Centos7.4安装openstack（queens）详细安装部署（五）－网络服务（neutron）安装
一、创库授权
1.1.、（控制节点）配置数据库
mysql -u root -pADMIN_PASS
1.2、创建数据库并配置权限
CREATE DATABASE neutron; GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'ADMIN_PASS'; GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'ADMIN_PASS';
1.3、控制节点）创建认证信息
openstack user create --domain default --password ADMIN_PASS neutron openstack role add --project service --user neutron admin openstack service create --name neutron --description "OpenStack Networking" network openstack endpoint create --region RegionOne network public http://controller:9696 openstack endpoint create --region RegionOne network internal http://controller:9696 openstack endpoint create --region RegionOne network admin http://controller:9696

[vxlan] enable_vxlan = true local_ip = 172.16.1.11 l2_population = true ... [securitygroup] enable_security_group = true firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
1.5、确认内核支持网桥filters并作如下设置，编辑/etc/sysctl.conf增加以下内容
/etc/sysctl.conf net.bridge.bridge-nf-call-iptables=1 net.bridge.bridge-nf-call-ip6tables=1
1.6、载入br_netfilter模块
modprobe br_netfilter
从配置文件加载内核参数
sysctl -p

/etc/neutron/metadata_agent.ini [DEFAULT] nova_metadata_host = controller metadata_proxy_shared_secret = ADMIN_PASS
2.0、编辑文件/etc/nova/nova.conf配置计算服务使用网络服务
/etc/nova/nova.conf [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 = ADMIN_PASS service_metadata_proxy = true metadata_proxy_shared_secret = ADMIN_PASS
三、（控制节点）完成安装，导入数据库表，并启动服务
1.1、创建链接文件
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
1.2、导入数据库结构
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
1.3、重启计算服务，设置网络服务的开机自启动，并启动网络服务
systemctl restart openstack-nova-api.service systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service systemctl start neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service systemctl enable neutron-l3-agent.service systemctl start neutron-l3-agent.service
