一、创建neutron相关数据库、服务凭证和API端点

1.创建neutron数据库，授予合适的访问权限

mysql -uroot -ploongson -e “CREATE DATABASE neutron;”
mysql -uroot -ploongson -e “GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron’@‘localhost’ IDENTIFIED BY ‘loongson’;”
mysql -uroot -ploongson -e “GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron’@‘%’ IDENTIFIED BY ‘loongson’;”

#要创建服务凭证
#以下命令需要输入密码
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

#创建网络服务 API 端点
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
openstack endpoint list

二、neutron相关软件安装与配置

#安装neutron相关软件
yum install -y openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables

#配置服务器组件
cp /etc/neutron/neutron.conf /etc/neutron/neutron.conf.bac
openstack-config --set /etc/neutron/neutron.conf DEFAULT core_plugin ml2
openstack-config --set /etc/neutron/neutron.conf DEFAULT service_plugins router
openstack-config --set /etc/neutron/neutron.conf DEFAULT transport_url rabbit://guest:loongson@10.130.0.31:5672
openstack-config --set /etc/neutron/neutron.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/neutron/neutron.conf DEFAULT notify_nova_on_port_status_changes True
openstack-config --set /etc/neutron/neutron.conf DEFAULT notify_nova_on_port_data_changes True

openstack-config --set /etc/neutron/neutron.conf database connection mysql+pymysql://neutron:loongson@controller:3306/neutron

openstack-config --set /etc/neutron/neutron.conf keystone_authtoken www_authenticate_uri http://controller:5000
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_url http://controller:5000
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken memcached_servers controller:11211
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_type password
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken project_domain_name default
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken user_domain_name default
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken project_name service
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken username neutron
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken password loongson

openstack-config --set /etc/neutron/neutron.conf nova auth_url http://controller:5000
openstack-config --set /etc/neutron/neutron.conf nova auth_type password
openstack-config --set /etc/neutron/neutron.conf nova project_domain_name default
openstack-config --set /etc/neutron/neutron.conf nova user_domain_name default
openstack-config --set /etc/neutron/neutron.conf nova region_name RegionOne
openstack-config --set /etc/neutron/neutron.conf nova project_name service
openstack-config --set /etc/neutron/neutron.conf nova username nova
openstack-config --set /etc/neutron/neutron.conf nova password loongson

openstack-config --set /etc/neutron/neutron.conf oslo_concurrency lock_path /var/lib/neutron/tmp

#配置模块化第 2 层 (ML2) 插件
cp /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugins/ml2/ml2_conf.ini.bac
openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 type_drivers local,flat,vlan,gre,vxlan,geneve
openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 tenant_network_types vxlan
openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 mechanism_drivers linuxbridge
openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 extension_drivers port_security

openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2_type_flat flat_networks provider

openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2_type_vxlan vni_ranges 1:1000

#注意网卡名称需要根据实际情况修改
#配置 Linux 网桥代理
cp /etc/neutron/plugins/ml2/linuxbridge_agent.ini /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bac
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini vxlan enable_vxlan true
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini vxlan local_ip 10.130.0.31
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini vxlan l2_population true

openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup enable_security_group false
#openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup firewall_driver neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup firewall_driver iptables

#请根据实际情况修改网卡名称
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini linux_bridge physical_interface_mappings provider:enp0s3f0

#配置 DHCP 代理
cp /etc/neutron/dhcp_agent.ini /etc/neutron/dhcp_agent.ini.bac
openstack-config --set /etc/neutron/dhcp_agent.ini DEFAULT interface_driver linuxbridge
openstack-config --set /etc/neutron/dhcp_agent.ini DEFAULT dhcp_driver neutron.agent.linux.dhcp.Dnsmasq
openstack-config --set /etc/neutron/dhcp_agent.ini DEFAULT enable_isolated_metadata true

#配置元数据代理
cp /etc/neutron/metadata_agent.ini /etc/neutron/metadata_agent.ini.bac
openstack-config --set /etc/neutron/metadata_agent.ini DEFAULT nova_metadata_host controller
openstack-config --set /etc/neutron/metadata_agent.ini DEFAULT metadata_proxy_shared_secret loongson

三、配置 Compute 服务以使用 Networking 服务

#安装计算相关网络服务
yum install -y openstack-neutron-linuxbridge ebtables ipset

#完成安装
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
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
systemctl restart openstack-nova-api.service

#使能控制节点网络服务
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

systemctl status neutron-server.service
neutron-linuxbridge-agent.service neutron-dhcp-agent.service
neutron-metadata-agent.service
