1 1 ## 介绍
2 2 `rpi23-gen-image.sh` 是一个自动生成树莓派2/3系统镜像的脚本工具, 当前支持自动生成32位 armhf 架构的Debian, 发行版本`jessie`, `stretch``buster`. 树莓派3 64位镜像需要使用特定的配置参数 (```templates/rpi3-stretch-arm64-4.11.y```).
3 3
4 4 ## 构建环境所依赖的包
5 5 一定要安装好下列deb包, 他们是构建过程需要的核心包. 脚本会自动检查, 如果缺少,经用户确认后会自动安装.
6 6
7 7 ```debootstrap debian-archive-keyring qemu-user-static binfmt-support dosfstools rsync bmap-tools whois git bc psmisc dbus sudo```
8 8
9 9 推荐通过配置 `rpi23-gen-image.sh` 脚本编译安装最新的树莓派 Linux 内核, 对于树莓派3, 只能如此. 在构建系统上使用 ARM (armhf) 交叉编译工具链编译内核.
10 10
11 11 脚本已经在Debian Liux `jessie` 和`stretch` 构建系统下使用默认的 `crossbuild-essential-armhf` 工具链进行过测试. 获取更多信息请查看 [Debian 交叉工具链 Wiki](https://wiki.debian.org/CrossToolchains) .
12 12
13 13 如果使用Debian Linux `jessie` 构建系统, 先要添加交叉编译工具链的源 [Debian 交叉工具链仓库](http://emdebian.org/tools/debian/):
14 14
15 15 ```
16 16 echo "deb http://emdebian.org/tools/debian/ jessie main" > /etc/apt/sources.list.d/crosstools.list
17 17 sudo -u nobody wget -O - http://emdebian.org/tools/debian/emdebian-toolchain-archive.key | apt-key add -
18 18 dpkg --add-architecture armhf
19 19 apt-get update
20 20 ```
21 21
22 22 ## 命令行参数
23 23 脚本可以使用特定的命令行参数来允许或禁止操作系统的某些特性、服务和配置信息. 这些参数通过(简单)脚本变量传递给 `rpi23-gen-image.sh`. 不同于环境变量, (简单)脚本变量在调用`rpi23-gen-image.sh`的命令行前面定义.
24 24
25 25 ##### 命令行示例:
26 26 ```shell
27 27 ENABLE_UBOOT=true ./rpi23-gen-image.sh
28 28 ENABLE_CONSOLE=false ENABLE_IPV6=false ./rpi23-gen-image.sh
29 29 ENABLE_WM=xfce4 ENABLE_FBTURBO=true ENABLE_MINBASE=true ./rpi23-gen-image.sh
30 30 ENABLE_HARDNET=true ENABLE_IPTABLES=true /rpi23-gen-image.sh
31 31 APT_SERVER=ftp.de.debian.org APT_PROXY="http://127.0.0.1:3142/" ./rpi23-gen-image.sh
32 32 ENABLE_MINBASE=true ./rpi23-gen-image.sh
33 33 BUILD_KERNEL=true ENABLE_MINBASE=true ENABLE_IPV6=false ./rpi23-gen-image.sh
34 34 BUILD_KERNEL=true KERNELSRC_DIR=/tmp/linux ./rpi23-gen-image.sh
35 35 ENABLE_MINBASE=true ENABLE_REDUCE=true ENABLE_MINGPU=true BUILD_KERNEL=true ./rpi23-gen-image.sh
36 36 ENABLE_CRYPTFS=true CRYPTFS_PASSWORD=changeme EXPANDROOT=false ENABLE_MINBASE=true ENABLE_REDUCE=true ENABLE_MINGPU=true BUILD_KERNEL=true ./rpi23-gen-image.sh
37 37 RELEASE=stretch BUILD_KERNEL=true ./rpi23-gen-image.sh
38 38 RPI_MODEL=3 ENABLE_WIRELESS=true ENABLE_MINBASE=true BUILD_KERNEL=true ./rpi23-gen-image.sh
39 39 RELEASE=stretch RPI_MODEL=3 ENABLE_WIRELESS=true ENABLE_MINBASE=true BUILD_KERNEL=true ./rpi23-gen-image.sh
40 40 ```
41 41
42 42 ## 参数模板文件
43 43 为了避免冗长的命令行参数以及存储感兴趣的参数配置, `rpi23-gen-image.sh` 支持所谓的参数模板文件 (`CONFIG_TEMPLATE`=template). 这些文本文件位于 `./templates` 目录, 文件中含有将会使用的配置参数. 新的配置模板文件会被添加到 `./templates` 目录.
