• 因为是裸机环境，所以关闭 Nova Scheduler 跟踪虚拟机信息

[filter_scheduler]
track_instance_changes=False

• 重启 Nova Scheduler

systemctl restart openstack-nova-scheduler

配置 Neutron 提供 Provisioning Network

抽象网络模型

• Provisioning Network 是注册并部署裸金属实例的网络，所以要求连通 IPMI、DHCP、PXE 以及裸金属服务器。其中 DHCP 由 Neutron DHCP Agent 提供，PXE 由 Ironic Conductor 提供。有 Flat、VLAN、SDN 等多种方案，本文选择使用 Flat 类型。
• Cleaning Network 是初始化裸金属节点的网络，主要完成抹盘、初始化硬件配置信息等工作，所以要求连通 IPMI 以及裸金属服务器。
• Tenant Network 是常规的 Neutron 租户网络，在裸金属服务器部署完成之后会将裸金属节点的部署端口（PXE 网卡）从 Provisioning Network 切换到 Tenant Network。在此之上可以通过 L3 Router 完成裸机与虚拟机的跨网络通信。

Flat 网络模型

Flat 网络模型下，所有的物理服务器（裸金属节点、OpenSack 节点）都处于同一个 Flat（扁平）网络中，无需交换机或者为透明交换机。物理机网络由运维人员完成预配置，Neutron 在 Flat 网络模型中只负责提供 DHCP 服务。

• IPMI OOB Network、OpenStack MGMT Network 二层互通：Ironic Conductor 节点可以通过 ipmitool 管理 BM Node。
• Provisioning Network 复用 External Network 与 BM Nodes 二层互通：BM Node 可以从 Provisioning Network DHCP 获取到 IP 地址和 TFTP 服务器的访问接口。
• OpenStack MGMT Network 与 External Network 二层互通：BM Node 可以经 OpenStack MGMT Network 访问到 TFTP 服务器；运行在 BM Node 上的 IPA 与 Ironic Conductor 通信。

VLAN 网络模型

VLAN 网络模型下，Neutron 可以通过 Networking Generic Switch 来实现对物理交换机的接管。 在此基础上无论是 Provisioning Network 还是 Tenant Network 都通过 VLAN 网络类型（Physical Network）接入到物理交换机，由 Neutron 完成对物理交换机端口配置的切换控制。比如：部署时，BM Node 接入端口为 Provisioning Network VLAN；部署完成后，BM Node 接入端口为 Tenant Network VLAN。

• Provisioning Network 与 Tenant Network 复用一个 VLAN Physical Network，并具有不同的 VLAN ID。
• Provisioning Network、Tenant Network、BM Nodes 全部接入一个二层交换网络，通过对 BM Node 上联端口 VLAN ID 的动态配置实现 BM Node 接入网络的切换。
  • 部署时，BM Node VLAN 接入 Provisioning Network：BM Node 从 DHCP 获取 IP 地址。
  • 部署完成后，BM Node VLAN 接入 Tenant Network：BM Node 与同租户网络中的其他节点互通。
• OpenStack MGMT Network 要求与 IPMI OOB Network、Provisioning Network、物理交换机管理 IP 打通，可以部署为同一个网络。
  • 与 IPMI OOB Network 打通：Ironic Conductor 通过 ipmitool 接管 IPMI。
  • 与 Provisioning Network 打通：BM Node 访问 TFTP 服务器；运行在 BM Node 上的 IPA 与 Ironic Conductor 通信。
  • 与物理交换机管理 IP 打通：Neutron 接管交换机。

配置 Open vSwitch Agent（Controller）

NOTE：因为在本文环境中已经存在一个基础的 OpenStack 环境，包括已经配置好了的 Flat Physical Network。这里本质的需求是打造一个可以提供 Provisioning Network 的基础网络配置，所以根据个人的实际情况来选择是否执行下列配置。

