neutron服务的搭建配置
一、使用neutron相关命令查询网络服务的列表信息，并已下图的方式打印出来
[root@controller ~]# neutron agent-list -c binary -c agent_type -c alive
+---------------------------+--------------------+-------+
| binary | agent_type | alive |
+---------------------------+--------------------+-------+
| neutron-openvswitch-agent | Open vSwitch agent | :-) |
| neutron-metadata-agent | Metadata agent | :-) |
| neutron-l3-agent | L3 agent | :-) |
| neutron-dhcp-agent | DHCP agent | :-) |
| neutron-metadata-agent | Metadata agent | :-) |
| neutron-lbaas-agent | Loadbalancer agent | :-) |
| neutron-openvswitch-agent | Open vSwitch agent | :-) |
+---------------------------+--------------------+-------+
二、使用neutron相关命令查询网络服务的列表信息中的“binary”一列
[root@controller ~]# neutron agent-list -c binary
+---------------------------+
| binary |
+---------------------------+
| neutron-openvswitch-agent |
| neutron-metadata-agent |
| neutron-l3-agent |
| neutron-dhcp-agent |
| neutron-metadata-agent |
| neutron-lbaas-agent |
| neutron-openvswitch-agent |
+---------------------------+
三、使用neutron相关命令查询网络服务DHCP agent 的详细信息
[root@controller ~]# neutron agent-list -c binary -c id
+---------------------------+--------------------------------------+
| binary | id |
+---------------------------+--------------------------------------+
| neutron-openvswitch-agent | 020ac5f8-ff1f-4fd7-9a6d-94a81435b67d |
| neutron-metadata-agent | 314d133c-1580-45dd-8dc6-c9428ec2cecf |
| neutron-l3-agent | 3dc1dfd1-e1db-4c37-bccf-1df26ff993e7 |
| neutron-dhcp-agent | 507dc1ad-94de-4feb-95c1-a1fd1ba5f9c8 |
| neutron-metadata-agent | bfbe5b2a-7dd2-4e45-b79d-ceee3ab02881 |
| neutron-lbaas-agent | dee66fd4-6c39-4fb9-af2b-93b6f785ea60 |
| neutron-openvswitch-agent | e7e3093d-83fd-4250-8d1f-4e73be57c07b |
+---------------------------+--------------------------------------+
[root@controller ~]# neutron agent-show 507dc1ad-94de-4feb-95c1-a1fd1ba5f9c8
+---------------------+----------------------------------------------------------+
| Field | Value |
+---------------------+----------------------------------------------------------+
| admin_state_up | True |
| agent_type | DHCP agent |
| alive | True |
| availability_zone | nova |
| binary | neutron-dhcp-agent |
| configurations | { |
| | "subnets": 3, |
| | "dhcp_lease_duration": 86400, |
| | "dhcp_driver": "neutron.agent.linux.dhcp.Dnsmasq", |
| | "networks": 3, |
| | "log_agent_heartbeats": false, |
| | "ports": 8 |
| | } |

+---------------------+----------------------------------------------------------+
四、使用ovs-vswitchd管理工具的相关命令查询计算节点的网桥列表信息
[root@controller ~]# ovs-vsctl list-br
br-ex
br-int
br-tun
五、使用ovs-vswitchd管理工具的相关命令查询控制节点的网桥br-ex的端口列表信息
[root@controller ~]# ovs-vsctl list-ports br-ex
enp8s0
phy-br-ex
qg-77358d4d-5e
五、创建云主机外部网络 ext-net，子网为 ext-subnet，云主机浮动 IP 可用网段为 192.168.200.100 ~ 192.168.200.200，网关为 192.168.200.1。创建云主机内部网络 int-net1，子网为 int-subnet1，云主机子网 IP 可用网段为 10.0.0.100 ~ 10.0.0.200，网关为 10.0.0.1；创建云主机内部网络 int-net2，子网为 int-subnet2，云主机子网 IP 可用网段为 10.0.1.100 ~ 10.0.1.200，网关为 10.0.1.1。添加名为 ext-router 的路由器，添加网关在 ext-net 网络，添加内部端口到 int-net1 网络，完成内部网络 int-net1 和外部网络的连通。
六、使用 neutron 相关命令查询所创建路由器的详细信息
[root@controller ~]# neutron router-show ext-route
+-------------------------+-------------------------------------------------------------------------------------------------+
| Field | Value |
+-------------------------+-------------------------------------------------------------------------------------------------+
| admin_state_up | True |

| tenant_id | 5cb6243755824171b7e0873b18847545 |
+-------------------------+-------------------------------------------------------------------------------------------------+
[root@controller ~]#
七、使用 neutron 相关命令查询所创建子网的列表信息，并查看内网子网的详细信息
[root@controller ~]# neutron subnet-list
+--------------------------------------+-------------+------------------+---------------------------------------------+

+--------------------------------------+----------+-------------------------------------------------------+
| id | name | subnets |
+--------------------------------------+----------+-------------------------------------------------------+
| 33cd595e-cc06-4a28-b7ca-12cc2543c6f0 | ext-net | 60a96b85-5125-4e65-a954-c8847f78b10a 192.168.200.0/24 |
