在计算节点上，通过设置nova与neutron结合，在创建虚拟机实例的时候， neutron-linuxbridge通过控制节点调度虚拟网络获得对应子网网络。 1）在computer1、2节点安装相关软件包 ``` yum install openstack-neutron-linuxbridge ebtables ipset -y ``` 2） 在computer1、2节点配置neutron.conf ``` cp /etc/neutron/neutron.conf /etc/neutron/neutron.conf.bak >/etc/neutron/neutron.conf openstack-config --set /etc/neutron/neutron.conf DEFAULT debug False openstack-config --set /etc/neutron/neutron.conf DEFAULT verbose True openstack-config --set /etc/neutron/neutron.conf DEFAULT rpc_backend rabbit openstack-config --set /etc/neutron/neutron.conf DEFAULT auth_strategy keystone openstack-config --set /etc/neutron/neutron.conf DEFAULT rpc_response_timeout 180 openstack-config --set /etc/neutron/neutron.conf DEFAULT bind_host compute1 openstack-config --set /etc/neutron/neutron.conf DEFAULT dhcp_lease_duration 600 openstack-config --set /etc/neutron/neutron.conf DEFAULT global_physnet_mtu 1500 openstack-config --set /etc/neutron/neutron.conf DEFAULT advertise_mtu True openstack-config --set /etc/neutron/neutron.conf DEFAULT dhcp_agents_per_network 2 openstack-config --set /etc/neutron/neutron.conf DEFAULT control_exchange neutron openstack-config --set /etc/neutron/neutron.conf DEFAULT nova_url http://yjscloud.com:8774/v2 openstack-config --set /etc/neutron/neutron.conf agent root_helper sudo openstack-config --set /etc/neutron/neutron.conf agent report_interval 10 openstack-config --set /etc/neutron/neutron.conf oslo_messaging_rabbit rabbit_hosts controller1:5672,controller2:5672,controller3:5672 openstack-config --set /etc/neutron/neutron.conf oslo_messaging_rabbit rabbit_userid openstack openstack-config --set /etc/neutron/neutron.conf oslo_messaging_rabbit rabbit_password yjscloud openstack-config --set /etc/neutron/neutron.conf oslo_messaging_rabbit rabbit_use_ssl False openstack-config --set /etc/neutron/neutron.conf oslo_messaging_rabbit rabbit_ha_queues True openstack-config --set /etc/neutron/neutron.conf oslo_messaging_rabbit rabbit_retry_interval 1 openstack-config --set /etc/neutron/neutron.conf oslo_messaging_rabbit rabbit_retry_backoff 2 openstack-config --set /etc/neutron/neutron.conf oslo_messaging_rabbit rabbit_max_retries 0 openstack-config --set /etc/neutron/neutron.conf oslo_messaging_rabbit amqp_durable_queues False openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_uri http://yjscloud.com:5000 openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_url http://yjscloud.com:35357 openstack-config --set /etc/neutron/neutron.conf keystone_authtoken memcached_servers controller1:11211,controller2:11211,controller3:11211 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 yjscloud openstack-config --set /etc/neutron/neutron.conf oslo_concurrency lock_path /var/lib/neutron/tmp ``` ``` scp -p /etc/neutron/neutron.conf compute2:/etc/neutron/neutron.conf ``` 注意修改节点名称 3）在computer1、2节点配置`/etc/neutron/plugins/ml2/linuxbridge_agent.ini` ``` openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini linux_bridge physical_interface_mappings provider:ens160 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 10.2.2.153 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 True openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup firewall_driver neutron.agent.linux.iptables_firewall.IptablesFirewallDriver ``` 4）在computer1、2节点配置nova.conf设置nova跟neutron结合 ``` openstack-config --set /etc/nova/nova.conf neutron url http://yjscloud.com:9696 openstack-config --set /etc/nova/nova.conf neutron auth_url http://yjscloud.com:35357 openstack-config --set /etc/nova/nova.conf neutron auth_type password openstack-config --set /etc/nova/nova.conf neutron project_domain_name default openstack-config --set /etc/nova/nova.conf neutron user_domain_name default openstack-config --set /etc/nova/nova.conf neutron region_name RegionOne openstack-config --set /etc/nova/nova.conf neutron project_name service openstack-config --set /etc/nova/nova.conf neutron username neutron openstack-config --set /etc/nova/nova.conf neutron password yjscloud ``` 5）在computer1、2节点重启和enable相关服务 ``` systemctl restart libvirtd.service openstack-nova-compute.service systemctl enable neutron-linuxbridge-agent.service && systemctl restart neutron-linuxbridge-agent.service systemctl status openstack-nova-compute.service neutron-linuxbridge-agent.service ```
