openstack搭建之-neutron配置（11）

时间：2022-08-13 20:31:17

 

一、base节点设置

mysql -u root -proot

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';

 

二、 ctrl节点设置

#运行环境变量

. admin-openrc

 

#创建neutron用户并添加角色

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

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

 

#创建neutron服务并设置endpoint

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

openstack endpoint create --region RegionOne network public http://ctrl.test.com:9696

openstack endpoint create --region RegionOne network internal http://ctrl.test.com:9696

openstack endpoint create --region RegionOne network admin http://ctrl.test.com:9696

 

#安装neutron软件

yum install \

openstack-neutron \

openstack-neutron-ml2 \

openstack-neutron-linuxbridge \

ebtables -y

 

#编辑neutron配置文件

vim /etc/neutron/neutron.conf

[database] connection = mysql+pymysql://neutron:NEUTRON_DBPASS@base.test.com/neutron [DEFAULT] core_plugin = ml2 service_plugins = #service_plugins = router #allow_overlapping_ips = true transport_url = rabbit://openstack:RABBIT_PASS@base.test.com auth_strategy = keystone notify_nova_on_port_status_changes = true notify_nova_on_port_data_changes = true [keystone_authtoken] auth_uri = http://ctrl.test.com:5000 auth_url = http://ctrl.test.com:35357 memcached_servers = base.test.com:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = neutron password = NEUTRON_PASS [nova] auth_url = http://ctrl.test.com:35357 auth_type = password project_domain_name = default user_domain_name = default region_name = RegionOne project_name = service username = nova password = NOVA_PASS [oslo_concurrency] lock_path = /var/lib/neutron/tmp

 

#编辑ml2配置文件

vim /etc/neutron/plugins/ml2/ml2_conf.ini

[ml2] type_drivers = flat,vlan,gre,vxlan,geneve #type_drivers = flat,vlan,vxlan tenant_network_types = flat,vlan,gre,vxlan,geneve #tenant_network_types = vxlan mechanism_drivers = linuxbridge #mechanism_drivers = linuxbridge,l2population extension_drivers = port_security [ml2_type_flat] flat_networks = provider [securitygroup] enable_ipset = true #[ml2_type_vxlan] #vni_ranges = 1:1000

 

#编辑linuxbridge_agent配置文件

vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini

[linux_bridge] physical_interface_mappings = provider:eth1 [vxlan] enable_vxlan = false #enable_vxlan = true #local_ip = 172.16.2.52 #l2_population = true [securitygroup] enable_security_group = true firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

 

#编辑l3配置文件

#vim /etc/neutron/l3_agent.ini

[DEFAULT] #interface_driver = linuxbridge

 

#编辑dhcp配置文件

vim /etc/neutron/dhcp_agent.ini

[DEFAULT] interface_driver = linuxbridge dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq enable_isolated_metadata = true

 

#编辑metadata配置文件

vim /etc/neutron/metadata_agent.ini

[DEFAULT] nova_metadata_host =ctrl.test.com metadata_proxy_shared_secret = METADATA_SECRET

 

#编辑Nova配置文件

vim /etc/nova/nova.conf

[neutron] url = http://ctrl.test.com:9696 auth_url = http://ctrl.test.com:35357 auth_type = password project_domain_name = default user_domain_name = default region_name = RegionOne project_name = service username = neutron password = NEUTRON_PASS service_metadata_proxy = true metadata_proxy_shared_secret = METADATA_SECRET

 

#创建软连接

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

#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

 

#启动服务

systemctl restart openstack-nova-api.service

 

systemctl restart neutron-server.service \

neutron-linuxbridge-agent.service \

neutron-dhcp-agent.service \

neutron-metadata-agent.service

 

systemctl enable neutron-server.service \

neutron-linuxbridge-agent.service \

neutron-dhcp-agent.service \

neutron-metadata-agent.service

 

#systemctl restart neutron-l3-agent.service

#systemctl enable neutron-l3-agent.service

 

#验证（计算节点配置完成再验证）

. admin-openrc

openstack extension list --network

openstack network agent list

 

三、 com计算节点配置

#安装软件

yum install openstack-neutron-linuxbridge ebtables ipset -y

 

#编辑neutron配置文件

vim /etc/neutron/neutron.conf

[DEFAULT] transport_url = rabbit://openstack:RABBIT_PASS@base.test.com auth_strategy = keystone [keystone_authtoken] auth_uri = http://ctrl.test.com:5000 auth_url = http://ctrl.test.com:35357 memcached_servers = base.test.com:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = neutron password = NEUTRON_PASS [oslo_concurrency] lock_path = /var/lib/neutron/tmp

 

#编辑桥接配置文件

vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini

[linux_bridge] physical_interface_mappings = provider:eth0 [vxlan] enable_vxlan = false #enable_vxlan = true #local_ip = 172.16.2.53 #l2_population = true [securitygroup] enable_security_group = true firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

 

#编辑Nova配置文件

vim /etc/nova/nova.conf

[neutron] url = http://ctrl.test.com:9696 auth_url = http://ctrl.test.com:35357 auth_type = password project_domain_name = default user_domain_name = default region_name = RegionOne project_name = service username = neutron password = NEUTRON_PASS

 

#开启服务

systemctl restart openstack-nova-compute.service

 

systemctl restart neutron-linuxbridge-agent.service

systemctl enable neutron-linuxbridge-agent.service

 

注：配置文件中注释部分配置文件为创建L3路由网络使用的配置信息。未注释的配置信息为交换机网络。后续创建网络根据需要进行开启。注意，相同项保留一项即可。