• 安装 OvS Agent

yum install openstack-neutron-openvswitch ipset -y

• 配置 OvS Agent

# /etc/neutron/plugins/ml2/openvswitch_agent.ini

[ovs]
datapath_type = system
bridge_mappings = provider:br-provider

[agent]
l2_population = True

[securitygroup]
firewall_driver = openvswitch

• 启动 vswitchd 守护进程

systemctl enable openvswitch
systemctl start openvswitch
systemctl status openvswitch

• 手动创建 OvS Provider Bridge

ovs-vsctl add-br br-provider
ovs-vsctl add-port br-provider ens192

• 启动 OvS Agent

systemctl enable neutron-openvswitch-agent.service
systemctl start neutron-openvswitch-agent.service
systemctl status neutron-openvswitch-agent.service

• 验证

[root@baremetal ~]# ovs-vsctl show

• 在 Neutron ML2 配置 Flat Physical Network，用于创建 Provisioning Network

# /etc/neutron/plugins/ml2/ml2_conf.ini

[ml2_type_flat]
flat_networks = provider,external

[ml2_type_vlan]
network_vlan_ranges = provider1:1:1000

[ml2_type_vxlan]
vni_ranges = 1:1000

• 重启 Neutron Server

systemctl restart neutron-server

配置 Networking-baremetal ML2 mechanism driver（Controller）[可选]

以往使用 Flat 网络接口时创建的裸机 Port 状态会一直处于 DOWN，但裸机操作系统的部署依然能够成功且正常工作。而 Networking-baremetal 项目正是希望解决裸机 Port 状态不正常的问题，该项目提供了网络服务和裸机服务深度集成的功能，不仅能完成裸机 Port 状态变更，还能提供 Routed Networks 功能。

PS：Routed Networks & Multi-Segments

Networking-baremetal ML2 mechanism driver 是一个 Neutron ML2 Mechanism Driver，主要用于 Fake Neutron Port Attach 动作，使其状态保存健康。但实际上 Networking-baremetal ML2 mechanism driver 是可选的。因为 Ironic Driver in Nova 的 Port Binding 允许失败。类比：

VM：将 Neutron Port 绑定到计算节点的 Tap
BM：将 Neutron Port Fake Attach

• 安装 Networking-baremetal ML2 mechanism driver

yum install python2-networking-baremetal -y

• 配置使用 Networking-baremetal ML2 mechanism driver

# /etc/neutron/plugins/ml2/ml2_conf.ini

[ml2]
type_drivers = local,flat,vlan,vxlan
tenant_network_types = vxlan
extension_drivers = port_security
mechanism_drivers = openvswitch,l2population,baremetal

• 重启服务

systemctl restart neutron-server

配置 Ironic Neutron Agent（Controller）[可选]

Ironic Neutron Agent 和 Networking-baremetal ML2 mechanism driver 配合使用。

• 安装 Ironic Neutron Agent

yum install -y python2-ironic-neutron-agent

• 配置 Ironic Neutron Agent

# /etc/neutron/plugins/ml2/ironic_neutron_agent.ini

[DEFAULT]
debug = true

[agent]
log_agent_heartbeats = true

[ironic]
project_domain_name = default
project_name = service
user_domain_name = default
password = fanguiju
username = ironic
auth_url = http://controller:5000/v3
auth_type = password
region_name = RegionOne

• 启动 Ironic Neutron Agent

systemctl enable ironic-neutron-agent
systemctl start ironic-neutron-agent
systemctl status ironic-neutron-agent

创建 Provisioning Network

如前文所述，我们创建一个 Flat 类型的 Provisioning Network，该网络的本质是一个运营商网络，通过运营商的物理交换机连通到裸金属服务器，使得裸金属服务器可以借助该网络的 DHCP 服务获取到 IP 地址和 PXE 服务器的信息。所以 Subnet 一定要 Enable DHCP。

openstack network create --project admin provisioning-net-1 --share --provider-network-type flat --provider-physical-network provider

openstack subnet create provisioning-subnet-1 --network provisioning-net-1 
  --subnet-range 172.18.22.0/24 --ip-version 4 --gateway 172.18.22.1 
  --allocation-pool start=172.18.22.237,end=172.18.22.240 --dhcp

