本文主要是介绍openstack Queens版本在centos7.1，最小化安装(安装neutron(控制节点)），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
Hosts
10.0.2.111 con01controller
10.0.2.112 com01compute1
确保这网络OK
ping -c 4 openstack.org
ping -c 4 compute1
ping -c 4 controller
在数据库中创建neutron库和用户并授权
[root@con01~]# mysql -u root -ptest.2018

[neutron]
url = http://controller:9696
auth_url= http://controller:35357
auth_type= password
project_domain_name= default
user_domain_name= default
region_name= RegionOne
project_name= service
username= neutron
password= test.2018
service_metadata_proxy= true
metadata_proxy_shared_secret= METADATA_SECRET
**********************************************************************
完成安装
1. # ln -s/etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
2. 初始化数据库
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-api
[root@controller~]# systemctl restart openstack-nova-api.service
启动服务
# systemctl enable neutron-server.service \
neutron-linuxbridge-agent.serviceneutron-dhcp-agent.service \
neutron-metadata-agent.service
# systemctl restart neutron-server.service \
neutron-linuxbridge-agent.serviceneutron-dhcp-agent.service \
neutron-metadata-agent.service
