VPS上のLinuxのユーザー空間にArch Linuxの環境を構築する話(2)

はじめに

まあまずは
VPS上のLinuxのユーザー空間にArch Linuxの環境を構築する話 — 173210's Blog
をみてもらうとして、これをmsys2上からやるときにどうするかという問題がある。

とりあえずそのままでは動かないので手順を書いておく。なおprootはサーバー管理者が上記記事のように入れてくれていることを前提にする。

msys2上での作業

まずこんなファイルを適当な場所に作っておく。

%echo Generating pacman keyring master key...
Key-Type: RSA
Key-Length: 2048
Key-Usage: sign
Name-Real: Pacman Keyring Master Key
Name-Email: pacman@localhost
Expire-Date: 0
%no-protection
%commit
%echo Done
EOF

次に秘密鍵を生成してサーバーに転送する。

$gpg --homedir gnupg --gen-key --batch < tmp.txt
$tar cf gnupg.tar gnupg
$scp -P 110 gnupg.tar yumetodo@kagucho.net:

VPN上での作業

まずはbootstrap用imageを落としてくる。

bootstrap用イメージはArch Linux - Downloadsからテキトーなミラーのリンクを踏めば見つかる. 試しにftp.tsukuba.wide.ad.jpに行ってみると無造作にファイルが置かれた中にarchlinux-bootstrap-2016.11.01-x86_64.tar.gzがあるのでこれを使う.
$ cd ~
$ wget http://ftp.tsukuba.wide.ad.jp/Linux/archlinux/iso/2016.11.01/archlinux-bootstrap-2016.11.01-x86_64.tar.gz -O - | tar xz

proot上のpacman用のmirrorlistを編集する。すでに用意されているmirrorlistのうち近そうなサーバーのコメントアウト(#)を外せば良い。もちろんテキストエディタは好きなものを使えば良い。nanoの場合はCtrl+OEnterすれば保存、Ctrl+Xで終了だ。

$ nano root.x86_64/etc/pacman.d/mirrorlist

先程転送した秘密鍵を展開する。

$ tar -C root.x86_64/etc/pacman.d -xf gnupg.tar

準備が整ったのでprootでArch Linuxを開始するのだが、起動コマンドが長すぎてやってられないので、aliasを貼る。.bashrc

alias 'archlinux=proot -0 -b /etc/resolv.conf -m /dev -m /sys -m /proc -w / -r root.x86_64'

としておく。.bashrcを反映するためにsshし直すとかなんかして、

archlinux

で起動する。

proot上での作業

まずはgpgの初期化をする。

# pacman-key --init
# pacman-key --populate archlinux

さて、ここまでくればmsys2ユーザーにとっては日常だ。

# pacman -Syuu
# pacman -S base-devel git clang openmp gdb lldb

しばらく時間がかかるので放置したのち、動作確認だ。

いいね。

余談

どういうわけかどこの.bashrcも読み込んでくれないようなのので、root.x86_64/etc/bash.bashrc

source "${HOME}/.bashrc"

を追加するといいかもしれない。msys2で使っていたものがほぼそのまま使える。例えば

export PS1='\[\e]0;\w\a\]\n\[\e[32m\]\u@\h \[\e[m\]\[\e[36m\]\w\[\e[m\]\[\e[0m\]\n$'

とか書いて置くと見た目がきれいでいい。
