一、Controller配置
1、安装软件

# yum --enablerepo=centos-openstack-ocata,epel -y install openstack-neutron openstack-neutron-ml2

2、修改配置文件/etc/neutron/neutron.conf

[DEFAULT]core_plugin = ml2service_plugins = routerauth_strategy = keystonestate_path = /var/lib/neutrondhcp_agent_notification = Trueallow_overlapping_ips = Truenotify_nova_on_port_status_changes = Truenotify_nova_on_port_data_changes = Truetransport_url = rabbit://openstack:password@172.16.100.10[keystone_authtoken]auth_uri = http://172.16.100.10:5000auth_url = http://172.16.100.10:35357memcached_servers = 172.16.100.10:11211auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultproject_name = serviceusername = neutronpassword = servicepassword[database]connection = mysql+pymysql://neutron:password@172.16.100.10/neutron[nova]auth_url = http://172.16.100.10:35357auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultregion_name = RegionOneproject_name = serviceusername = novapassword = servicepassword[oslo_concurrency]lock_path = $state_path/tmp

3、修改权限

# chmod 640 /etc/neutron/neutron.conf # chgrp neutron /etc/neutron/neutron.conf 

4、修改配置文件/etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]type_drivers = flat,vlan,gre,vxlantenant_network_types =mechanism_drivers = openvswitch,l2populationextension_drivers = port_security#注释以下几行enable_security_group = Truefirewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriverenable_ipset = True

5、修改/etc/nova/nova.conf

[DEFAULT]use_neutron = Truelinuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriverfirewall_driver = nova.virt.firewall.NoopFirewallDriver[neutron]url = http://172.16.100.10:9696auth_url = http://172.16.100.10:35357auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultregion_name = RegionOneproject_name = serviceusername = neutronpassword = servicepassword

6、创建链接

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

7、同步数据库

# su -s /bin/bash neutron -c "neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugin.ini upgrade head" 

8、重启服务

# systemctl start neutron-server # systemctl enable neutron-server # systemctl restart openstack-nova-api

二、网络节点配置
1、安装软件

# yum --enablerepo=centos-openstack-ocata,epel -y install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch

2、修改配置文件/etc/neutron/neutron.conf

[DEFAULT]core_plugin = ml2service_plugins = routerauth_strategy = keystonestate_path = /var/lib/neutronallow_overlapping_ips = Truetransport_url = rabbit://openstack:password@172.16.100.10[keystone_authtoken]auth_uri = http://172.16.100.10:5000auth_url = http://172.16.100.10:35357memcached_servers = 172.16.100.10:11211auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultproject_name = serviceusername = neutronpassword = servicepassword[oslo_concurrency]lock_path = $state_path/lock

2、修改权限

# chmod 640 /etc/neutron/neutron.conf # chgrp neutron /etc/neutron/neutron.conf 

3、修改配置文件/etc/neutron/l3_agent.ini

# line 17: addinterface_driver = neutron.agent.linux.interface.OVSInterfaceDriver# line 100: add ( it's OK with no value (set later if need) )external_network_bridge =

4、修改配置文件/etc/neutron/dhcp_agent.ini

# line 17: addinterface_driver = neutron.agent.linux.interface.OVSInterfaceDriver# line 32: uncommentdhcp_driver = neutron.agent.linux.dhcp.Dnsmasq# line 41: uncomment and changeenable_isolated_metadata = True5、修改配置文件/etc/neutron/metadata_agent.ini# line 22: uncomment and specify Nova API servernova_metadata_ip = 172.16.100.10# line 34: uncomment and specify any secret key you likemetadata_proxy_shared_secret = metadata_secret

6、修改配置文件/etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]type_drivers = flat,vlan,gre,vxlantenant_network_types =mechanism_drivers = openvswitch,l2populationextension_drivers = port_security# line 247: uncomment and addenable_security_group = Truefirewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver# end line: uncommentenable_ipset = True

7、创建链接

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

8、重启服务

# systemctl start openvswitch # systemctl enable openvswitch 

9、创建网桥

# ovs-vsctl add-br br-int 

10、重启服务

# for service in dhcp-agent l3-agent metadata-agent openvswitch-agent; dosystemctl start neutron-$servicesystemctl enable neutron-$servicedone

三、计算节点配置
1、安装软件

# yum --enablerepo=centos-openstack-ocata,epel -y install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch

2、修改配置文件/etc/neutron/neutron.conf

[DEFAULT]core_plugin = ml2service_plugins = routerauth_strategy = keystonestate_path = /var/lib/neutronallow_overlapping_ips = Truetransport_url = rabbit://openstack:password@172.16.100.10[keystone_authtoken]auth_uri = http://172.16.100.10:5000auth_url = http://172.16.100.10:35357memcached_servers = 172.16.100.10:11211auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultproject_name = serviceusername = neutronpassword = servicepassword[oslo_concurrency]lock_path = $state_path/lock

3、修改权限

# chmod 640 /etc/neutron/neutron.conf # chgrp neutron /etc/neutron/neutron.conf 

4、修改/etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]type_drivers = flat,vlan,gre,vxlantenant_network_types =mechanism_drivers = openvswitch,l2populationextension_drivers = port_security# line 247: uncomment and addenable_security_group = Truefirewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver# end line: uncommentenable_ipset = True

5、修改/etc/nova/nova.conf

[DEFAULT]use_neutron = Truelinuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriverfirewall_driver = nova.virt.firewall.NoopFirewallDrivervif_plugging_is_fatal = Truevif_plugging_timeout = 300[neutron]url = http://172.16.100.10:9696auth_url = http://172.16.100.10:35357auth_type = passwordproject_domain_name = defaultuser_domain_name = defaultregion_name = RegionOneproject_name = serviceusername = neutronpassword = servicepasswordservice_metadata_proxy = Truemetadata_proxy_shared_secret = metadata_secret

6、创建软连接

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

7、启动服务

# systemctl start openvswitch # systemctl enable openvswitch 

8、创建网桥

# ovs-vsctl add-br br-int

9、重启服务并设置开机启动

# systemctl restart openstack-nova-compute # systemctl start neutron-openvswitch-agent # systemctl enable neutron-openvswitch-agent
