七、【openstack train安装】第六步-安装neutron

1、安装neutron软件包和配置

[root@controller ~]# openstack user create --domain default --password-prompt neutron

[root@controller ~]# openstack role add --project service --user neutron admin

[root@controller ~]# openstack service create --name neutron   --description "OpenStack Networking" network

[root@controller ~]# openstack endpoint create --region RegionOne   network public http://controller:9696

[root@controller ~]# openstack endpoint create --region RegionOne   network internal http://controller:9696

[root@controller ~]# openstack endpoint create --region RegionOne   network admin http://controller:9696

[root@controller ~]# yum install openstack-neutron openstack-neutron-ml2   openstack-neutron-linuxbridge ebtables -y

[root@controller ~]# vi /etc/neutron/neutron.conf

[DEFAULT]

core_plugin = ml2

service_plugins = router

allow_overlapping_ips = true

transport_url = rabbit://openstack:123456@controller

auth_strategy = keystone

notify_nova_on_port_status_changes = true

notify_nova_on_port_data_changes = true

[cors]

[database]

connection = mysql+pymysql://neutron:123456@controller/neutron

[keystone_authtoken]

www_authenticate_uri = http://controller:5000

auth_url = http://controller:5000

memcached_servers = controller:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = neutron

password = 123456

[oslo_concurrency]

lock_path = /var/lib/neutron/tmp

[oslo_messaging_amqp]

[oslo_messaging_kafka]

[oslo_messaging_notifications]

[oslo_messaging_rabbit]

[oslo_middleware]

[oslo_policy]

[privsep]

[ssl]

[nova]

auth_url = http://controller:5000

auth_type = password

project_domain_name = default

user_domain_name = default

region_name = RegionOne

project_name = service

username = nova

password = 123456

[root@controller ~]# vi /etc/neutron/plugins/ml2/ml2_conf.ini

[DEFAULT]

[ml2]

type_drivers = flat,vlan,vxlan

tenant_network_types = vxlan

mechanism_drivers = linuxbridge,l2population

extension_drivers = port_security

[ml2_type_flat]

flat_networks = provider

[ml2_type_vxlan]

vni_ranges = 1:1000

[securitygroup]

enable_ipset = true

[root@controller ~]# vi /etc/neutron/plugins/ml2/linuxbridge_agent.ini

[DEFAULT]

[linux_bridge]

physical_interface_mappings = provider:em1

[vxlan]

enable_vxlan = true

local_ip = 10.0.66.107

l2_population = true

[securitygroup]

enable_security_group = true

firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

[root@controller ~]# vi /etc/neutron/l3_agent.ini

[DEFAULT]

interface_driver = linuxbridge

[root@controller ~]# vi /etc/neutron/dhcp_agent.ini

[DEFAULT]

interface_driver = linuxbridge

dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq

enable_isolated_metadata = true

[root@controller ~]# vi /etc/neutron/metadata_agent.ini

[DEFAULT]

nova_metadata_host = controller

metadata_proxy_shared_secret = 123456

[cache]

计算服务加上网络服务相关信息

[root@controller ~]# vi /etc/nova/nova.conf

...

[neutron]

auth_url = http://controller:5000

auth_type = password

project_domain_name = default

user_domain_name = default

region_name = RegionOne

project_name = service

username = neutron

password = 123456

service_metadata_proxy = true

metadata_proxy_shared_secret = 123456

检查配置是否映射，没有的话添加映射

[root@controller ~]# ll /etc/neutron/plugin.ini

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

[root@controller ~]# 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

[root@controller ~]# systemctl restart openstack-nova-api.service

[root@controller ~]# systemctl enable neutron-server.service   neutron-linuxbridge-agent.service neutron-dhcp-agent.service   neutron-metadata-agent.service

[root@controller ~]# systemctl start neutron-server.service   neutron-linuxbridge-agent.service neutron-dhcp-agent.service   neutron-metadata-agent.service

[root@controller ~]# systemctl enable neutron-l3-agent.service

[root@controller ~]# systemctl start neutron-l3-agent.service

2、验证

[root@controller ~]# openstack network agent list
