Minecraft Server (統合版) をsystemdによる自動起動設定
概要
- Minecraft BedrockサーバをLinux上で起動させてSystemd配下でサービスを管理する設定。
- Minecraft bedrockサーバはしばらく立ち上げておくとメモリを食いすぎて勝手に落ちてしまいます。勝手に落ちたら手動で起動をするのが面倒なので systemd配下で管理して勝手に再起動をするように設定します。
設定内容
以下のREADMEに書いてあるコマンドの流れで設定します。
bedrock.serviceファイルのUserやbedrockサーバの実行バイナリが置いてある場所は各自の内容に置き換えてください。
備考
以下のサイトに紹介されている方法は余計なことが色々書いてあり、あまり使いたくなかったため自分で書きました。
