【Kickstart で CentOS7 自動インストール】
Kickstart 環境を構築し、CentOS7 を自動インストールする手順をまとめる
[Server: Kickstart 環境の構築]
1. TFTP server セットアップ
2. DHCP server セットアップ
3. FTP Server セットアップ (TFTP)
4. Kickstart 設定 (CentOS7インストール用)
[Client: Kickstart 環境の利用]
1. CentOS 自動インストール実行手順
4. Kickstart 設定 (CentOS7インストール用)
f. PXE ブート設定ファイル配置ディレクトリ作成
mkdir -p /var/lib/tftpboot/pxeboot/pxelinux.cfg/
g. PXE ブート設定ファイル作成
i. kickstart ファイル作成
オプションの詳細は RHEL7インストールマニュアル/23.3. キックスタート構文の参考資料 を参照

PXEにより、VirtualBoxでCentOS 7のインストーラーを起動した(図で解説あり)
5月 01, 2019
VirtualBox Version 5.2.20 r125813 (Qt5.6.3)、CentOS Linux release 7.6.1810 (Core)を用いて、PXEによるインストーラーの起動までを試した。
PXEサーバー、PXEクライアントともに、VirtualBoxの仮想マシン。
作業開始時点のPXEサーバーの状態は、Minimal ISOをインストールした直後とする。
SELinuxはEnforcing、firewalldはstopしないで必要なだけ開放した。
基本的に、Redhatの公式ドキュメントのやり方を踏襲した。
PXEについて
PXEは、ネットワークブートを実現する仕組み。
OSやインストーラーを、ネットワーク経由で起動できる。
Kickstartと組み合わせることで、Linux OSのインストールを自動化できる。
PXEに必要なサーバーは、下記の3つ。
DHCPサーバー - IPアドレス付与、TFTPサーバーとブートローダーの場所を教える
TFTPサーバー - ブートローダーを提供、インストールソースの場所を教える
ファイルサーバー(HTTP、FTP、NFSなど) - インストールソースを提供

Diskless Windows 10 PC Setup Procedure By scan80269,
Gigabit Ethernet NIC with PXE boot support
Gigabit Ethernet NIC, with driver for Windows Server
DHCP server static IPs
Contents of iscsi.ipxe (text) file: #!ipxe
sanboot iscsi:<server IP>::::iqn.1991-05.com.microsoft:<server name>-win10-target boot
Share iSCSIVirtualDisks folder with rear/write permission for client username
Create TFTProot folder
Put ipxe-undionly.kpxe and iscsi.ipxe files in C:\TFTProot
Download and set up Tiny PXE Server (Tiny PXE Server - reboot.pro)
Enable iSCSI Service
Client Connect network via gigabit Ethernet NIC and cable
Attach local storage (HDD/SSD)
Install Windows 10 OS into hard disk
- Copy OS install files into FAT32 formatted USB flash drive to use for OS installation
Install NIC driver and other device drivers (graphics, audio, etc.) as needed
Ensure client can properly browse on Internet
Launch iSCSI Initiator
- Type "iscsicpl" <Enter> at the Command Prompt window and answer Yes to the prompt
- This will configure Win10 to auto launch the iSCSI initiator service at OS startup
Launch Registry Editor (regedit.exe) to set boot flag for LAN driver
Locate the LAN driver service name under HKLM\SYSTEM\CurrentControlSet\Services
Example: for motherboards featuring Intel I217V/LM, I218V/LM, I219V/LM LAN the driver service name is: e1dexpress
Click on the driver service name, locate the Start key (REG_DWORD), double-click it and change its value to 0
- Repeat this Start key value change to 0 in HKLM\SYSTEM\ControlSet001\Services and HKLM\SYSTEM\ControlSet002\Services
Close Registry Editor
Download and run Disk2VHD.exe (from Microsoft Sysinternals: https://technet.microsoft.com/en-us/sysinternals/ee656415.aspx)
- Ensure "Use Vhdx" and "Use Volume Shadow Copy" checkboxes are checked
- In "VHD File Name" box, enter "\\<Server IP>\<share name>\Win10.VHDX (e.g. \\192.168.0.100\c\Win10.VHDX)
- Run Disk2VHD to create VHDX file on server
Server:
Set up iSCSI target LUN
Use "existing VHDX"
Add MAC address of client to iSCSI initiator list
Client:
Launch "iSCSI Initiator"
On "Discovery" tab, click "Discover Portal" and enter IP address or DNS name of server
on "Targets" tab, ensure a target appears on "Discovered targets" list
target name should look like: iqn.1991-05.com.microsoft:<server name>-Win10-target
Shut down Windows and detach hard disk from client
Power up client and it should proceed to PXE boot
- PXE boots to iPXE from server, then chains to iSCSI target LUN to start Windows 10 boot
Notes:
A. This procedure sets up a fixed size VHDX on the server. An alternative is to create a new dynamic VHDX (of desired max size) on the server, mount it locally (using iSCSI Initiator running on the server), connect the client disk to the server via USB-to-SATA adapter, then partition copy the client disk to the mounted VHDX. This preserves the dynamic nature of the VHDX file and helps conserve disk space on the server.
