+————+—————————————————————————————————————————————————————————————–+先决条件
在配置OpenStack Networking(neutron)服务之前,您必须创建数据库,服务凭据和API端点。
1、创建数据库
MariaDB [(none)]> CREATE DATABASE neutron;MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron’@’localhost’ \
IDENTIFIED BY ‘openpasswd’;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron’@’%’ \
IDENTIFIED BY ‘openpasswd’;2、创建管理员访问命令行凭据
导入openstack环境变量:
# vim ~/.admin_openrcexport OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=openpasswd
export OS_AUTH_URL=http://keystone:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2# . ~/.admin_openrc
3、创建服务凭据
创建 neutron 用户密码为cisco:
# openstack user create –domain default –password-prompt neutron
User Password:
Repeat User Password:
+———————+———————————-+
| Field | Value |
+———————+———————————-+
| domain_id | default |

| id | 4ad259435d964d68bec13c7da83897ab |
| name | neutron |
| options | {} |
| password_expires_at | None |
+———————+———————————-+给neutron用户赋予管理权限:
# openstack role add –project service –user neutron admin创建neutron服务条目:
# openstack service create –name neutron \

配置自助服务网络:
在控制器节点上安装并配置网络组件。安装组件
# yum install openstack-neutron openstack-neutron-ml2 \
openstack-neutron-linuxbridge ebtables编辑nova配置文件:
# vim /etc/neutron/neutron.conf
1、In the [database] section, configure database access:
[database]
# …
connection = mysql+pymysql://neutron:openpasswd@mariadb/neutron
用您为数据库选择的密码替换NEUTRON_DBPASS。2、在[DEFAULT]部分中,启用Modular Layer 2(ML2)插件,路由器服务和overlapping IP addresses:
[DEFAULT]
# …
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = true3、在[DEFAULT]部分,配置RabbitMQ消息队列访问:
[DEFAULT]
# …
transport_url = rabbit://openstack:RABBIT_PASS@controller
transport_url = rabbit://openstack:openpasswd@nova
4、在[DEFAULT]和[keystone_authtoken]部分中,配置Identity service 访问:
[DEFAULT]
# …
auth_strategy = keystone[keystone_authtoken]
# …
auth_uri = http://keystone:5000
auth_url = http://keystone:35357
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = cisco5、在[DEFAULT]和[nova]部分中,配置网络以通知计算网络拓扑更改:
[DEFAULT]
# …
notify_nova_on_port_status_changes = true
notify_nova_on_port_data_changes = true[nova]
# …
auth_url = http://keystone:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = nova
password = cisco6、在[oslo_concurrency]部分中,配置应用锁路径:
[oslo_concurrency]
# …
lock_path = /var/lib/nova/tmp
配置模块 Layer 2 (ML2) plug-in
1、编辑 the /etc/neutron/plugins/ml2/ml2_conf.ini 文件(1)在[ml2]部分中,启用flat,VLAN和VXLAN网络:
[ml2]
# …
type_drivers = flat,vlan,vxlan
(2)在[ml2] 部分, 启用 VXLAN self-service networks:[ml2]
# …
tenant_network_types = vxlan
(3)在 [ml2] 部分中, 启用 the Linux bridge 与 layer-2 population mechanisms:[ml2]
# …
mechanism_drivers = linuxbridge,l2population配置ML2插件后,删除type_drivers选项中的值可能会导致数据库不一致
(4) [ml2] 部分中, 启用端口安全扩展驱动程序:
[ml2]
# …
extension_drivers = port_security
(5)[ml2_type_flat] 部分,将提供者虚拟网络配置为扁平网络:[ml2_type_flat]
# …
flat_networks = provider(6)[ml2_type_vxlan] 部分,为自助服务网络配置VXLAN网络标识符范围:
[ml2_type_vxlan]
# …
vni_ranges = 1:1000(7)[securitygroup] 部分,启用ipset提高安全组规则的效率:
[securitygroup]
# …
enable_ipset = true
Configure the Linux bridge agent
Linux网桥代理为实例构建第2层(桥接和交换)虚拟网络基础结构并处理安全组。编辑/etc/neutron/plugins/ml2/linuxbridge_agent.ini文件并完成以下操作:
(1)在[linux_bridge]部分中,将提供者虚拟网络映射到提供者物理网络接口:
[linux_bridge]
physical_interface_mappings = provider:ens34provider不属于 某个tenant,为各tenant提供通信承载服务的
(2)在[vxlan]部分中,启用VXLAN覆盖网络,配置处理覆盖网络的物理网络接口的IP地址,并启用第2层填充:
[vxlan]
enable_vxlan = true
local_ip = 172.16.1.7
l2_population = true将OVERLAY_INTERFACE_IP_ADDRESS替换为处理覆盖网络的底层物理网络接口的IP地址。 示例体系结构使用管理接口将流量发送到其他节点。 因此,将OVERLAY_INTERFACE_IP_ADDRESS替换为控制器节点的管理IP地址
(3)在[securitygroup]部分中,启用安全组并配置Linux网桥iptables防火墙驱动程序:
[securitygroup]
# …
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
Configure the layer-3 agent
编辑 the /etc/neutron/l3_agent.ini[DEFAULT]
# …
interface_driver = linuxbridgeConfigure the DHCP agent
DHCP代理为虚拟网络提供DHCP服务。
编辑/etc/neutron/dhcp_agent.ini文件并完成以下操作:
在[DEFAULT]部分中,配置Linux网桥接口驱动程序,Dnsmasq DHCP驱动程序,并启用隔离的元数据,以便提供商网络上的实例可以通过网络访问元数据:[DEFAULT]
# …
interface_driver = linuxbridge
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = trueConfigure the metadata agent
元数据代理为实例提供配置信息,例如凭据。
编辑/etc/neutron/metadata_agent.ini文件并完成以下操作:
在[DEFAULT]部分中,配置元数据主机和共享密钥:
[DEFAULT]
# …
nova_metadata_ip = nova
metadata_proxy_shared_secret = METADATA_SECRET在nova节点上配置:
配置Compute服务以使用网络服务
编辑/etc/nova/nova.conf文件并执行以下操作:在[neutron]部分中,配置访问参数,启用元数据代理并配置密钥:
[neutron]
# …
url = http://neutron:9696
auth_url = http://keystone:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = cisco
service_metadata_proxy = true
metadata_proxy_shared_secret = METADATA_SECRET
完成安装
网络服务初始化脚本需要一个指向ML2插件配置文件/etc/neutron/plugins/ml2/ml2_conf.ini的符号链接/etc/neutron/plugin.ini。 如果此符号链接不存在,请使用以下命令创建它:# ln -sv /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
导入数据库
# su -s /bin/sh -c “neutron-db-manage –config-file /etc/neutron/neutron.conf \
–config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head” neutronRestart the Compute API service:
# systemctl restart openstack-nova-api.service
Start the Networking services and configure them to start when the system boots.For both networking options:
# systemctl enable neutron-server.service \
neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
neutron-metadata-agent.service
# systemctl start neutron-server.service \
neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
neutron-metadata-agent.service
For networking option 2, also enable and start the layer-3 service:# systemctl enable neutron-l3-agent.service
# systemctl start neutron-l3-agent.service
