1. Controller 노드

1-1. DB 구축

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

1-2. 서비스 자격 증명 생성

엔드포인트의 주소에 노드의 IP 주소를 넣어준다.

# . admin-openrc
# openstack user create --domain default --password-prompt neutron

1-3. 네트워크 설정 - Self-service networks

네트워크 옵션에는 Provider networks와 Self-service networks가 있다. 이번 프로젝트에서는 단일 노드로 하기 때문에 Self-service networks으로 네트워크 설정을 한다.

1-3-1. 컴포넌트 설치

# # apt install neutron-server neutron-plugin-ml2 \
  neutron-linuxbridge-agent neutron-l3-agent neutron-dhcp-agent \
  neutron-metadata-agent

1-3-2. 서버 컴포넌트 구성

# vim /etc/neutron/neutron.conf
[database]
# ...
connection = mysql+pymysql://neutron:NEUTRON_DB_비밀번호PASS@localhost/neutron

[DEFAULT]
# ...
core_plugin = ml2
service_plugins = router
allow_overlapping_ips = true

transport_url = rabbit://openstack:RabbitMQ_비밀번호@localhost

auth_strategy = keystone

notify_nova_on_port_status_changes = true
notify_nova_on_port_data_changes = true


[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

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

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

1-3-3. ML2(Modular Layer 2) 플러그인 구성

# vim /etc/neutron/plugins/ml2/ml2_conf.ini
[ml2]
# ...
type_drivers = flat,vlan,vxlan
tenant_network_types = vxlan
mechanism_drivers = linuxbridge,l2population
extension_drivers = port_security

[ml2_type_flat]
# ...
flat_networks = provider
vni_ranges = 1:1000

[securitygroup]
# ...
enable_ipset = true

1-3-4.Linux bridge agent 구성

# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME

[vxlan]
enable_vxlan = true
local_ip = OVERLAY_INTERFACE_IP_ADDRESS
l2_population = true

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

1-3-5. 커널 파라미터 값 변경

# vim /etc/sysctl.conf 
# ...
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1

# sysctl -p

1-3-6. layer-3, DHCP agent 구성

# vim /etc/neutron/l3_agent.ini
[DEFAULT]
interface_driver = linuxbridge

# vim /etc/neutron/dhcp_agent.ini
[DEFAULT]
interface_driver = linuxbridge
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = true

1-4. Metadata agent 구성

# vim /etc/neutron/metadata_agent.ini

[DEFAULT]
nova_metadata_host = localhost
metadata_proxy_shared_secret = METADATA_SECRET

METADATA_SECRET은 적절한 secret으로 변경한다.

Nova를 설치한 후 

# vim /etc/nova/nova.conf

[neutron]
# ...
auth_url = http://localhost:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = NEUTRON_비밀번호
service_metadata_proxy = true
metadata_proxy_shared_secret = METADATA_SECRET

metadata_proxy_shared_secret은 위에서 설정한 secret을 입력한다.

1-5. 설치 완료

# 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
# service nova-api restart
# service neutron-server restart
# service neutron-linuxbridge-agent restart
# service neutron-dhcp-agent restart
# service neutron-metadata-agent restart
# service neutron-l3-agent restart

2. Compute 노드

원래는 두 노드를 사용해서 따로 설정을 해줘야 하지만 단일 노드를 사용하기 때문에 같은 노드에 설정을 해주면 된다. 이미 설정이 되어있다면 확인하고 넘어가면 된다.

2-1. components 설치

# apt install neutron-linuxbridge-agent

2-2. common component 구성

# vim /etc/neutron/neutron.conf
[DEFAULT]
# ...
transport_url = rabbit://openstack:RabbitMQ_비밀번호@localhost

auth_strategy = keystone

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

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

2-3. 네트워크 설정 - Self-service networks

2-3-1. Linux bridge agent 구성

# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME

[vxlan]
enable_vxlan = true
local_ip = OVERLAY_INTERFACE_IP_ADDRESS
l2_population = true

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

2-4. 컴퓨팅 서비스 구성

# vim /etc/nova/nova.conf
[neutron]
# ...
auth_url = http://localhost:5000
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = NEUTRON_비밀번호

2-5. 설치 완료

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