[DEFAULT]
nova_metadata_host = 192.168.56.11

metadata_proxy_shared_secret = unixhot.com

12、Neutron相关配置在nova.conf

[root@linux-node1 ~]# vim /etc/nova/nova.conf
[neutron]
url = http://192.168.56.11:9696
auth_url = http://192.168.56.11:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron
service_metadata_proxy = True
metadata_proxy_shared_secret = unixhot.com

[root@linux-node1 ~]# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

13、同步数据库

[root@linux-node1 ~]# 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" neutron

14、重启计算API 服务

systemctl restart openstack-nova-api.service

15、启动网络服务并配置他们开机自启动

# 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

16、Neutron服务注册

# openstack service create --name neutron --description "OpenStack Networking" network
创建endpoint
# openstack endpoint create --region RegionOne network public http://192.168.56.11:9696
# openstack endpoint create --region RegionOne network internal http://192.168.56.11:9696
# openstack endpoint create --region RegionOne network admin http://192.168.56.11:9696

auth_uri = http://192.168.56.11:5000
auth_url = http://192.168.56.11:35357
memcached_servers = 192.168.56.11:
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron

3、RabbitMQ相关设置

[root@linux-node2 ~]# vim /etc/neutron/neutron.conf
[DEFAULT]
transport_url = rabbit://openstack:openstack@192.168.56.11
#请注意是在DEFAULT配置栏目下，因为该配置文件有多个transport_url的配置

4、锁路径

[oslo_concurrency]
lock_path = /var/lib/neutron/tmp

5、配置LinuxBridge配置

[root@linux-node1 ~]# scp /etc/neutron/plugins/ml2/linuxbridge_agent.ini 192.168.56.12:/etc/neutron/plugins/ml2/

6、设置计算节点的nova.conf

[root@linux-node2 ~]# vim /etc/nova/nova.conf
[neutron]
url = http://192.168.56.11:9696
auth_url = http://192.168.56.11:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron

7、重启计算服务

[root@linux-node2 ~]# systemctl restart openstack-nova-compute.service

8、启动计算节点linuxbridge-agent

[root@linux-node2 ~]# systemctl enable neutron-linuxbridge-agent.service
[root@linux-node2 ~]# systemctl start neutron-linuxbridge-agent.service

9、在控制节点上测试Neutron安装
