平台: ubuntu-22.04-desktop-amd64.
对象: debian rootfs、qemu.
文件: linux-6.1.26.tar.xz
本例通过qemu运行debian rootfs for arm64。
1.安装依赖
$ sudo apt install binfmt-support qemu-user-static qemu-system-aarch64 gcc-aarch64-linux-gnu debootstrap
2.下载文件
linux-6.1.26.tar.xz
[https://mirrors.edge.kernel.org/pub/linux/kernel/v6.x/linux-6.1.26.tar.xz]
debian rootfs
$ mkdir rootfs $ sudo qemu-debootstrap --arch arm64 --variant=minbase --include=whiptail,ca-certificates,tzdata buster rootfs https://mirrors.ustc.edu.cn/debian/
参数说明:
minbase: 包含必要的包和apt包管理器;
buildd: 包含编译工具包;
fakechroot: 包含不用root权限的包;
scratchbox: 包含scratchbox(交叉编译工具链)相关包;
另外,制作ubuntu rootfs与制作debian rootfs类似,下载ubuntu rootfs如下(除此之外的以下其它步骤通用):
$ sudo qemu-debootstrap --arch arm64 --variant=minbase --include=whiptail,ca-certificates,tzdata jammy rootfs https://mirrors.ustc.edu.cn/ubuntu-ports/
3.编译内核
$ make defconfig ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- $ make -j8 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
4.创建文件系统
$ dd if=/dev/zero of=debian10-base.ext4 bs=1M count=1024 $ mkfs.ext4 debian10-base.ext4 $ sudo mount -t ext4 debian10-base.ext4 /mnt/ $ sudo cp -raf rootfs/* /mnt/ $ sudo cp /usr/bin/qemu-aarch64-static /mnt/usr/bin/ $ sudo cp /etc/resolv.conf /mnt/etc/ $ sudo mount -t proc /proc /mnt/proc $ sudo mount -t sysfs /sys /mnt/sys $ sudo mount -o bind /dev /mnt/dev $ sudo mount -o bind /dev/pts /mnt/dev/pts
安装内核模块:
cd linux-6.1.26/ sudo make modules_install ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- INSTALL_MOD_PATH=/mnt cd ..
5.chroot
$ sudo chroot /mnt
进入chroot环境:
$ apt update $ apt install systemd sudo rsyslog udev $ useradd -s '/bin/bash' -m -G adm,sudo hellouser $ passwd hellouser $ echo "debian10" > /etc/hostname $ cp /lib/systemd/system/serial-getty\@.service /lib/systemd/system/serial-getty\@ttyAMA0.service $ systemctl enable serial-getty\@ttyAMA0.service $ exit
然后执行:
$ sudo vim /mnt/lib/systemd/system/[email protected]
其中[serial-getty\@ttyAMA0.service]做如下修改:
--- lib/systemd/system/[email protected] +++ lib/systemd/system/[email protected] @@ -11,8 +11,8 @@ Description=Serial Getty on %I Documentation=man:agetty(8) man:systemd-getty-generator(8) Documentation=http://0pointer.de/blog/projects/serial-console.html -BindsTo=dev-%i.device -After=dev-%i.device systemd-user-sessions.service plymouth-quit-wait.service getty-pre.target +#BindsTo=dev-%i.device +#After=dev-%i.device systemd-user-sessions.service plymouth-quit-wait.service getty-pre.target After=rc-local.service # If additional gettys are spawned during boot then we should make
卸载:
$ sudo umount /mnt/proc $ sudo umount /mnt/sys $ sudo umount /mnt/dev/pts $ sudo umount /mnt/dev $ sudo umount /mnt
6.运行
$ touch start-qemu.sh $ chmod +x start-qemu.sh
start-qemu.sh添加如下内容:
#!/bin/sh qemu-system-aarch64 \ -M virt \ -cpu cortex-a53 \ -nographic \ -smp 1 \ -m 1024M \ -kernel linux-6.1.26/arch/arm64/boot/Image \ -append "rootwait root=/dev/vda rw console=ttyAMA0" \ -netdev user,id=eth0 \ -device virtio-net-device,netdev=eth0 \ -drive file=debian10-base.ext4,if=none,format=raw,id=hd0 \ -device virtio-blk-device,drive=hd0
执行start-qemu.sh,顺利的话,就可以进入ubuntu base了,可以直接apt安装需要的软件。
