控制节点配置

建立数据库

mysql -u root -p
mysql> CREATE DATABASE neutron;
mysql> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \
  IDENTIFIED BY 'NEUTRON_DBPASS';
mysql> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \
  IDENTIFIED BY 'NEUTRON_DBPASS';

openstack创建用户

首先执行admin的环境变量脚本

openstack user create --domain default --password-prompt neutron
openstack role add --project service --user neutron admin
openstack service create --name neutron \
  --description "OpenStack Networking" network
openstack endpoint create --region RegionOne \
  network public http://controller:9696
openstack endpoint create --region RegionOne \
  network internal http://controller:9696
openstack endpoint create --region RegionOne \
  network admin http://controller:9696

neutron安装与配置

yum install openstack-neutron openstack-neutron-ml2 \
  openstack-neutron-linuxbridge ebtables

编辑配置文件/etc/neutron/neutron.conf,添加或者修改如下条目

[DEFAULT]
...
core_plugin = ml2
service_plugins =
transport_url = rabbit://openstack:RABBIT_PASS@controller
auth_strategy = keystone
notify_nova_on_port_status_changes = True
notify_nova_on_port_data_changes = True

[database]
...
connection = mysql+pymysql://neutron:NEUTRON_DBPASS@controller/neutron

[keystone_authtoken]
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = neutron
password = NEUTRON_PASS

[nova]
...
auth_url = http://controller:35357
auth_type = password
project_domain_name = Default
user_domain_name = Default
region_name = RegionOne
project_name = service
username = nova
password = NOVA_PASS

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

配置ML2插件

编辑文件/etc/neutron/plugins/ml2/ml2_conf.ini,添加或修改如下条目

[ml2]
...
type_drivers = flat,vlan
tenant_network_types =
mechanism_drivers = linuxbridge
extension_drivers = port_security
flat_networks = provider
enable_ipset = True

配置Linux bridge代理

编辑文件/etc/neutron/plugins/ml2/linuxbridge_agent.ini,添加或者修改如下条目

[linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME
[vxlan]
enable_vxlan = False
[securitygroup]
...
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

配置DHCP代理

编辑文件/etc/neutron/dhcp_agent.ini,添加或修改如下条目

[DEFAULT]
...
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = True

配置metadata代理

编辑文件/etc/neutron/metadata_agent.ini，添加或修改如下条目

[DEFAULT]
...
nova_metadata_ip = controller
metadata_proxy_shared_secret = METADATA_SECRET

为nova组件配置网络服务

编辑文件/etc/nova/nova.conf,添加或修改如下条目

[neutron]
...
url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = Default
user_domain_name = Default
region_name = RegionOne
project_name = service
username = neutron
password = NEUTRON_PASS
service_metadata_proxy = True
metadata_proxy_shared_secret = METADATA_SECRET

结束安装

网络服务需要一个ml2插件的初始配置文件，建立链接

ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

同步数据库

/bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf \
  --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron

重启nova服务

systemctl restart openstack-nova-api.service

添加开机启动

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

配置计算节点

配置neutron

yum install openstack-neutron-linuxbridge ebtables ipset

编辑配置文件/etc/neutron/neutron.conf,添加或修改如下条目

[DEFAULT]
...
transport_url = rabbit://openstack:RABBIT_PASS@controller
auth_strategy = keystone

[keystone_authtoken]
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = neutron
password = NEUTRON_PASS

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

配置 Linux bridge 代理

编辑文件/etc/neutron/plugins/ml2/linuxbridge_agent.ini,

[linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME

[vxlan]
enable_vxlan = False

[securitygroup]
...
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

配置nova组件使用网络服务

编辑文件/etc/nova/nova.conf

[neutron]
...
url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = Default
user_domain_name = Default
region_name = RegionOne
project_name = service
username = neutron
password = NEUTRON_PASS

结束安装

重启nova服务

systemctl restart openstack-nova-compute.service

添加开机启动

systemctl enable neutron-linuxbridge-agent.service
systemctl start neutron-linuxbridge-agent.service

验证操作

在controller节点上,首先执行admin的环境变量脚本，然后查看neutron的extension运行情况

neutron ext-list

列出网络代理,会显示3个control代理和一个linux代理

openstack network agent list

至此核心组件就安装完了
