openstack部署neutron

controller

　　1.创建数据库并设置权限

　　mysql -u root -p0330

　　CREATE DATABASE neutron;

　　GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \ IDENTIFIED BY 'NEUTRON_DBPASS';

　 GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \ IDENTIFIED BY 'NEUTRON_DBPASS';

　　2.创建openstack用户

　　source openrc

　　openstack user create --domain default --password=neutron neutron

　　3.给neutron设置成admin角色

　　openstack role add --project service --user neutron admin

　　4.创建服务

　　openstack service create --name neutron \ --description "OpenStack Networking" network

　　5.创建服务端点

　　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

　　6.安装服务

　　yum install openstack-neutron openstack-neutron-ml2 openvswitch openstack-neutron-openvswitch ebtables -y

 　　7.编辑配置文件（第三块网卡不配置ip）

　　cp /etc/neutron/neutron.conf /etc/neutron/neutron.conf.bak

　　cp /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugins/ml2/ml2_conf.ini.bak

　　cp /etc/neutron/plugins/ml2/openvswitch_agent.ini /etc/neutron/plugins/ml2/openvswitch_agent.ini.bak
　　cp /etc/neutron/l3_agent.ini /etc/neutron/l3_agent.ini.bak
　　cp/etc/neutron/dhcp_agent.ini /etc/neutron/dhcp_agent.ini.bak

　　cp /etc/neutron/metadata_agent.ini /etc/neutron/metadata_agent.ini.bak

user_domain_name = default

vim /etc/nova/nova.conf

　　9.创建软链接

　　ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

　　10.同步数据库

　　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

　　11.重启服务

　　systemctl restart openstack-nova-api.service、

　　systemctl enable neutron-server.service neutron-dhcp-agent.service openvswitch neutron-openvswitch-agent neutron-metadata-agent.service

　　 systemctl start neutron-server.service neutron-dhcp-agent.service openvswitch neutron-openvswitch-agent neutron-metadata-agent.service

　　  12.创建网桥

　　 ovs-vsctl add-br br-ex

　　ovs-vsctl add-port br-ex eth38

　　 ovs-vsctl show

　　  13.开启l3-agent

　　  systemctl enable neutron-l3-agent.service

　　  systemctl enable neutron-l3-agent.service

　　14.查看neutron服务状态

　　openstack  neutron service list

　　　　3.编辑nova配置文件

auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne

username = neutron
password = NEUTRON_PASS

vim /etc/nova/nova.conf

　　　　4.重启服务

　　　　systemctl restart openstack-nova-compute.service

　　　　systemctl enable openvswitch neutron-openvswitch-agent

　　　　  systemctl start openvswitch neutron-openvswitch-agent

　　　　5.到控制节点查看

　　　　openstack  neutron service list

　　以上是neutron的安装，如果需要的话也可以在storage节点上部署neutron服务。
