VNCサーバーを起動できません：構成されたリソース制限を超えました

VNCサービスは、最近の停電まで正常に機能していました。

走ろうとすると

systemctl start vncserver@:1.service

それはメッセージを与える

Job for vncserver@:1.service failed because a configured resource limit was exceeded. See "systemctl status vncserver@:1.service" and "journalctl -xe" for details.

そして私が走るとき

systemctl status vncserver@:1.service

次の出力が得られます

この問題を解決するにはどうすればよいですか？

私は解決策を見つけました：ファイルを削除しますX1 via rm -f /tmp/.X11-unix/X1およびVNCサーバーの再起動が機能しました。

受け入れられた回答に記載されているように、残りのソケットファイルの削除を自動化するために、この/etc/systemd/system/[email protected]ファイルを作成しました。

元の設定との主な違い：

  • 次のステップでコロンを取り除く必要があるため、systemd指定子%iの値を環境変数display_tempとして保存します（:1-> 1）
  • vncserver -killの後、/tmp/.X11-unix/ディレクトリの下のソケットを削除し、/tmp/のファイルをロックします。環境変数置換を使用するには、次のようにドル記号をエスケープする必要があります：$$（詳細についてはその回答を参照してください： https://unix.stackexchange.com/a/216786 ）