配置 Neutron 提供 Cleaning Network（BareMetal）

本文环境将 Provisioning Network 和 Cleaning Network 合并。

• 获取 Provisioning Network UUID

• 配置 ironic-conductor

# /etc/ironic/ironic.conf

[neutron]
cleaning_network = b90fce07-0f32-4ba5-a1fd-a8e5e00f9c65

• 重启服务

systemctl restart openstack-ironic-conductor

配置 Ironic 使用 Neutron Networking（BareMetal）

• 修改配置让 Ironic 默认使用 Flat Network Interface 以及填入 Provisioning/Cleaning Network

# /etc/ironic/ironic.conf

[DEFAULT]
...
enabled_network_interfaces=noop,flat,neutron
default_network_interface=flat

[neutron]
...
cleaning_network = b90fce07-0f32-4ba5-a1fd-a8e5e00f9c65
cleaning_network_security_groups = b9ce73bb-58c1-44f6-91cf-f66d5f55f57f
provisioning_network = b90fce07-0f32-4ba5-a1fd-a8e5e00f9c65
provisioning_network_security_groups = b9ce73bb-58c1-44f6-91cf-f66d5f55f57f

NOTE: The “provisioning” and “cleaning” networks may be the same network or distinct networks. To ensure that communication between the Bare Metal service and the deploy ramdisk works, it is important to ensure that security groups are disabled for these networks, or that the default security groups allow:

• DHCP

• TFTP

• egress port used for the Bare Metal service (6385 by default)

• ingress port used for ironic-python-agent (9999 by default)

• if using iSCSI deploy, the ingress port used for iSCSI (3260 by default)

• if using Direct deploy, the egress port used for the Object Storage service (typically 80 or 443)

• if using iPXE, the egress port used for the HTTP server running on the ironic-conductor nodes (typically 80).

• 重启服务

systemctl restart openstack-ironic-api
systemctl restart openstack-ironic-conductor

         grub2 
         -o my-image

$ ls
my-image.d  my-image.initrd  my-image.qcow2  my-image.vmlinuz

The partition image command creates my-image.qcow2, my-image.vmlinuz and my-image.initrd files. The grub2 element in the partition image creation command is only needed if local boot will be used to deploy my-image.qcow2, otherwise the images my-image.vmlinuz and my-image.initrd will be used for PXE booting after deploying the bare metal with my-image.qcow2.

配置 Bare Metal Provisioning 驱动

根据裸机集群的具体厂商和硬件设备来配置 Bare Metal Provisioning Drivers。Ironic 支持的驱动类型非常之多，具体可浏览官方文档。

官方文档：Set up the drivers for the Bare Metal service

常见组合：

• pxe + ipmi：IPMI 控制硬件设备、使用 PXE 实施部署

• pxe + drac：DRAC 控制硬件设备、使用 PXE 实施部署

• pxe + ilo：iLO 控制硬件设备、使用 PXE 实施部署

• pxe + iboot：iBoot 控制硬件设备、使用 PXE 实施部署

• pxe + ssh：SSH 控制硬件设备、使用 PXE 实施部署

• 配置

# /etc/ironic/ironic.conf

[DEFAULT]
...
enabled_hardware_types = ipmi,redfish
# boot
enabled_boot_interfaces = pxe
# console
enabled_console_interfaces = ipmitool-socat,no-console
# deploy
enabled_deploy_interfaces = direct,iscsi
# inspect
enabled_inspect_interfaces = inspector
# management
enabled_management_interfaces = ipmitool,redfish
# power
enabled_power_interfaces = ipmitool,redfish
# raid
enabled_raid_interfaces = agent
# vendor
enabled_vendor_interfaces = ipmitool, no-vendor
# storage
enabled_storage_interfaces = cinder, noop
# network
enabled_network_interfaces = flat,neutron

• 重启

systemctl restart openstack-ironic-conductor

• 验证

[root@controller ~]# openstack baremetal driver list
+---------------------+----------------+
| Supported driver(s) | Active host(s) |
+---------------------+----------------+
| ipmi                | baremetal      |
| redfish             | baremetal      |
+---------------------+----------------+

