平台： ubuntu-22.04-desktop-amd64.
对象： ubuntu base、qemu.
文件： ubuntu-base-22.04.2-base-arm64.tar.gz、linux-6.1.26.tar.xz
Ubuntu Base不是一个超小的内存运行嵌入式发行版;它是Ubuntu的最小实现，本例通过qemu运行ubuntu-base.
1.安装依赖
$ sudo apt install binfmt-support qemu-user-static qemu-system-aarch64 gcc-aarch64-linux-gnu
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]
ubuntu-base-22.04.2-base-arm64.tar.gz
[http://cdimage.ubuntu.com/ubuntu-base/releases/22.04.2/release/ubuntu-base-22.04.2-base-arm64.tar.gz]
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=ubuntu22-base.ext4 bs=1M count=1024 $ mkfs.ext4 ubuntu22-base.ext4 $ sudo mount -t ext4 ubuntu22-base.ext4 /mnt/ $ sudo tar -xf ubuntu-base-22.04.2-base-arm64.tar.gz -C /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
5.chroot
$ sudo chroot /mnt
进入chroot环境：
$ apt update $ apt install systemd sudo rsyslog resolvconf udev vim $ useradd -s '/bin/bash' -m -G adm,sudo phoebus $ passwd phoebus $ echo "ubuntu22" > /etc/hostname $ cp /lib/systemd/system/serial-getty\@.service /lib/systemd/system/serial-getty\@ttyAMA0.service
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
然后执行：
$ systemctl enable serial-getty\@ttyAMA0.service $ exit
退出chroot之后，执行：
$ 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 $ vim start-qemu.sh
填入如下内容：
#!/bin/sh
qemu-system-aarch64 \
-M virt \
-cpu cortex-a53 \
-nographic \
-smp 1 \
-m 512M \
-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=ubuntu22-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。
