• 一：　在计算节点安装neutron

---

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

安装neutron组件

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计算服务与neutron网络服务协同工做

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

从新启动计算节点

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

启动neutron网络组件，并配置开机自启动

# 须要启动1个服务，网桥代理
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，计算节点的网络配置完成，转回到控制节点进行验证操做

在控制节点检查确认neutron服务安装成功

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

# 如下命令在控制节点执行
1）获取管理权限
cd /openstack
source keystone-admin-pass.sh
2）列表查看加载的网络插件
openstack extension list --network

neutron ext-list

查看网络代理列表
openstack network agent list

正常状况下：控制节点有3个服务，计算节点有1个服务，若是不是，须要检查计算节点配置：网卡名称，IP地址，端口，密码等要素
