本篇文章本应该是在周二的时候更新的，当时并没有更新，主要是在考虑怎样做才能把这个公众号给做好，给大家提供更好的帮助。思考了一天，仍没有什么好的想法。如果大家有好的建议，好的想法可在文章底部留言。
安装neutron
[root@compute ~]# yum install -y openstack-neutronopenstack-neutron-linuxbridge ebtables ipset
配置neutron
控制节点和计算节点的配置一样，可以直接从控制节点拷贝。
[root@controller ~]# scp /etc/neutron/neutron.conf 192.168.1.12:/etc/neutron/[root@controller ~]# scp /etc/neutron/plugins/ml2/linuxbridge_agent.ini192.168.1.12:/etc/neutron/plugins/ml2/[root@controller ~]# scp /etc/neutron/plugins/ml2/ml2_conf.ini192.168.1.12:/etc/neutron/plugins/ml2[root@compute ~]# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini/etc/neutron/plugin.ini配置nova

[root@compute ~]# systemctl restart openstack-nova-compute[root@compute ~]# systemctl enable neutron-linuxbridge-agent.service[root@compute ~]# systemctl start neutron-linuxbridge-agent.service查看验证