44 44
45 45 ##### 命令行示例:
46 46 ```shell
47 47 CONFIG_TEMPLATE=rpi3stretch ./rpi23-gen-image.sh
48 48 CONFIG_TEMPLATE=rpi2stretch ./rpi23-gen-image.sh
49 49 ```

367 367 #### Build settings构建设置:
368 368 ##### `BASEDIR`=$(pwd)/images/${RELEASE}
369 369 设置产生镜像的目录.
370 370
371 371 ##### `IMAGE_NAME`=${BASEDIR}/${DATE}-${KERNEL_ARCH}-${KERNEL_BRANCH}-rpi${RPI_MODEL}-${RELEASE}-${RELEASE_ARCH}
372 372 设置镜像文件名. 如果`ENABLE_SPLITFS`=false则文件名$IMAGE_NAME.img 如果`ENABLE_SPLITFS`=true则文件名$IMAGE_NAME-frmw.img 和 $IMAGE_NAME-root.img. 如果没有设置 `KERNEL_BRANCH` 则使用 "CURRENT" .
373 373
374 374 ## 理解脚本
375 375 制作镜像的每个阶段所实现的功能都由各自的脚本完成, 位于 `bootstrap.d` 目录. 按着字典序执行:
376 376
377 377 | 脚本 | 说明 |
378 378 | --- | --- |
379 379 | `10-bootstrap.sh` | 生成基本系统 |
380 380 | `11-apt.sh` | 设置 APT 仓库源 |
381 381 | `12-locale.sh` | 设置 Locales 和 keyboard |
382 382 | `13-kernel.sh` | 编译安装树莓派 2/3 内核 |
383 383 | `14-fstab.sh` | 设置 fstab 和 initramfs |
384 384 | `15-rpi-config.sh` | 设置 RPi2/3 config and cmdline |
385 385 | `20-networking.sh` | 设置网络 |
386 386 | `21-firewall.sh` | 设置防火墙 |
387 387 | `30-security.sh` | 设置用户以及安全相关 |
388 388 | `31-logging.sh` | 设置日志 |
389 389 | `32-sshd.sh` | 设置 SSH 和公钥 |
390 390 | `41-uboot.sh` | 编译设置 U-Boot |
391 391 | `42-fbturbo.sh` | 编译设置 fbturbo Xorg 驱动 |
392 392 | `50-firstboot.sh` | 首次启动执行的任务 |
393 393 | `99-reduce.sh` | 缩小体积 |
394 394
395 395 所有需要拷贝到镜像文件的配置文件都位于 `files` 目录. 最好不要手动更改这些配置文件.
396 396
397 397 | 目录 | 说明 |
398 398 | --- | --- |
399 399 | `apt` | APT 管理配置文件 |
400 400 | `boot` | 引导文件 树莓派2/3配置文件 |
401 401 | `dpkg` | 包管理配置文件 |
402 402 | `etc` | 配置文件以及 rc 启动脚本 |
403 403 | `firstboot` | 首次引导执行的脚本 |
404 404 | `initramfs` | Initramfs 脚本 |
405 405 | `iptables` | 防火墙配置文件 |
406 406 | `locales` | Locales 配置 |
407 407 | `modules` | 内核模块配置 |

410 410 | `sysctl.d` | 交换文件以及IP协议加固配置文件 |
411 411 | `xorg` | fbturbo Xorg 驱动配置 |
412 412
413 413 ## 自定义包和脚本
414 414 `packages` 目录里放置自定义deb包, 比如系统仓库里没有的软件.在安装完系统仓库中的包之后安装. 自定义包所依赖的deb包会自动从系统仓库下载. 不要把自定义包添加到 `APT_INCLUDES` 参数中.
415 415 `custom.d` 目录中的脚本会在其它安装都完成后, 创建镜像文件之前执行.
416 416
417 417 ## 记录镜像产生过程的信息
418 418 所有镜像产生过程的信息、`rpi23-gen-image.sh` 脚本执行的命令都可以通过shell的 `script` 命令保存到日志文件中:
419 419
420 420 ```shell
421 421 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
422 422 ```
423 423
424 424 ## 烧录镜像文件
425 425 `rpi23-gen-image.sh` 所生成的镜像文件需要使用 `bmaptool``dd` 烧录到 microSD 卡. `bmaptool` 速度快比 `dd` 聪明.
