping pass)

ping4203.0.113.100

Create an instance

(In fact, long forgotten, has been created with the Web page, the temperature is a bit)
I. Environment

• Load Environment

source admin-openrc.sh

• Generate and add a key pair

nova keypair-add demo-key

Two. Create an instance

• List flavors, mirroring with network, security group

nova flavor-listnova image-listneutron net-listnova secgroup-list

• Create an instance (demo_net_id is the ID of the Demo-net network listed above)

Nova Boot --Flavor M1.Tiny --Image Cirros-0.3.4-x86_64 --Nic Net-id=demo_net_id --Security-Group default --Key-name Demo-Key test1

• Listing instances

nova list+------------------------------------+---------------+--------+------------+-------------+----------------------+|ID                                  |Name           | Status | Task State | Power State | Networks             |+-------------------------------------+--------------+--------+------------+-------------+----------------------+|02caa2ca-d6e6-46fd-b4a9-e432bcde2e6a|test1          | ACTIVE | -          | Running     | demo-net=192.168.1.3 |+------------------------------------+---------------+--------+------------+-------------+----------------------+

• Access the instance through the browser (load the URL into the browser for viewing)

nova get-vnc-console test1 novnc+-------+---------------------------------------------------------------------------------+| Field | Value                                                                           |+-------+---------------------------------------------------------------------------------+| type  | novnc                                                                           || url   | http://controller:6080/vnc_auto.html?token=5eeccb47-525c-4918-ac2a-3ad1e9f1f493 |+-------+---------------------------------------------------------------------------------+

• Instance user name: Cirros, Password: cubswin:), no problem, in the console ping Baidu and other external network can be ping through

  Note: Previously built, can run, if there are some questions written above, thank you for pointing out.
