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://192.168.56.11:9696 # 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
15.测试Neutron安装
[root@linux-node1 ~]# openstack network agent list
Neutron计算节点部署
安装软件包
[root@linux-node2 ~]# yum install -y openstack-neutron openstack-neutron-linuxbridge ebtables

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 192.168.56.12:/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://192.168.56.11:9696 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
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