426 426
427 427 ##### 烧录示例:
428 428 ```shell
429 429 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie.img /dev/mmcblk0
430 430 dd bs=4M if=./images/jessie/2017-01-23-rpi3-jessie.img of=/dev/mmcblk0
431 431 ```
432 432 如果设置过 `ENABLE_SPLITFS`, 烧录 `-frmw` 文件到 microSD 卡, 烧录 `-root` 文件到 USB 驱动器:
433 433 ```shell
434 434 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-frmw.img /dev/mmcblk0
435 435 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-root.img /dev/sdc
436 436 ```

1 1 # rpi23-gen-image
2 2 ## Introduction
3 3
4 4 `rpi23-gen-image.sh` is an advanced Debian Linux bootstrapping shell script for generating Debian OS images for Raspberry Pi 2 (RPi2) and Raspberry Pi 3 (RPi3) computers. The script at this time supports the bootstrapping of the Debian (armhf) releases `jessie`, `stretch` and `buster`. Raspberry Pi 3 images are generated for 32-bit mode only. Raspberry Pi 3 64-bit images can be generated using custom configuration parameters (```templates/rpi3-stretch-arm64-4.11.y```).
5 5
6 6 ## Build dependencies
7 7 The following list of Debian packages must be installed on the build system because they are essentially required for the bootstrapping process. The script will check if all required packages are installed and missing packages will be installed automatically if confirmed by the user.
8 8
9 9 ```debootstrap debian-archive-keyring qemu-user-static binfmt-support dosfstools rsync bmap-tools whois git bc psmisc dbus sudo```
10 10
11 11 It is recommended to configure the `rpi23-gen-image.sh` script to build and install the latest Raspberry Pi Linux kernel. For the RPi3 this is mandatory. Kernel compilation and linking will be performed on the build system using an ARM (armhf) cross-compiler toolchain.
12 12
13 13 The script has been tested using the default `crossbuild-essential-armhf` toolchain meta package on Debian Linux `jessie` and `stretch` build systems. Please check the [Debian CrossToolchains Wiki](https://wiki.debian.org/CrossToolchains) for further information.
14 14
15 15 If a Debian Linux `jessie` build system is used it will be required to add the [Debian Cross-toolchains repository](http://emdebian.org/tools/debian/) first:
16 16
17 17 ```
18 18 echo "deb http://emdebian.org/tools/debian/ jessie main" > /etc/apt/sources.list.d/crosstools.list
19 19 sudo -u nobody wget -O - http://emdebian.org/tools/debian/emdebian-toolchain-archive.key | apt-key add -
20 20 dpkg --add-architecture armhf
21 21 apt-get update
22 22 ```
23 23
24 24 ## Command-line parameters
25 25 The script accepts certain command-line parameters to enable or disable specific OS features, services and configuration settings. These parameters are passed to the `rpi23-gen-image.sh` script via (simple) shell-variables. Unlike environment shell-variables (simple) shell-variables are defined at the beginning of the command-line call of the `rpi23-gen-image.sh` script.
