Ubuntu22.04でのMineOS環境構築

Last updated at Posted at 2022-12-24

初めに

MineOSというMineCraftサーバー管理ツールをご存じでしょうか？
WebUI上からサーバーの新規作成、起動、停止、定期バックアップなどいろいろできる便利ツールです。
昔から利用しているのですが毎回構築するたびにやり方を忘れるのでメモ程度に手順を残しておきます。

以下公式サイト
https://wiki.codeemo.com/

環境

今回はESXi8.0上のVMに構築

項目 詳細
OS Ubuntu22.04LTS
CPU 6vCPU
RAM 30GB
Storage SAS HDD 100GB

構築

基本的には公式ドキュメント通りに進める

UbuntuOSのインストール

Node.jsのインストール

NodeJSのサイトを参照しつつ

Javaのインストール

ここは構築したいサーバーのバージョンに対応したJavaのインストールが必要
今回はMinecraft1.19のサーバーを構築したいのでJava17をインストール
バージョンの対応は下記サイトがまとめてくれています
https://mcpoteton.com/mcserver/official-server#index_id5

怒られた
nodejsは何も分からないので調べたサイトと結果だけ書きます。

参考：https://qiita.com/zaburo/items/12f99aa07ab934d07d75#%E3%81%82%E3%82%8B%E3%83%A2%E3%82%B8%E3%83%A5%E3%83%BC%E3%83%AB%E3%81%A7%E3%82%A8%E3%83%A9%E3%83%BC

rootユーザーで--unsafe-permを付けたらとりあえず実行できました。

root@localhost:/usr/games/minecraft# npm install --unsafe-perm

が、いろいろ動いていない気がする。

ざっと確認したところ、

  • 稼働率グラフ
  • プロファイルダウンロードページ
  • 表示言語変更
  • 新規サーバー作成

辺りが動いていない模様

トラブルシューティング

トラブルシューティングページを参考に
https://wiki.codeemo.com/maint/webui.html

上記ページを参考に下記を実行

# cd /usr/games/minecraft
# git fetch
# git reset --hard origin/master
# git checkout master
# rm -rf ./node_modules
# npm install --unsafe-perm

sudoではなくルートユーザーでnpm install --unsafe-permを実行したら成功しました。

まとめ

現行OSのUbuntu22.04での構築記事がどこにもなかったためかなり手探りな状態でしたがなんとか構築できたのでよかったです。ただNodeJSで脆弱性がなんとかってメッセージが出ていたりとガバガバな部分もあるので細かい部分の設定もこれから修正が必要そうな感じです。途中npmなんもわからんって言ってたのでもっと勉強しようと思いました。

最後に、ドキュメントはしっかり読もう。
