# vim /etc/neutron/neutron.conf[database]----配置数据库访问[用户名:密码@控制节点]#connection = sqlite:////var/lib/neutron/neutron.sqliteconnection = mysql+pymysql://neutron:neutron@192.168.30.145/neutron[DEFAULT]----启用ML2插件、路由器服务和overlapping IP addressescore_plugin = ml2service_plugins = routerallow_overlapping_ips = true [DEFAULT]----配置 RabbitMQ 消息队列访问[用户名:密码@控制节点]transport_url = rabbit://openstack:openstack@192.168.30.145[DEFAULT]----配置认证服务访问auth_strategy = keystone[keystone_authtoken]----配置认证服务访问auth_uri = http://192.168.30.145:5000auth_url = http://192.168.30.145:35357memcached_servers = 192.168.30.145:11211auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultproject_name = serviceusername = neutronpassword = neutron [DEFAULT]----配置网络服务来通知计算节点的网络拓扑变化notify_nova_on_port_status_changes = truenotify_nova_on_port_data_changes = true[nova]----配置网络服务来通知计算节点的网络拓扑变化auth_url = http://192.168.30.145:35357auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultregion_name = RegionOneproject_name = serviceusername = novapassword = nova# grep ^[a-z] /etc/neutron/neutron.conf auth_strategy = keystonecore_plugin = ml2service_plugins = routerallow_overlapping_ips = truenotify_nova_on_port_status_changes = truenotify_nova_on_port_data_changes = truetransport_url = rabbit://openstack:openstack@192.168.30.145root_helper = sudo /usr/bin/neutron-rootwrap /etc/neutron/rootwrap.confconnection = mysql+pymysql://neutron:neutron@192.168.30.145/neutronauth_uri = http://192.168.30.145:5000auth_url = http://192.168.30.145:35357memcached_servers = 192.168.30.145:11211auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultproject_name = serviceusername = neutronpassword = neutronregion_name = RegionOneauth_url = http://192.168.30.145:35357auth_type = passwordpassword = novaproject_domain_name = defaultproject_name = serviceuser_domain_name = defaultusername = nova
c.配置 Modular Layer 2 (ML2) 插件
ML2插件使用Linuxbridge机制来为实例创建layer－2虚拟网络基础设施
# vim /etc/neutron/plugins/ml2/ml2_conf.ini[ml2]----启用flat，VLAN以及VXLAN网络type_drivers = flat,vlan,vxlan[ml2]----启用VXLAN私有网络tenant_network_types = vxlan[ml2]----启用Linuxbridge和layer－2机制mechanism_drivers = linuxbridge,l2population[ml2]----启用端口安全扩展驱动extension_drivers = port_security [ml2_type_flat]----配置公共虚拟网络为flat网络flat_networks = provider[ml2_type_vxlan]----为私有网络配置VXLAN网络识别的网络范围vni_ranges = 1:1000[securitygroup]----启用 ipset 增加安全组规则的高效性enable_ipset = true # grep ^[a-z] /etc/neutron/plugins/ml2/ml2_conf.initype_drivers = flat,vlan,vxlantenant_network_types = vxlanmechanism_drivers = linuxbridge,l2populationextension_drivers = port_securityflat_networks = providervni_ranges = 1:1000enable_ipset = true
注:Linuxbridge代理只支持VXLAN覆盖网络
d.配置Linuxbridge代理
Linuxbridge代理为实例建立layer－2虚拟网络并且处理安全组规则
# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini[linux_bridge]----对应公共虚拟网络和公共物理网络接口physical_interface_mappings = provider:ens33[vxlan]----启用VXLAN覆盖网络，配置覆盖网络的物理网络接口的IP地址，并启用layer－2 populationenable_vxlan = truelocal_ip = 192.168.30.145l2_population = true[securitygroup]----启用安全组并配置防火墙服务enable_security_group = truefirewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver# grep ^[a-z] /etc/neutron/plugins/ml2/linuxbridge_agent.iniphysical_interface_mappings = provider:ens33firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriverenable_security_group = trueenable_vxlan = truelocal_ip = 192.168.30.145l2_population = true
e.配置layer－3代理