26 26
27 27 ##### Command-line examples:
28 28 ```shell
29 29 ENABLE_UBOOT=true ./rpi23-gen-image.sh
30 30 ENABLE_CONSOLE=false ENABLE_IPV6=false ./rpi23-gen-image.sh
31 31 ENABLE_WM=xfce4 ENABLE_FBTURBO=true ENABLE_MINBASE=true ./rpi23-gen-image.sh
32 32 ENABLE_HARDNET=true ENABLE_IPTABLES=true /rpi23-gen-image.sh
33 33 APT_SERVER=ftp.de.debian.org APT_PROXY="http://127.0.0.1:3142/" ./rpi23-gen-image.sh
34 34 ENABLE_MINBASE=true ./rpi23-gen-image.sh
35 35 BUILD_KERNEL=true ENABLE_MINBASE=true ENABLE_IPV6=false ./rpi23-gen-image.sh
36 36 BUILD_KERNEL=true KERNELSRC_DIR=/tmp/linux ./rpi23-gen-image.sh
37 37 ENABLE_MINBASE=true ENABLE_REDUCE=true ENABLE_MINGPU=true BUILD_KERNEL=true ./rpi23-gen-image.sh
38 38 ENABLE_CRYPTFS=true CRYPTFS_PASSWORD=changeme EXPANDROOT=false ENABLE_MINBASE=true ENABLE_REDUCE=true ENABLE_MINGPU=true BUILD_KERNEL=true ./rpi23-gen-image.sh
39 39 RELEASE=stretch BUILD_KERNEL=true ./rpi23-gen-image.sh
40 40 RPI_MODEL=3 ENABLE_WIRELESS=true ENABLE_MINBASE=true BUILD_KERNEL=true ./rpi23-gen-image.sh
41 41 RELEASE=stretch RPI_MODEL=3 ENABLE_WIRELESS=true ENABLE_MINBASE=true BUILD_KERNEL=true ./rpi23-gen-image.sh
42 42 ```
43 43
44 44 ## Configuration template files
45 45 To avoid long lists of command-line parameters and to help to store the favourite parameter configurations the `rpi23-gen-image.sh` script supports so called configuration template files (`CONFIG_TEMPLATE`=template). These are simple text files located in the `./templates` directory that contain the list of configuration parameters that will be used. New configuration template files can be added to the `./templates` directory.
46 46
47 47 ##### Command-line examples:
48 48 ```shell
49 49 CONFIG_TEMPLATE=rpi3stretch ./rpi23-gen-image.sh
50 50 CONFIG_TEMPLATE=rpi2stretch ./rpi23-gen-image.sh
51 51 ```
52 52
53 53 ## Supported parameters and settings
54 54 #### APT settings:
55 55 ##### `APT_SERVER`="ftp.debian.org"
56 56 Set Debian packages server address. Choose a server from the list of Debian worldwide [mirror sites](https://www.debian.org/mirror/list). Using a nearby server will probably speed-up all required downloads within the bootstrapping process.
57 57
58 58 ##### `APT_PROXY`=""
59 59 Set Proxy server address. Using a local Proxy-Cache like `apt-cacher-ng` will speed-up the bootstrapping process because all required Debian packages will only be downloaded from the Debian mirror site once.
60 60
61 61 ##### `APT_INCLUDES`=""
62 62 A comma separated list of additional packages to be installed by debootstrap during bootstrapping.
63 63
64 64 ##### `APT_INCLUDES_LATE`=""
65 65 A comma separated list of additional packages to be installed by apt after bootstrapping and after APT sources are set up. This is useful for packages with pre-depends, which debootstrap do not handle well.
66 66
67 67 ---
68 68
69 69 #### General system settings:
70 70 ##### `RPI_MODEL`=2

375 391
376 392 ## Understanding the script
377 393 The functions of this script that are required for the different stages of the bootstrapping are split up into single files located inside the `bootstrap.d` directory. During the bootstrapping every script in this directory gets executed in lexicographical order:
378 394
379 395 | Script | Description |
380 396 | --- | --- |
381 397 | `10-bootstrap.sh` | Debootstrap basic system |
382 398 | `11-apt.sh` | Setup APT repositories |
383 399 | `12-locale.sh` | Setup Locales and keyboard settings |
384 400 | `13-kernel.sh` | Build and install RPi2/3 Kernel |
385 401 | `14-fstab.sh` | Setup fstab and initramfs |
386 402 | `15-rpi-config.sh` | Setup RPi2/3 config and cmdline |
387 403 | `20-networking.sh` | Setup Networking |
388 404 | `21-firewall.sh` | Setup Firewall |
389 405 | `30-security.sh` | Setup Users and Security settings |
390 406 | `31-logging.sh` | Setup Logging |
391 407 | `32-sshd.sh` | Setup SSH and public keys |
392 408 | `41-uboot.sh` | Build and Setup U-Boot |
393 409 | `42-fbturbo.sh` | Build and Setup fbturbo Xorg driver |
394 410 | `50-firstboot.sh` | First boot actions |
395 411 | `99-reduce.sh` | Reduce the disk space usage |
396 412
397 413 All the required configuration files that will be copied to the generated OS image are located inside the `files` directory. It is not recommended to modify these configuration files manually.
