1.創(chuàng)建neutron數(shù)據(jù)庫
[root@localhost ~]# MySQL -uroot -pdevops

2.創(chuàng)建neutron用戶和項目
[root@localhost ~]# source /root/admin-openrc
[root@localhost ~]# openstack user create --domain default neutron --password devops
[root@localhost ~]# openstack role add --project service --user neutron admin
[root@localhost ~]# openstack service create --name neutron --description "OpenStack Networking" network

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

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

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

3.安裝neuton服務和修改配置文件
[root@localhost ~]# yum -y install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables
[root@controller ~]# cp /etc/neutron/neutron.conf /etc/neutron/neutron.conf.bak
[root@controller ~]# >/etc/neutron/neutron.conf
[root@controller ~]# cat /etc/neutron/neutron.conf
[DEFAULT]
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = True
auth_strategy = keystone
transport_url = rabbit://openstack:devops@controller
notify_nova_on_port_status_changes = True
notify_nova_on_port_data_changes = True
[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 = nova
password = devops
[database]
connection = mysql+pymysql://neutron:devops@controller/neutron
[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 = devops
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
[root@controller ~]# cat /etc/neutron/plugins/ml2/ml2_conf.ini | grep -v "^#" | grep -v "^$"
[DEFAULT]
[ml2]
type_drivers = flat,vlan,vxlan
mechanism_drivers = linuxbridge,l2population
extension_drivers = port_security
tenant_network_types = vxlan
path_mtu = 1500
[ml2_type_flat]
flat_networks = provider
[ml2_type_geneve]
[ml2_type_gre]
[ml2_type_vlan]
[ml2_type_vxlan]
vni_ranges = 1:1000
[securitygroup]
enable_ipset = True
[root@controller ~]# cat /etc/neutron/plugins/ml2/linuxbridge_agent.ini | grep -v "^#" | grep -v "^$"
[DEFAULT]
debug = false
[agent]
prevent_arp_spoofing = True
[linux_bridge]
physical_interface_mappings = provider:ens33
[securitygroup]
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
[vxlan]

目前創(chuàng)新互聯(lián)建站已為千余家的企業(yè)提供了網(wǎng)站建設、域名、虛擬主機、網(wǎng)站托管、服務器托管、企業(yè)網(wǎng)站設計、南召網(wǎng)站維護等服務，公司將堅持客戶導向、應用為本的策略，正道將秉承"和諧、參與、激情"的文化，與客戶和合作伙伴齊心協(xié)力一起成長，共同發(fā)展。

[root@controller ~]# cat /etc/neutron/l3_agent.ini | grep -v "^#" | grep -v "^$"
[DEFAULT]
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
external_network_bridge =
debug = false
[agent]
[ovs]

[root@controller ~]# cat /etc/neutron/dhcp_agent.ini | grep -v "^#" | grep -v "^$"
[DEFAULT]
interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
dhcp_driver = neutron.agent.linux.dhcp.DNSmasq
enable_isolated_metadata = True
verbose = True
debug = false
[agent]
[ovs]
重新配置/etc/nova/nova.conf，配置這步的目的是讓compute節(jié)點能使用上neutron網(wǎng)絡
[neutron]
url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = devops
service_metadata_proxy = True
metadata_proxy_shared_secret = devops
將dhcp-option-force=26,1450寫入/etc/neutron/dnsmasq-neutron.conf
# echo "dhcp-option-force=26,1450" >/etc/neutron/dnsmasq-neutron.conf
[root@controller ~]# cat /etc/neutron/metadata_agent.ini | grep -v "^#" | grep -v "^$"
[DEFAULT]
nova_metadata_ip = controller
metadata_proxy_shared_secret = devops
metadata_workers = 4
verbose = True
debug = false
nova_metadata_protocol = http
[agent]
[cache]
4.創(chuàng)建連接并創(chuàng)建keystone用戶
[root@localhost ~]# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
5.更新數(shù)據(jù)庫
[root@localhost ~]# 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@localhost ~]# systemctl restart openstack-nova-api.service
[root@controller ~]# systemctl status openstack-nova-api.service
6.啟動服務
[root@localhost ~]# systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
[root@localhost ~]# systemctl start neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
啟動neutron-l3-agent.service并設置開機啟動
# systemctl enable neutron-l3-agent.service
**# systemctl restart neutron-l3-agent.service
# systemctl status neutron-l3-agent.service
[root@controller ~]# neutron ext-list
[root@localhost ~]# neutron agent-list

7.查看注冊信息
[root@localhost ~]# openstack endpoint list

所有的配置文件在百度云盤中：

復制這段內(nèi)容后打開百度網(wǎng)盤手機App，操作更方便哦
