Setting Up a Minecraft Bedrock Edition Server on OpenSUSE
はじめに
以前わたしがOracleCloudでマイクラサーバーを作成していたのですが、その時に自動で最新バージョンにアップデート・バックアップを取ってくれる便利なスクリプトがあったことを思い出し探してみました。
ネットの海を探して探してやっと見つけました。
https://jamesachambers.com/minecraft-bedrock-edition-ubuntu-dedicated-server-guide/
これでいざ実装しようかと思った時に、私のサーバーがUbuntuではなく、OpenSUSEで作成していることに気づきましたが、少し修正すれば動くんじゃないかなと思い行ってみました。
１．パッケージマネージャーの変更
パッケージマネージャーをUbuntuのaptからOpenSUSE用のzypperに変更しました。
それに伴ってパッケージ名をnet-tools → net-tools-deprecated、libcurl4、libopenssl1_1 に変更しています。
sudo zypper refresh
sudo zypper update -y
sudo zypper install -y curl unzip screen net-tools-deprecated gawk openssl pigz libcurl4 libopenssl1_1２．Arm対応部分・不要部分の削除
ARM アーキテクチャ向けの設定を簡略化し、box64 のインストールに関する部分を削除しています。
他にも要らないと思われる部分を削除しました。
３．依存関係チェックの簡略化
Ubuntu 向けの詳細な依存関係チェックを削除し、OpenSUSE 向けにシンプル化しました（ほぼ消しただけ）。
４．サーバーダウンロード部分の変更
downloads/version.htmlをみたときに、そこの部分が上手く機能していなかったみたいなので修正しました。
DownloadURL=$(grep -o 'https://www.minecraft.net/bedrockdedicatedserver/bin-linux/[^"]*' downloads/version.html)start.shも同じようにURL部分をhttps://www.minecraft.net/bedrockdedicatedserver/bin-linuxから参照するように変更する必要があります。
それに伴ってupdate.shも以下のようにクローンした部分から編集したものを使用するようにしました。

実際に修正済みのコードはこちらです。

この方のおかげでマインクラフトに関しての管理が大変楽になったので、感謝しています。
同じように悩んでいらっしゃる方がいれば、参考になれば幸いです。
