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 = ml2 service_plugins = router auth_strategy = keystone state_path = /var/lib/neutron dhcp_agent_notification = True allow_overlapping_ips = True notify_nova_on_port_status_changes = True notify_nova_on_port_data_changes = True transport_url = rabbit://openstack:password@172.16.100.10 [keystone_authtoken] auth_uri = http://172.16.100.10:5000 auth_url = http://172.16.100.10:35357 memcached_servers = 172.16.100.10:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = neutron password = servicepassword [database] connection = mysql+pymysql://neutron:password@172.16.100.10/neutron [nova] auth_url = http://172.16.100.10:35357 auth_type = password project_domain_name = default user_domain_name = default region_name = RegionOne project_name = service username = nova password = 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,vxlan tenant_network_types = mechanism_drivers = openvswitch,l2population extension_drivers = port_security #注释以下几行 enable_security_group = True firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver enable_ipset = True

5、修改/etc/nova/nova.conf

[DEFAULT] use_neutron = True linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriver firewall_driver = nova.virt.firewall.NoopFirewallDriver [neutron] url = http://172.16.100.10:9696 auth_url = http://172.16.100.10:35357 auth_type = password project_domain_name = default user_domain_name = default region_name = RegionOne project_name = service username = neutron password = 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 = ml2 service_plugins = router auth_strategy = keystone state_path = /var/lib/neutron allow_overlapping_ips = True transport_url = rabbit://openstack:password@172.16.100.10 [keystone_authtoken] auth_uri = http://172.16.100.10:5000 auth_url = http://172.16.100.10:35357 memcached_servers = 172.16.100.10:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = neutron password = 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: add interface_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: add interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver # line 32: uncomment dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq # line 41: uncomment and change enable_isolated_metadata = https://www.it610.com/article/True 5、修改配置文件/etc/neutron/metadata_agent.ini # line 22: uncomment and specify Nova API server nova_metadata_ip = 172.16.100.10 # line 34: uncomment and specify any secret key you like metadata_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,vxlan tenant_network_types = mechanism_drivers = openvswitch,l2population extension_drivers = port_security # line 247: uncomment and add enable_security_group = True firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver # end line: uncomment enable_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; do systemctl start neutron-$service systemctl enable neutron-$service done

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 = ml2 service_plugins = router auth_strategy = keystone state_path = /var/lib/neutron allow_overlapping_ips = True transport_url = rabbit://openstack:password@172.16.100.10[keystone_authtoken] auth_uri = http://172.16.100.10:5000 auth_url = http://172.16.100.10:35357 memcached_servers = 172.16.100.10:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = neutron password = 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,vxlan tenant_network_types = mechanism_drivers = openvswitch,l2population extension_drivers = port_security # line 247: uncomment and add enable_security_group = True firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver # end line: uncomment enable_ipset = True

5、修改/etc/nova/nova.conf

[DEFAULT] use_neutron = True linuxnet_interface_driver = nova.network.linux_net.LinuxOVSInterfaceDriver firewall_driver = nova.virt.firewall.NoopFirewallDriver vif_plugging_is_fatal = True vif_plugging_timeout = 300[neutron] url = http://172.16.100.10:9696 auth_url = http://172.16.100.10:35357 auth_type = password project_domain_name = default user_domain_name = default region_name = RegionOne project_name = service username = neutron password = servicepassword service_metadata_proxy = True metadata_proxy_shared_secret = metadata_secret

6、创建软连接
