私は何をしたいですか？
最近、ローカルネットワークのサーバーとして使用するコンピュータにNixOSを設定しました。 nginxをhttpサーバーとして使用したいです。
私が試したこと
nginxファイルを/etc/nixos/configuration.nixEnvironment.systempackagesセクション以下に配置しましたservices.nginx.enable=true。ファイアウォールも無効になっています。ブラウザにサーバーのIPアドレスを入力すると、Webサービスは実行されていません。nginx端末に入力すると、次の結果が表示されます。
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()
これはその後も発生しますsudo fuser -k 80/tcp。私もこれを追加しようとしました。
services.nginx = {
enable = true;
recommendedProxySettings = true;
recommendedTlsSettings = true;
virtualHosts."localhost" = {
locations."/var/html/".proxyPass = "http://localhost:8000";
};
appendHttpConfig = "listen 127.0.0.1:80";
};
私のnixos設定（一部の行コメントを含む）ですが、実行時のnixos-rebuild switch出力は次のようになります。
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.

私はNixOSに初めて接して基本的なミスをしているのかもしれませんが、どうすればいいですか？

問題は、49行目を見ると次のようなことです。
listen 127.0.0.1:80
行の最後に;これが欠けていることがわかります。それが問題だ。 Configuration.nix ファイルを見ると、次のことがわかります。
appendHttpConfig = "listen 127.0.0.1:80";
;行末に追加できませんでした。次のように変更してみてください。
appendHttpConfig = "listen 127.0.0.1:80;";
これにより問題が解決します。
