• 一：　在計算節點安裝neutron

# Install and configure compute node
https://docs.openstack.org/neutron/rocky/install/compute-install-rdo.html

安裝neutron組件

yum install openstack-neutron-linuxbridge ebtables ipset -y

快速配置/etc/neutron/neutron.conf

openstack-config --set /etc/neutron/neutron.conf DEFAULT transport_url  rabbit://openstack:openstack@controller
openstack-config --set /etc/neutron/neutron.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken www_authenticate_uri  http://controller:5000
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_url http://controller:5000
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken memcached_servers controller:11211
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken auth_type password
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken project_domain_name default
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken user_domain_name default
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken project_name service
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken username neutron
openstack-config --set /etc/neutron/neutron.conf keystone_authtoken password neutron
openstack-config --set /etc/neutron/neutron.conf oslo_concurrency lock_path /var/lib/neutron/tmp

---

egrep -v '(^$|^#)' /etc/neutron/neutron.conf

快速配置/etc/neutron/plugins/ml2/linuxbridge_agent.ini

openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini linux_bridge physical_interface_mappings  provider:ens33
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini vxlan enable_vxlan false
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup enable_security_group true
openstack-config --set /etc/neutron/plugins/ml2/linuxbridge_agent.ini securitygroup firewall_driver neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

配置nova計算服務與neutron網絡服務協同工做

openstack-config --set /etc/nova/nova.conf neutron url http://controller:9696
openstack-config --set /etc/nova/nova.conf neutron auth_url http://controller:5000
openstack-config --set /etc/nova/nova.conf neutron auth_type password
openstack-config --set /etc/nova/nova.conf neutron project_domain_name default
openstack-config --set /etc/nova/nova.conf neutron user_domain_name default
openstack-config --set /etc/nova/nova.conf neutron region_name RegionOne
openstack-config --set /etc/nova/nova.conf neutron project_name service 
openstack-config --set /etc/nova/nova.conf neutron username neutron
openstack-config --set /etc/nova/nova.conf neutron password neutron

從新啓動計算節點

systemctl restart openstack-nova-compute.service
systemctl status openstack-nova-compute.service

啓動neutron網絡組件，並配置開機自啓動

# 須要啓動1個服務，網橋代理
systemctl restart neutron-linuxbridge-agent.service
systemctl status neutron-linuxbridge-agent.service

systemctl enable neutron-linuxbridge-agent.service
systemctl list-unit-files |grep neutron* |grep enabled

至此，計算節點的網絡配置完成，轉回到控制節點進行驗證操做

在控制節點檢查確認neutron服務安裝成功

# Verify operation
https://docs.openstack.org/neutron/rocky/install/verify.html

# 如下命令在控制節點執行
1）獲取管理權限
cd /openstack
source keystone-admin-pass.sh
2）列表查看加載的網絡插件
openstack extension list --network

neutron ext-list

查看網絡代理列表
openstack network agent list

正常狀況下：控制節點有3個服務，計算節點有1個服務，若是不是，須要檢查計算節點配置：網卡名稱，IP地址，端口，密碼等要素
