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

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

13.重启计算API 服务

# systemctl restart openstack-nova-api.service

启动网络服务并配置他们开机自启动。

# systemctl enable neutron-server.service \

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

3.锁路径

[oslo_concurrency]

lock_path = /var/lib/neutron/tmp

4.配置LinuxBridge配置

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

5.设置计算节点的nova.conf

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

在控制节点上测试Neutron安装

[root@linux-node1 ~]# source admin-openstack.sh

[root@linux-node1 ~]# openstack network agent list

看是否有linux-node2.example.com的Linux bridge agent
