1 | ## 介绍 | |
|
|
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` 和 `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 | ||
|
|
4 | ## 构建环境所依赖的包 | |
|
|
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 | ||
|
|
7 | ```debootstrap debian-archive-keyring qemu-user-static binfmt-support dosfstools rsync bmap-tools whois git bc psmisc dbus sudo``` | |
|
|
8 | ||
|
|
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 | ||
|
|
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 | ||
|
|
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 | ||
|
|
15 | ``` | |
|
|
16 | echo "deb http://emdebian.org/tools/debian/ jessie main" > /etc/apt/sources.list.d/crosstools.list | |
|
|
17 | sudo -u nobody wget -O - http://emdebian.org/tools/debian/emdebian-toolchain-archive.key | apt-key add - | |
|
|
18 | dpkg --add-architecture armhf | |
|
|
19 | apt-get update | |
|
|
20 | ``` | |
|
|
21 | ||
|
|
22 | ## 命令行参数 | |
|
|
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 | ||
|
|
25 | ##### 命令行示例: | |
|
|
26 | ```shell | |
|
|
27 | ENABLE_UBOOT=true ./rpi23-gen-image.sh | |
|
|
28 | ENABLE_CONSOLE=false ENABLE_IPV6=false ./rpi23-gen-image.sh | |
|
|
29 | ENABLE_WM=xfce4 ENABLE_FBTURBO=true ENABLE_MINBASE=true ./rpi23-gen-image.sh | |
|
|

|
|
31 | APT_SERVER=ftp.de.debian.org APT_PROXY="http://127.0.0.1:3142/" ./rpi23-gen-image.sh | |
|

|
|
39 | RELEASE=stretch RPI_MODEL=3 ENABLE_WIRELESS=true ENABLE_MINBASE=true BUILD_KERNEL=true ./rpi23-gen-image.sh | |
|
|
40 | ``` | |
|
|
41 | ||
|
|
42 | ## 参数模板文件 | |
|
|
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 | ||
|
|
45 | ##### 命令行示例: | |
|
|
46 | ```shell | |
|
|
47 | CONFIG_TEMPLATE=rpi3stretch ./rpi23-gen-image.sh | |
|
|
48 | CONFIG_TEMPLATE=rpi2stretch ./rpi23-gen-image.sh | |
|
|
49 | ``` | |

|
|
373 | ||
|
|
374 | ## 理解脚本 | |
|
|
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 | ||
|
|
377 | | 脚本 | 说明 | | |
|
|
378 | | --- | --- | | |
|
|
379 | | `10-bootstrap.sh` | 生成基本系统 | | |
|
|
380 | | `11-apt.sh` | 设置 APT 仓库源 | | |
|
|
381 | | `12-locale.sh` | 设置 Locales 和 keyboard | | |
|
|
382 | | `13-kernel.sh` | 编译安装树莓派 2/3 内核 | | |
|
|
383 | | `14-fstab.sh` | 设置 fstab 和 initramfs | | |
|
|
384 | | `15-rpi-config.sh` | 设置 RPi2/3 config and cmdline | | |
|
|
385 | | `20-networking.sh` | 设置网络 | | |
|
|
386 | | `21-firewall.sh` | 设置防火墙 | | |
|
|
387 | | `30-security.sh` | 设置用户以及安全相关 | | |
|
|
388 | | `31-logging.sh` | 设置日志 | | |
|
|
389 | | `32-sshd.sh` | 设置 SSH 和公钥 | | |
|
|
390 | | `41-uboot.sh` | 编译设置 U-Boot | | |
|
|
391 | | `42-fbturbo.sh` | 编译设置 fbturbo Xorg 驱动 | | |
|
|
392 | | `50-firstboot.sh` | 首次启动执行的任务 | | |
|
|
393 | | `99-reduce.sh` | 缩小体积 | | |
|
|
394 | ||
|
|
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 | ||
|
|
397 | | 目录 | 说明 | | |
|
|
398 | | --- | --- | | |
|
|
399 | | `apt` | APT 管理配置文件 | | |
|
|
400 | | `boot` | 引导文件 树莓派2/3配置文件 | | |
|
|
401 | | `dpkg` | 包管理配置文件 | | |
|
|
402 | | `etc` | 配置文件以及 rc 启动脚本 | | |
|
|
403 | | `firstboot` | 首次引导执行的脚本 | | |
|
|
404 | | `initramfs` | Initramfs 脚本 | | |
|
|
405 | | `iptables` | 防火墙配置文件 | | |
|
|
406 | | `locales` | Locales 配置 | | |
|
|
407 | | `modules` | 内核模块配置 | | |
|
|
408 | | `mount` | Fstab 配置 | | |
|
|
409 | | `network` | 网络配置文件 | | |
|
|
410 | | `sysctl.d` | 交换文件以及IP协议加固配置文件 | | |
|
|
411 | | `xorg` | fbturbo Xorg 驱动配置 | | |
|
|
412 | ||
|
|
413 | ## 自定义包和脚本 | |
|
|
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 | `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 | ||
|
|
417 | ## 记录镜像产生过程的信息 | |
|
|
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 | ||
|
|
420 | ```shell | |
|
|
421 | script -c 'APT_SERVER=ftp.de.debian.org ./rpi23-gen-image.sh' ./build.log | |
|
|
422 | ``` | |
|
|
423 | ||
|
|
424 | ## 烧录镜像文件 | |
|
|
425 | `rpi23-gen-image.sh` 所生成的镜像文件需要使用 `bmaptool` 或 `dd` 烧录到 microSD 卡. `bmaptool` 速度快比 `dd` 聪明. | |
|
|
426 | ||
|
|
427 | ##### 烧录示例: | |
|
|
428 | ```shell | |
|
|
429 | bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie.img /dev/mmcblk0 | |
|
|
430 | dd bs=4M if=./images/jessie/2017-01-23-rpi3-jessie.img of=/dev/mmcblk0 | |
|
|
431 | ``` | |
|
|
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 | ```shell | |
|
|
434 | bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-frmw.img /dev/mmcblk0 | |
|
|
435 | bmaptool copy ./images/jessie/2017-01-23-rpi3-jessie-root.img /dev/sdc | |
|
|
436 | ``` | |
|
|
437 | ## 每周镜像 | |
|
|
438 | 这些镜像由JRWR'S I/O PORT提供, 每周日午夜UTC 0点编译! | |
