如何在archlinux上安装RPM包

有时候你可能会发现,想安装一个包,但是这个包只提供RPM安装文件,而archlinux并不支持安装RPM文件,这该怎么办呢?

下面这个方法也许可以帮到你

  1. 安装 rpmextract

    rpmextract 是一个用来解压 rpm 的工具,它会将rpm包中的内容解压到当前目录下。

    sudo pacman -S rpmextract --noconfirm

    Packages (1) rpmextract-1.0-8

  2. 使用rpmextract解压rpm文件

    由于rpm文件中打包的目录结构是以根目录为基准的,因此推荐直接在根目录下进行解压:

    cd /
    sudo rpmextract.sh ~lujun9972/android-x86-7.1-r2.x86_64.rpm
    
  3. 抽取出安装RPM时调用的脚本

    光把RPM包中的文件解压出来还是不够的,rpm文件在安装(或者卸载)前/后还会执行一个脚本。

    这个脚本可以通过命令 rpm -qp --script file.rpm 来查看。

    然而, archlinux 并没有rpm命令怎么办呢?我们可以可以在虚拟机上运行一个 centos 或者直接使用docker来模拟一个 centos 环境也可以:

    docker run --rm -v ~lujun9972/android-x86-7.1-r2.x86_64.rpm:/tmp/android.rpm centos rpm -qp --scripts /tmp/android.rpm
    
    postinstall scriptlet (using /bin/sh):
    . /etc/os-release
    mkdir -p /android-7.1-r2/data
    if [ "$ID" = "debian" -o "$ID_LIKE" = "debian" ]; then
      grubcfg=/boot/grub/custom.cfg
    elif mountpoint -q /boot/efi; then
      grubcfg=/boot/efi/EFI/$ID/custom.cfg && efi=efi
    else
      grubcfg=/boot/grub2/custom.cfg
    fi
    echo -e "menuentry \"Android-x86 7.1-r2\" {\n\tsearch --set=root --file /android-7.1-r2/kernel\n\tlinux$efi /android-7.1-r2/kernel quiet root=/dev/ram0 androidboot.selinux=permissive buildvariant=userdebug \n\tinitrd$efi /android-7.1-r2/initrd.img\n}" > $grubcfg
    echo -e "menuentry \"Android-x86 7.1-r2 (DEBUG mode)\" {\n\tsearch --set=root --file /android-7.1-r2/kernel\n\tlinux$efi /android-7.1-r2/kernel root=/dev/ram0 androidboot.selinux=permissive buildvariant=userdebug DEBUG=2\n\tinitrd$efi /android-7.1-r2/initrd.img\n}" >> $grubcfg
    
    if [ "$ID" = "debian" -o "$ID_LIKE" = "debian" ]; then
      sed -i 's/^GRUB_HIDDEN_/#GRUB_HIDDEN_/' /etc/default/grub
      update-grub
    fi
    postuninstall scriptlet (using /bin/sh):
    . /etc/os-release
    if [ "$ID" = "debian" -o "$ID_LIKE" = "debian" ]; then
      grubcfg=/boot/grub/custom.cfg
    elif mountpoint -q /boot/efi; then
      grubcfg=/boot/efi/EFI/$ID/custom.cfg
    else
      grubcfg=/boot/grub2/custom.cfg
    fi
    if [ "$1" = "1" ]; then
      new_prefix=`dirname $(grep initrd $grubcfg | head -1 | awk '{print $2}')`
      if [ "$new_prefix" != "/android-7.1-r2" ]; then
        rmdir $new_prefix/data
        mv /android-7.1-r2/data $new_prefix
        rmdir /android-7.1-r2
      fi
    else
      rmdir /android-7.1-r2/data /android-7.1-r2
      rm -f $grubcfg
    fi
    
  4. 调用安装脚本,运气好的话,你就能把rpm安装好了。