398 414
399 415 | Directory | Description |
400 416 | --- | --- |
401 417 | `apt` | APT management configuration files |
402 418 | `boot` | Boot and RPi2/3 configuration files |
403 419 | `dpkg` | Package Manager configuration |
404 420 | `etc` | Configuration files and rc scripts |
405 421 | `firstboot` | Scripts that get executed on first boot |
406 422 | `initramfs` | Initramfs scripts |
407 423 | `iptables` | Firewall configuration files |
408 424 | `locales` | Locales configuration |
409 425 | `modules` | Kernel Modules configuration |
410 426 | `mount` | Fstab configuration |
411 427 | `network` | Networking configuration files |
412 428 | `sysctl.d` | Swapping and Network Hardening configuration |
413 429 | `xorg` | fbturbo Xorg driver configuration |
414 430
415 431 ## Custom packages and scripts
416 432 Debian custom packages, i.e. those not in the debian repositories, can be installed by placing them in the `packages` directory. They are installed immediately after packages from the repositories are installed. Any dependencies listed in the custom packages will be downloaded automatically from the repositories. Do not list these custom packages in `APT_INCLUDES`.
417 433
418 434 Scripts in the custom.d directory will be executed after all other installation is complete but before the image is created.
419 435
420 436 ## Logging of the bootstrapping process
421 437 All information related to the bootstrapping process and the commands executed by the `rpi23-gen-image.sh` script can easily be saved into a logfile. The common shell command `script` can be used for this purpose:
422 438
423 439 ```shell
424 440 script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log
425 441 ```
426 442
427 443 ## Flashing the image file
428 444 After the image file was successfully created by the `rpi23-gen-image.sh` script it can be copied to the microSD card that will be used by the RPi2/3 computer. This can be performed by using the tools `bmaptool` or `dd`. Using `bmaptool` will probably speed-up the copy process because `bmaptool` copies more wisely than `dd`.
429 445
430 446 ##### Flashing examples:
431 447 ```shell
432 448 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie.img /dev/mmcblk0
433 449 dd bs=4M if=./images/jessie/2017-01-23-rpi3-jessie.img of=/dev/mmcblk0
434 450 ```
435 451 If you have set `ENABLE_SPLITFS`, copy the `-frmw` image on the microSD card, then the `-root` one on the USB drive:
436 452 ```shell
437 453 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-frmw.img /dev/mmcblk0
438 454 bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-root.img /dev/sdc
439 455 ```
456
457 ## QEMU emulation
458 Start QEMU full system emulation:
459 ```shell
460 qemu-system-arm -m 2048M -M vexpress-a15 -cpu cortex-a15 -kernel kernel7.img -no-reboot -dtb vexpress-v2p-ca15_a7.dtb -sd ${IMAGE_NAME}.qcow2 -append "root=/dev/mmcblk0p2 rw rootfstype=ext4 console=tty1"
461 ```
462
463 Start QEMU full system emulation and output to console:
464 ```shell
465 qemu-system-arm -m 2048M -M vexpress-a15 -cpu cortex-a15 -kernel kernel7.img -no-reboot -dtb vexpress-v2p-ca15_a7.dtb -sd ${IMAGE_NAME}.qcow2 -append "root=/dev/mmcblk0p2 rw rootfstype=ext4 console=ttyAMA0,115200 init=/bin/systemd" -serial stdio
466 ```
467
468 Start QEMU full system emulation with SMP and output to console:
469 ```shell
470 qemu-system-arm -m 2048M -M vexpress-a15 -cpu cortex-a15 -smp cpus=2,maxcpus=2 -kernel kernel7.img -no-reboot -dtb vexpress-v2p-ca15_a7.dtb -sd ${IMAGE_NAME}.qcow2 -append "root=/dev/mmcblk0p2 rw rootfstype=ext4 console=ttyAMA0,115200 init=/bin/systemd" -serial stdio
471 ```
472
473 Start QEMU full system emulation with cryptfs, initramfs and output to console:
474 ```shell
475 qemu-system-arm -m 2048M -M vexpress-a15 -cpu cortex-a15 -kernel kernel7.img -no-reboot -dtb vexpress-v2p-ca15_a7.dtb -sd ${IMAGE_NAME}.qcow2 -initrd "initramfs-${KERNEL_VERSION}" -append "root=/dev/mapper/secure cryptdevice=/dev/mmcblk0p2:secure rw rootfstype=ext4 console=ttyAMA0,115200 init=/bin/systemd" -serial stdio
476 ```