配置 PXE 服务器

• 编辑

# /etc/ironic/ironic.conf

[ipmi]
retry_timeout=60

[pxe]
ipxe_enabled = False
pxe_append_params = nofb nomodeset vga=normal console=ttyS0 systemd.journald.forward_to_console=yes
tftp_root=/tftpboot
tftp_server=172.18.22.233

• 重启服务

systemctl restart openstack-ironic-conductor

配置 IPMI Tool

在 Ironic Conductor 节点安装 IPMI Tool。

• 安装

yum install ipmitool -y

• 验证

# ipmitool -I lanplus -H <ip-address> -U <username> -P <password> chassis power status

[root@baremetal ~]# ipmitool -I lanplus -H 172.18.22.106 -U admin -P admin chassis power status
Chassis Power is on

配置 TFTP 服务器

在 Ironic Conductor 节点配置 TFTP。

• 安装

sudo mkdir -p /tftpboot
sudo chown -R ironic /tftpboot
sudo yum install tftp-server syslinux-tftpboot xinetd -y

• 配置

# /etc/xinetd.d/tftp

service tftp
{
  protocol        = udp
  port            = 69
  socket_type     = dgram
  wait            = yes
  user            = root
  server          = /usr/sbin/in.tftpd
  server_args     = -v -v -v -v -v --map-file /tftpboot/map-file /tftpboot
  disable         = no
  flags           = IPv4
}

• 准备 pxelinux.0、chain.c32 文件

sudo cp /usr/share/syslinux/pxelinux.0 /tftpboot

# If whole disk images need to be deployed via PXE-netboot, copy the chain.c32 image to /tftpboot to support it
sudo cp /usr/share/syslinux/chain.c32 /tftpboot/

• If the version of syslinux is greater than 4 we also need to make sure that we copy the library modules into the /tftpboot directory. Create a map file in the tftp boot directory

echo 're ^(/tftpboot/) /tftpboot/2' > /tftpboot/map-file
echo 're ^/tftpboot/ /tftpboot/' >> /tftpboot/map-file
echo 're ^(^/) /tftpboot/1' >> /tftpboot/map-file
echo 're ^([^/]) /tftpboot/1' >> /tftpboot/map-file

• 启动

sudo systemctl enable xinetd
sudo systemctl restart xinetd
sudo systemctl status xinetd

• 验证

# 服务端
[root@baremetal ~]# echo 'test tftp' > /tftpboot/aaa

# 客户端
[root@controller ~]# tftp baremetal -c get aaa
[root@controller ~]# cat aaa
test tftp

配置支持 PXE UEFI

NOTE：Make sure that bare metal node is configured to boot in UEFI boot mode and boot device is set to network/pxe.

• Install Grub2 and shim packages

sudo yum install grub2-efi shim -y

• Copy grub and shim boot loader images to /tftpboot directory

sudo cp /boot/efi/EFI/centos/shim.efi /tftpboot/bootx64.efi
sudo cp /boot/efi/EFI/centos/grubx64.efi /tftpboot/grubx64.efi

• Create master grub.cfg

$ GRUB_DIR=/tftpboot/EFI/centos

$ sudo mkdir -p $GRUB_DIR

$ cat $GRUB_DIR/grub.cfg
set default=master
set timeout=5
set hidden_timeout_quiet=false

menuentry "master"  {
configfile /tftpboot/$net_default_mac.conf
}

$ sudo chmod 644 $GRUB_DIR/grub.cfg

• Update the bare metal node with boot_mode capability in node’s properties field

openstack baremetal node set <node-uuid> --property capabilities='boot_mode:uefi'

配置支持 iSCSI-base Driver

因为使用 iSCSI Deploy 方式的话，Ironic Conductor 节点会作为 iSCSI Client 并执行镜像的注入，所以需要安装 qemu-img 和 iscsiadm 指令行工具。

• 安装 QEMU 镜像操作工具

yum install qemu-img

• 安装 iSCSI 客户端

yum -y install iscsi-initiator-utils
