七：OPENSTACK Queens部署网络服务neutron

Posted 2021-04-24 MisterChen

备注：在控制节点操作

• 创建neutron数据库和用户

[root@controller ~]# mysql -uroot -p

create database neutron;

GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY '123456';

GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY '123456';

• 增加neutron用户

[root@controller ~]# openstack user create --domain default --password-prompt neutron

• 将neutron用户添加server和damin

[root@controller ~]# openstack role add --project service --user neutron admin

[root@controller ~]# openstack service create --name neutron --description "OpenStack Networking" network

[root@controller ~]# openstack endpoint create --region RegionOne network public http://controller:9696

[root@controller ~]# openstack endpoint create --region RegionOne network internal http://controller:9696

[root@controller ~]# openstack endpoint create --region RegionOne network admin http://controller:9696

• 安装网络服务包

[root@controller ~]# yum install -y openstack-neutron openstack-neutron-ml2   openstack-neutron-linuxbridge ebtables

我这里先使用比较简单的公共网络模式（provider network）

• 编辑配置文件neutron.conf 

[root@controller ~]# vim /etc/neutron/neutron.conf 

[database]

connection = mysql+pymysql://neutron:123456@controller/neutron

[DEFAULT]

core_plugin = ml2

service_plugins =

transport_url = rabbit://openstack:123456@controller

auth_strategy = keystone

notify_nova_on_port_status_changes = true

notify_nova_on_port_data_changes = true

[keystone_authtoken]

auth_uri = http://controller:5000

auth_url = http://controller:35357

memcached_servers = controller:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = neutron

password = 123456

[nova]

auth_url = http://controller:35357

auth_type = password

project_domain_name = default

user_domain_name = default

region_name = RegionOne

project_name = service

username = nova

password = 123456

[oslo_concurrency]

lock_path = /var/lib/neutron/tmp

• 编辑配置文件ml2_conf.ini

[root@controller ~]# vim /etc/neutron/plugins/ml2/ml2_conf.ini

[ml2_type_flat]

flat_networks = provider

[ml2]

type_drivers = flat,vlan

tenant_network_types =

mechanism_drivers = linuxbridge

extension_drivers = port_security

• 编辑配置文件linuxbridge_agent.ini 

[root@controller ~]# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini 

[vxlan]

enable_vxlan = false

[linux_bridge]

physical_interface_mappings = provider:ens160

[securitygroup]

enable_security_group = true

firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

• 编辑配置文件00-system.conf ，修改为1

[root@controller ~]# vim /usr/lib/sysctl.d/00-system.conf 

net.bridge.bridge-nf-call-ip6tables = 1

net.bridge.bridge-nf-call-iptables = 1

• 编辑配置文件dhcp_agent.ini

[root@controller ~]# vim /etc/neutron/dhcp_agent.ini

[DEFAULT]

interface_driver = linuxbridge

dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq

enable_isolated_metadata = true

• 编辑配置文件metadata_agent.ini

[root@controller ~]# vim /etc/neutron/metadata_agent.ini

[DEFAULT]

nova_metadata_host = controller

metadata_proxy_shared_secret = 123456

• 编辑配置文件nova.conf

[root@controller ~]# vim /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 = 123456

service_metadata_proxy = true

metadata_proxy_shared_secret = 123456

• 做软连接

[root@controller ~]# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

• 同步数据库

[root@controller ~]# 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

• 重新启动nova-api服务

[root@controller ~]# systemctl restart openstack-nova-api.service

• 启动网络服务

[root@controller ~]# systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service   neutron-metadata-agent.service

[root@controller ~]# systemctl start neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
