Instalando Neutron no Compute Node

Instalando Neutron no Compute Node

# yum install openstack-neutron-linuxbridge ebtables ipset -y

Configurando Neutron no Compute Node

/etc/neutron/neutron.conf:

[DEFAULT]
transport_url = rabbit://openstack:qwe123qwe@controller
auth_strategy = keystone

[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 = qwe123qwe

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

Configurando Linux Bridge no Compute Node

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

[linux_bridge]
physical_interface_mappings = provider:enp0s8
bridge_mappings = provider:enp0s8

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

[vxlan]
enable_vxlan = true
local_ip = 10.0.10.21
l2_population = true

Garantindo modulos de bridge carregados no Kernel Linux da Compute Node

modprobe br_netfilter
sysctl -w net.bridge.bridge-nf-call-iptables=1
sysctl -w net.bridge.bridge-nf-call-ip6tables=1

Garantindo serviços ativos do Neutron no Compute Node

# systemctl enable neutron-linuxbridge-agent.service
# systemctl start neutron-linuxbridge-agent.service

Reiniciar o serviço do Nova para que ele se comunique com Neutron

# systemctl restart openstack-nova-compute.service

======= REALIZAR OS COMANDOS QUE SEGUEM NA CONTROLLER =======

Confirmando Compute Node no database da Controller:

# openstack compute service list --service nova-compute

Realizando discover na Controller:

# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
