Ubuntu Server 20.04最小部署openstack Wallaby(五)——Neutron

Neutron是OpenStack管理網絡的服務，需要在Controller和Compute節點都做相應的配置。

1. Controller節點

建立資料庫(注意替換NEUTRON_DBPASS)

sudo mysql -u root -p
MariaDB [(none)] CREATE DATABASE neutron;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \
  IDENTIFIED BY 'NEUTRON_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \
  IDENTIFIED BY 'NEUTRON_DBPASS';

加載環境變量

. admin-openrc

建立使用者并加入角色

openstack user create --domain default --password-prompt neutron
openstack role add --project service --user neutron admin

建立服務

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

建立api端點

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

OpenStack有兩種網絡模式，這裡選用provider模式，安裝程式

sudo apt-get install neutron-server neutron-plugin-ml2 \
  neutron-linuxbridge-agent neutron-dhcp-agent \
  neutron-metadata-agent

修改配置檔案

sudo vim /etc/neutron/neutron.conf

修改database(注意替換NEUTRON_DBPASS)

[database]
# ...
connection = mysql+pymysql://neutron:[email protected]/neutron

修改Default(注意替換RABBIT_PASS)

[DEFAULT]
# ...
core_plugin = ml2
service_plugins =
transport_url = rabbit://openstack:[email protected]
auth_strategy = keystone
notify_nova_on_port_status_changes = true
notify_nova_on_port_data_changes = true

修改keystone_authtoken(注意替換NEUTRON_PASS)

[keystone_authtoken]
# ...
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = NEUTRON_PASS

修改nova(注意替換NOVA_PASS)

[nova]
# ...
auth_url = http://controller:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = nova
password = NOVA_PASS

修改oslo_concurrency

[oslo_concurrency]
# ...
lock_path = /var/lib/neutron/tmp

修改配置檔案

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

修改ml2

[ml2]
# ...
type_drivers = flat,vlan
tenant_network_types =
mechanism_drivers = linuxbridge
extension_drivers = port_security

修改ml2_type_flat

[ml2_type_flat]
# ...
flat_networks = provider

修改securitygroup

[securitygroup]
# ...
enable_ipset = true

修改配置檔案

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

修改linux_bridge，這裡PROVIDER_INTERFACE_NAME是實際的實體網卡接口名稱eno1，不是我們建立的虛拟網卡

[linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME

修改vxlan

[vxlan]
enable_vxlan = false

修改securitygroup

[securitygroup]
# ...
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

修改系統配置

sudo vim /etc/sysctl.conf

加入兩行

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

使之生效

sudo sysctl -p

修改配置檔案

sudo vim /etc/neutron/dhcp_agent.ini

修改Default

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

下面開始建立Provider網絡，首先加載環境變量

. admin-openrc

建立網絡

openstack network create  --share --external \
  --provider-physical-network provider \
  --provider-network-type flat provider

建立子網

openstack subnet create --network provider \
  --allocation-pool start=START_IP_ADDRESS,end=END_IP_ADDRESS \
  --dns-nameserver DNS_RESOLVER --gateway PROVIDER_NETWORK_GATEWAY \
  --subnet-range PROVIDER_NETWORK_CIDR provider

需要替換的變量

START_IP_ADDRESS：子網起始IP，如192.168.100.100

END_IP_ADDRESS：子網的結束IP，如192.168.100.250

DNS_RESOLVER：域名伺服器位址，如8.8.4.4

PROVIDER_NETWORK_GATEWAY：子網網關，如192.168.100.1

PROVIDER_NETWORK_CIDR：子網CIDR标記，如192.168.100.0/24

openstack subnet create --network provider \
  --allocation-pool start=192.168.0.200,end=192.168.0.250 \
  --dns-nameserver 114.114.114.114 --gateway 192.168.0.1 \
  --subnet-range 192.168.0.0/24 provider

修改配置檔案

sudo vim /etc/neutron/metadata_agent.ini

修改Default，注意METADATA_SECRET應該是和之前Compute節點配置的一樣

[DEFAULT]
# ...
nova_metadata_host = controller
metadata_proxy_shared_secret = METADATA_SECRET

建立資料庫

sudo 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

重新開機nova-api服務

sudo service nova-api restart

啟動網絡服務

sudo service neutron-server restart
sudo service neutron-linuxbridge-agent restart
sudo service neutron-dhcp-agent restart
sudo service neutron-metadata-agent restart

2. Compute節點

安裝程式

sudo apt-get install neutron-linuxbridge-agent

修改配置檔案

sudo vim /etc/neutron/neutron.conf

修改Default(注意替換RABBIT_PASS)

[DEFAULT]
# ...
transport_url = rabbit://openstack:[email protected]
auth_strategy = keystone

修改keystone_authtoken(注意替換NEUTRON_PASS)

[keystone_authtoken]
# ...
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = NEUTRON_PASS

修改oslo_concurrency

[oslo_concurrency]
# ...
lock_path = /var/lib/neutron/tmp

修改配置檔案

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

修改linux_bridge，這裡PROVIDER_INTERFACE_NAME是對外的實體網卡名稱，如eno1

[linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME

修改vxlan

[vxlan]
enable_vxlan = false

修改securitygroup

[securitygroup]
# ...
enable_security_group = true
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

 修改系統配置

sudo vim /etc/sysctl.conf

加入兩行

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

使之生效

sudo sysctl -p

重新開機服務

sudo service nova-compute restart
sudo service neutron-linuxbridge-agent restart

3. 驗證服務

. admin-openrc
openstack network agent list

應該看到四個active的服務
