摘自 Wikipedia:Virtual private server:

  Virtual private server (VPS) is a term used by Internet hosting services to refer to a virtual machine. The term is used for emphasizing that the virtual machine, although running in software on the same physical computer as other customers' virtual machines, is in many respects functionally equivalent to a separate physical computer, is dedicated to the individual customer's needs, has the privacy of a separate physical computer, and can be configured to run server software.

本文主要讨论Arch Linux在VPS方面的应用, 并且包括了一些VPS的详细的安装于维护的指南.

警告: systemd从版本205开始就不再支持Linux 2.6.32了(system-212或更高的版本也不行). 因为很多基于容器的虚拟环境依赖较老版本的内核, 在这样的环境下想要保证Arch Linux 随时都是最新版本是不现实的. 然而截止kernel build 042stab094.7, OpenVZ已经对 CLOCK_BOOTTIME 特性进行了backport, 并且现在他可以和最新的systemd一起正常运行.

## 支持Arch Linux的提供商

警告: 我们无法为提供商的质量与诚信做担保. 请在下订单前自行进行调查.
注意: 这个列表只列出了那些提供便捷的Arch Linux模板的提供商. 在其他提供商的环境中试用Arch Linux仍然是可行的, 只是相比之下需要更多的工作. 比如我们可以加载自定义的光盘映像 (这需要硬件层面的虚拟化, 比如Xen or KVM), installing under chroot, 或者 using rsync to synchronize Arch over the top of another distribution.

### OpenVZ

#### 在任意OpenVZ提供商上安装Arch Linux

警告: 阅读 最上的警告[broken link: invalid section] 来了解关于较老版本内核和systemd的相关信息.

It's possible to directly copy an installation of Arch Linux over the top of a working OpenVZ VPS. This tutorial explains how to create a basic installation of Arch Linux with `pacstrap` (as used in a standard install) and then replace the contents of a target VPS with it using rsync.

This process (with minor modification) also works to migrate existing Arch installations between various environments and has been confirmed to work in migrating from OpenVZ to Xen and from Xen to OpenVZ. For an install to Xen, other hardware-virtualized platforms, or probably even to physical hardware (unconfirmed), extra steps (basically running `mkinitcpio` and installing a bootloader) are needed.

##### 前置知识

- A working Arch Linux installation
  - To keep things simple, it should match the architecture you want to install on your VPS (x86_64 or i686).
  - To build from other distributions, arch-bootstrap.sh can be used in place of `pacstrap`.
- The arch-install-scripts, rsync, and openssh packages from the official repositories
  - SSH isn't strictly required, but rsync over SSH is the method used here.
- A VPS running any distribution, with `rsync` and a working SSH server
  - Its architecture (x86_64 or i686) doesn't matter as long as the OpenVZ installation can support your target architecture.
- OpenVZ's serial console feature (usually accessible via your provider's control panel)
  - Without this, any network configuration for the target VPS will have to be done immediately after the "Build" step below.

##### 搭建一个干净的Arch Linux

As root, build the installation (optionally replacing `build` with your preferred target directory):

    # mkdir build
    # pacstrap -cd build

Other tweaks for the `pacstrap` command:

- `-C custom-pacman-config.conf` - Use a custom pacman configuration file. By default, pacstrap builds according to your local pacman.conf. This determines the architecture (i686 or x86_64) of the build, the mirror list, etc.
- `-B` - Prevent pacstrap from copying your system's pacman keyring to the new build. If you use this option, you'll need to run `pacman-key --init` and `pacman-key --populate archlinux` in the Configuration step to set up the keyring.
- `-M` - Prevent pacstrap from copying your system's pacman mirror list to the new build.

##### 把VPS上的所有东西都Arch Arch掉

把目标VPS上所有的文件, 目录和其它各种东西都用你的`build`目录的内容替换掉 (把下面的 "YOUR.VPS.IP.ADDRESS" 换掉):

警告: 处理下面的命令的时候当心点. `rsync`这个命令根据设计就是极具毁灭性的, 特别是带上 `--delete` 选项的时候.

    # rsync -ax --delete-delay -e ssh --stats -P build/ YOUR.VPS.IP.ADDRESS:/

选项的解释:

At minimum, only the `-a` (preserve timestamps, permissions, etc.), `-x` (don't cross filesystem boundaries), and `--delete` (delete anything in the target that doesn't exist in the source) options are required. The `--delete-delay` option is an alternate deletion mode which waits to delete anything until the synchronization is otherwise complete; this isn't necessary but may reduce the risk of a slow transfer causing the target VPS to lock-up. The `-e ssh` (use rsync over SSH) option is recommended and makes things simple. The `--stats` and `-P` options are just to show more information.

##### 配置

1. 将VPS从外部重启 (比如你可以利用provider的控制面板来干这件事).
2. 使用 OpenVZ 的端口控制特性来配置 网络 和 基本系统设定 (无视 fstab 的生成和 arch-chroot 的相关步骤).
   - 如果你接触不到端口控制特性, 那你在把Arch Linux同步到VPS前就提前配置好你的网络设定.
