进入 救援模式后,我们输入以下命令查看具体磁盘名字:

1
fdisk -l

会出现类似于图示:

磁盘最大的那块就是主磁盘,我们这里是/dev/vda,记住这个磁盘。

开始安装:

下面 /dev/vda部分请替换为上面fdisk查出来的磁盘信息!

  1. 格式化分区(遇到提示,输入y确定)
    1
    mkfs.ext4 /dev/vda
  2. 去掉ext4的64bit,因为引导syslinux不支持
    1
    resize2fs -s /dev/vda
  3. 创建目录并挂载
    1
    mkdir /mnt/custom;mount /dev/vda /mnt/custom/
  4. 下载 alpine linux apk tools(无法下载请谷歌搜索此文件apk-tools-static-2.10.4-r3.apk进行寻找)
    1
    apt update;apt install wget -y;wget https://mirror.netcologne.de/alpine/edge/main/x86/apk-tools-static-2.10.4-r3.apk
  5. 解压
    1
    tar xzvf apk-tools-static-2.10.4-r3.apk
  6. 安装alpine linux
    1
    ./sbin/apk.static -X http://dl-cdn.alpinelinux.org/alpine/latest-stable/main -U --allow-untrusted --root /mnt/custom/ --initdb add alpine-base
  7. 复制文件resolv.conf,解析域名
    1
    cp /etc/resolv.conf /mnt/custom/etc/
  8. 创建用户 root 目录
    1
    mkdir -p /mnt/custom/root
  9. 创建 apk 配置目录
    1
    mkdir -p /mnt/custom/etc/apk
  10. 设置apk更新镜像网址
    1
    echo "http://dl-cdn.alpinelinux.org/alpine/latest-stable/main" > /mnt/custom/etc/apk/repositories
  11. 创建相应设备目录:
    1
    2
    3
    4
    5
    6
    mknod -m 666 /mnt/custom/dev/full c 1 7
    mknod -m 666 /mnt/custom/dev/ptmx c 5 2
    mknod -m 644 /mnt/custom/dev/random c 1 8
    mknod -m 644 /mnt/custom/dev/urandom c 1 9
    mknod -m 666 /mnt/custom/dev/zero c 1 5
    mknod -m 666 /mnt/custom/dev/tty c 5 0
  12. 挂载目录
    1
    2
    3
    mount -t proc none /mnt/custom/proc
    mount -o bind /sys /mnt/custom/sys
    mount -o bind /dev /mnt/custom/dev
  13. chroot 到 apline 文件所在目录
    1
    chroot /mnt/custom /bin/sh -l
  14. 创建IP配置文件(可以使用原VPS的/etc/network/interfaces文件)
  15. 安装openssh
    1
    setup-sshd
  16. 开启root登陆,并修改root密码
    1
    2
    sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/g' /etc/ssh/sshd_config
    passwd
  17. 添加普通用户liujia,以可远程登录
    1
    adduser liujia -s /bin/ash
  18. 将用户添加到wheel组,可使用su
    1
    addgroup liujia wheel
  19. 设置可启动的服务

    rc-update add devfs sysinit
    rc-update add dmesg sysinit
    rc-update add mdev sysinit
    rc-update add hwclock boot
    rc-update add modules boot
    rc-update add sysctl boot
    rc-update add hostname boot
    rc-update add bootmisc boot
    rc-update add syslog boot
    rc-update add mount-ro shutdown
    rc-update add killprocs shutdown
    rc-update add savecache shutdown
    rc-update add networking boot
    rc-update add urandom boot
    rc-update add acpid default
    rc-update add hwdrivers sysinit
    rc-update add crond default
  20. 安装内核和引导
    1
    apk add linux-vanilla syslinux
  21. 将mbr引导写到磁盘中
    1
    dd bs=440 count=1 if=/usr/share/syslinux/mbr.bin of=/dev/vda
  22. 查看具体boot分区,方便第23步使用:
    1
    extlinux -i /boot
  23. 查看设备uid,请把/dev/vda路径替换为22步获取的路径,并记录下显示的UUID信息
    1
    blkid /dev/vda
  24. 将磁盘uuid写到启动配置文件中,务必替换自己的UUID值,UUID后的:要保留!*
    1
    sed -i -e "s:^root=.*:root=UUID=bb5b133e-4702-4c3b-b6ae-66cde61cf27a:" /etc/update-extlinux.conf
  25. 添加 ext4支持
    1
    sed -i -e "s:^modules=.*:modules=sd-mod,usb-storage,ext3,ext4:" /etc/update-extlinux.conf
  26. 更新引导配置
    1
    update-extlinux
  27. 将磁盘信息写到文件系统配置文件中,UUID替换为自己的
    1
    echo "UUID=66ea5797-490e-4cf5-8743-61525af5bfbc / ext4 defaults 1 1" > /etc/fstab
  28. 关闭rescue模式,静等vps开机
