サーバーにtomcat7がインストールされています。その中に 1 つのアプリケーションがあります。これで、アプリケーションがクラッシュします。ログインしようとすると、セッションが作成されません。そこでtemp、TOMCAT7のホームフォルダ配下のファイルを削除しようと考えています。

今、私の質問は、

  1. 一時フォルダーを削除しても安全ですか?
  2. 削除後、何か問題はありますか？

ここにログがありますcatalina.log

別のアプリがポートを使用しているようです。アプリがすでにポートにバインドされている場合、別のアプリが同じポートを使用/バインドすることはできません。どのアプリがそのポートにバインドされているかを確認します。これを試して：

netstat -ntl | grep :8080

どのプロセスがすでに8080を使用しているかを確認します。

Tomcatのポートを変更する場合は、ディレクトリTOMCAT_HOME \ confのファイルserver.xmlを確認します。ポートアドレスが表示されます。8080の場合は、8081などに変更してサーバーを起動し、localhost：8081を押して確認します。

server.xmlでは、コードは次のようになります。

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />

さらに、どのプロセスがポートを使用しているかを知りたい場合は、次のプロセスを試してください。

netstat -aon | findstr 0.0:8080

これにより、最後の列にプロセスIDが表示されます。次に、タスクマネージャーから、そのプロセスIDを持つプロセスを見つけます。そうすれば、どのプロセスがそのポートを使用しているかがわかります。