Layer-3代理为私有虚拟网络提供路由和NAT服务
# vim /etc/neutron/l3_agent.ini[DEFAULT]----配置Linuxbridge接口驱动和外部网络网桥interface_driver = linuxbridge# grep ^[a-z] /etc/neutron/l3_agent.iniinterface_driver = linuxbridge
f.配置DHCP代理
DHCP代理为虚拟网络提供DHCP服务
# vim /etc/neutron/dhcp_agent.ini [DEFAULT]----配置Linuxbridge驱动接口，DHCP驱动并启用隔离元数据interface_driver = linuxbridgedhcp_driver = neutron.agent.linux.dhcp.Dnsmasqenable_isolated_metadata = true# grep ^[a-z] /etc/neutron/dhcp_agent.ini interface_driver = linuxbridgedhcp_driver = neutron.agent.linux.dhcp.Dnsmasqenable_isolated_metadata = true
g.配置元数据代理----负责提供配置信息
# vim /etc/neutron/metadata_agent.ini[DEFAULT]----配置元数据主机以及共享密码nova_metadata_ip = 192.168.30.145metadata_proxy_shared_secret = qaz123# grep ^[a-z] /etc/neutron/metadata_agent.ini nova_metadata_ip = 192.168.30.145metadata_proxy_shared_secret = qaz123
5.在控制节点上为计算节点配置网络服务
# vim /etc/nova/nova.conf[neutron]----配置访问参数，启用元数据代理并设置密码url = http://192.168.30.145:9696auth_url = http://192.168.30.145:35357auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultregion_name = RegionOneproject_name = serviceusername = neutronpassword = neutronservice_metadata_proxy = truemetadata_proxy_shared_secret = qaz123# grep ^[a-z] /etc/nova/nova.conf
6.完成安装
a.同步数据库
# 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......OK
注:数据库的同步发生在 Networking 之后，因为脚本需要完成服务器和插件的配置文件
b.重启计算 API 服务
# service nova-api restart
c.重启 Networking 服务
对于两种网络类型:
# service neutron-server restart# service neutron-linuxbridge-agent restart# service neutron-dhcp-agent restart# service neutron-metadata-agent restart
对于网络类型 2 ，还需重启 L3 服务:
# service neutron-l3-agent restart
d.确认启动与否
# service nova-api status# service neutron-server status# service neutron-linuxbridge-agent status# service neutron-dhcp-agent status# service neutron-metadata-agent status# service neutron-l3-agent status
7.配置 Compute Node 的 Neutron 网络服务
# apt -y install neutron-linuxbridge-agent# vim /etc/neutron/neutron.conf[database]----计算节点不直接访问数据库#connection = sqlite:////var/lib/neutron/neutron.sqlite[DEFAULT]----配置 RabbitMQ 消息队列访问[用户名:密码@控制节点]transport_url = rabbit://openstack:openstack@192.168.30.145[DEFAULT]----配置认证服务访问auth_strategy = keystone[keystone_authtoken]----配置认证服务访问auth_uri = http://192.168.30.145:5000auth_url = http://192.168.30.145:35357memcached_servers = 192.168.30.145:11211auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultproject_name = serviceusername = neutronpassword = neutron# grep ^[a-z] /etc/neutron/neutron.conf auth_strategy = keystonecore_plugin = ml2transport_url = rabbit://openstack:openstack@192.168.30.145root_helper = sudo /usr/bin/neutron-rootwrap /etc/neutron/rootwrap.confauth_uri = http://192.168.30.145:5000auth_url = http://192.168.30.145:35357memcached_servers = 192.168.30.145:11211auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultproject_name = serviceusername = neutronpassword = neutron
8.为计算节点配置网络服务
# vim /etc/nova/nova.conf[neutron]----配置访问参数url = http://192.168.30.145:9696auth_url = http://192.168.30.145:35357auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultregion_name = RegionOneproject_name = serviceusername = neutronpassword = neutron# grep ^[a-z] /etc/nova/nova.conf
9.完成安装
a.重启计算服务:
# service nova-compute restart# service nova-compute status
b.重启Linuxbridge代理:
# service neutron-linuxbridge-agent restart# service neutron-linuxbridge-agent status
10.在计算节点上配置网络类型2
