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

  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。
