Ich habe ein sehr seltsames Verhalten in Tomcat 7 unter Ubuntu 14.04.
Ich habe ein neues VPS erstellt, default-jdk und andere einfache Dinge installiert. Heruntergeladene und entpackte Tomcat 7. Überprüfte, ob sie ausgeführt wird [myIP]:8080
, und sah die Indexseite von Tomcat.
Nach dem Neustart des VPS habe ich Tomcat erneut gestartet und ... es erfolgt keine Antwort [myIP]:8080
. Nicht einmal ein Fehler. Als ich die Protokolle überprüfte, stellte ich fest, dass Tomcat in der ersten Webanwendung nur im Bereitstellungszustand hängt.

Bis Zeile 74 ist dies ein normaler Serverstart. Alle Standard-Webanwendungen wurden bereitgestellt (Zeilen 48-68), aber danach hängt es nur noch. Also habe ich den Server gestoppt und mein System neu gestartet. Tomcat wieder gestartet, und das Wunder beginnt. Die nächste Sitzung findet in den Zeilen 89-136 statt, und Sie können sehen, dass dort kein Eintrag für vorhanden ist Server startup in xxxx ms
.
Es hängt nur im Einsatz und diese Situation wiederholt sich ständig. Was könnte das verursachen? Ich habe Stunden damit verbracht, mit diesem Problem zu kämpfen, und ich werde verrückt und komme nirgendwo hin.

Antworten:
Ein mögliches Problem ist, dass Tomcat darauf wartet, dass sich Entropie aufbaut. Nehmen Sie ein paar Thread Dump mit, um
jstack
zu sehen, wer auf was wartet.Tomcat 7+ ist stark auf die
SecureRandom
Klasse angewiesen , um zufällige Werte für seine Sitzungs-IDs und andere Dinge bereitzustellen. Abhängig von Ihrer JRE kann es beim Start zu Verzögerungen kommen, wenn die zur Initialisierung verwendete Entropiequelle nicht ausreichend entropischSecureRandom
ist.Wenn das Problem Entropie ist, können Sie JRE so konfigurieren, dass eine nicht blockierende Entropiequelle verwendet wird, indem Sie die folgende Systemeigenschaft festlegen:

, Feeds / dev / random mit Entropie zu installieren , siehe digitalocean.com/community/tutorials/…Kann für jemanden hilfreich sein:
Überprüfen Sie, ob Ihre pom.xml KEINE solchen Abhängigkeiten enthält:

Eine mögliche Ursache für das Problem: Ein Tippfehler im Pfad der Keystore-Datei:
