修改配置文件（编辑配置文件之前先cp一份）
#vim /etc/neutron/neutron.conf
配置文件查看neutron配置文件neutron.conf
#vim /etc/neutron/plugins/ml2/ml2_conf.ini
配置文件查看neutron配置文件ml2_conf.ini
#vim /etc/neutron/plugins/ml2/openvswitch_agent.ini
配置文件查看neutron配置文件openvswitch_agent.ini
#vim /etc/neutron/l3_agent.ini
配置文件查看neutron配置文件l3_agent.ini
#vim /etc/neutron/metadata_agent.ini
配置文件查看neutron配置文件metadata_agent.ini
#vim /etc/neutron/dhcp_agent.ini
配置文件查看neutron配置文件dhcp_agent.ini
修改配置nova配置文件
#vim /etc/nova/nova.conf
把里面neutron下相关项目取消注释（具体参考nova配置文件）
创建软链接
# ln -s /etc/neutron/plugins/ml2/ml2_conf.init /etc/neutron/plugin.ini
导入neutron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
重启nova服务
#systemctl restart openstack-nova-api
启动服务
#systemctl start neutron-server neutron-dhcp-agent openvswitch neutron-openvswitch-agent neutron-metadata-agent
设置开机自启
#systemctl enable neutron-server neutron-dhcp-agent openvswitch neutron-openvswitch-agent neutron-metadata-agent
创建网桥
#ovs-vsctl add-br br-ex
#ovs-vsctl add-port br-ex ens38
启动neutron-l3-agent
#systemctl start neutron-l3-agent.service
设置开机自启
#systemctl enable neutron-l3-agent.service
计算节点
下载软件
#yum -y install openstack-neutron-openvswitch ebtables ipset
修改配置文件（配置文件cp一份在修改）
#vim /etc/neutron/neutron.conf
配置文件查看neutron配置文件neutron.conf
#vim /etc/neutron/plugins/ml2/openvswitch_agent.ini
配置文件查看neutron配置文件openvswitch_agent.ini
修改nova配置文件
#vim /etc/nova/nova.conf
打开neutron下的注释（最后两个注释掉）具体参考nova配置文件
重启nova服务
#systemctl restart openstack-nova-compute
启动服务
#systemctl start openvswitch neutron-openvswitch-agent
#systemctl enable openvswitch neutron-openvswitch-agent
