neutron ext-list报错

各位大侠，安装过程中出现问题，寻求解决。

十二、安装网络

在安装配置openstack neutron之前，需要创建数据库、服务认证、 API endpoints.

安装准备

1.创建数据库

a.登录mysql
# mysql -u root -p

b.创建 neutron 数据库:
CREATE DATABASE neutron;

c.授权
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \
IDENTIFIED BY ' QcIH2mIjyF';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \
IDENTIFIED BY ' QcIH2mIjyF';

d.退出mysql
quit;

2.环境变量生效
# source /openstack/admin-openrc.sh

3.创建服务凭证a.创建neutron用户:
# keystone user-create --name neutron --pass QcIH2mIjyF
+----------+----------------------------------+
| Property |             Value             |
+----------+----------------------------------+
|  email |                               |
| enabled  |             True             |
| id | fc0ab7ada3f54d818b06e1bfde36eff7 |
| name |          neutron             |
| username |          neutron             |
+----------+----------------------------------+

b.给neutron用户授予admin角色
# keystone user-role-add --user neutron --tenant service --role admin
Note
This command provides no output.

c.创建neutron 服务实例
# keystone service-create --name neutron --type network \
--description "OpenStack Networking"
+-------------+----------------------------------+
| Property  |             Value             |
+-------------+----------------------------------+
| description |    OpenStack Networking    |
| enabled |             True             |
|    id    | a12b45e09fc44fafaaa0ed75bd9db31f |
|    name |          neutron             |
|    type |          network             |
+-------------+----------------------------------+

4.创建网路服务 API endpoints:
# keystone endpoint-create \
--service-id $(keystone service-list | awk '/ network / {print $2}') \
--publicurl http://controller:9696 \
--adminurl http://controller:9696 \
--internalurl http://controller:9696 \
--region regionOne
+-------------+----------------------------------+
| Property  |             Value             |
+-------------+----------------------------------+
| adminurl  |    http://controller:9696    |
|    id    | 5ea03b755bd84053889e6953af8b5a25 |
| internalurl |    http://controller:9696    |
|  publicurl  |    http://controller:9696    |
| region |          regionOne          |
|  service_id | a12b45e09fc44fafaaa0ed75bd9db31f |
+-------------+----------------------------------+

安装网络组件安装组件
# apt-get install -y neutron-server neutron-plugin-ml2 python-neutronclient

配置网络服务组件

备注：
运行下面指令获得nova_admin_tenant_id
$ source /openstack/admin-openrc.sh
$ keystone tenant-get service
+-------------+----------------------------------+
| Property  |             Value             |
+-------------+----------------------------------+
| description |       Service Tenant       |
| enabled |             True             |
|    id    | 84742719137b43a5aa979f1a205ad781 |
|    name |          service             |
+-------------+----------------------------------+

网络服务器组件配置包括数据库，认证机制，消息代理，拓扑改变报警，和插件。
编辑文件 /etc/neutron/neutron.conf，完成下面下面配置
# vi /etc/neutron/neutron.conf

[DEFAULT]
...
rpc_backend = rabbit
rabbit_host = controller
rabbit_password = QcIH2mIjyF

auth_strategy = keystone

service_plugins = router
allow_overlapping_ips = True

notify_nova_on_port_status_changes = True
notify_nova_on_port_data_changes = True
nova_url = http://controller:8774/v2
nova_admin_auth_url = http://controller:35357/v2.0
nova_region_name = regionOne
nova_admin_username = nova
nova_admin_tenant_id = 84742719137b43a5aa979f1a205ad781
nova_admin_password = QcIH2mIjyF

verbose = True

[keystone_authtoken]
auth_uri = http://controller:5000/v2.0
identity_uri = http://controller:35357
admin_tenant_name = service
admin_user = neutron
admin_password = QcIH2mIjyF

[database]
connection = mysql://neutron: QcIH2mIjyF@controller/neutron

配置Modular Layer 2 (ML2) 插件

ML2插件使用 Open vSwitch (OVS)机制，为实例创建虚拟网络框架。尽管如此控制节点不需要OVS 组件，因为它不处理实例网络互通
编辑文件 /etc/neutron/plugins/ml2/ml2_conf.ini，完成下面步骤
# vi /etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]
...
type_drivers = flat,gre
tenant_network_types = gre
mechanism_drivers = openvswitch

[ml2_type_gre]
...
tunnel_id_ranges = 1:1000

[securitygroup]
...
enable_security_group = True
enable_ipset = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

使用网络配置计算

默认情况下，分配包配置使用传统网络计算。你不许通过网络重新配置管理网络计算
编辑文件 /etc/nova/nova.conf，完成下面操作
# vi /etc/nova/nova.conf

[DEFAULT]
...
network_api_class = nova.network.neutronv2.api.API
security_group_api = neutron
linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriver
firewall_driver = nova.virt.firewall.NoopFirewallDriver

[neutron]
url = http://controller:9696
auth_strategy = keystone
admin_auth_url = http://controller:35357/v2.0
admin_tenant_name = service
admin_username = neutron
admin_password = QcIH2mIjyF

完成安装
1.同步数据库

Perform these commands on the controller node.
1. Source the admin credentials to gain access to admin-only CLI commands:
$ source /openstack/admin-openrc.sh

2. List loaded extensions to verify successful launch of the neutron-server process:
$ neutron ext-list
