[DEFAULT]
nova_metadata_host = 192.168.8.11
metadata_proxy_shared_secret = iirwt
12.Neutron相关配置在nova.conf
[root@linux-node1 ~]# vim /etc/nova/nova.conf
[neutron]
url = http://192.168.8.11:9696
auth_url = http://192.168.8.11:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron

metadata_proxy_shared_secret = iirwt
[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 \
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
14.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://192.168.8.11:9696
openstack endpoint create --region RegionOne network internal http://192.168.8.11:9696
openstack endpoint create --region RegionOne network admin http://192.168.8.11:9696
15.测试Neutron安装
[root@linux-node1 ~]# openstack network agent list
[root@linux-node1 ~]# neutron agent-list
二. Neutron计算节点部署
安装软件包
[root@linux-node2 ~]# yum install -yopenstack-neutron-linuxbridge ebtables ipset

[root@linux-node2 ~]# vim /etc/neutron/neutron.conf
[DEFAULT]
…
auth_strategy = keystone
[keystone_authtoken]
auth_uri = http://192.168.8.11:5000
auth_url = http://192.168.8.11:35357
memcached_servers = 192.168.8.11:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = neutron
2.RabbitMQ相关设置
[root@linux-node2 ~]# vim /etc/neutron/neutron.conf
[DEFAULT]
transport_url = rabbit://openstack:[email protected]
#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 192.168.8.12:/etc/neutron/plugins/ml2/
5.设置计算节点的nova.conf
[root@linux-node2 ~]# vim /etc/nova/nova.conf
[neutron]
url = http://192.168.8.11:9696
auth_url = http://192.168.8.11:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = neutron
重启计算服务
[root@linux-node2 ~]# systemctl restart openstack-nova-compute.service
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
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
