Tomcat7 si blocca sulla distribuzione di app

10

Sto avendo un comportamento molto strano in Tomcat 7 su Ubuntu 14.04.

Ho creato un nuovo VPS, installato default-jdk e altre cose semplici. Tomcat scaricato e decompresso 7. Controllato che funzioni [myIP]:8080e ha visualizzato la pagina indice di Tomcat.

Una volta riavviato il VPS, ho riavviato Tomcat e ... non c'è risposta [myIP]:8080. Neanche un errore. Quando ho controllato i registri, ho visto che Tomcat si blocca in stato di distribuzione sul primo webapp.

I miei registri :

Fino alla linea 74, si tratta di un normale avvio del server. Sono state distribuite tutte le webapp standard (linee 48-68), ma dopo si blocca. Quindi, ho fermato il server e riavviato il mio sistema. Ha ricominciato Tomcat e inizia il miracolo. La sessione successiva è nelle righe 89-136 e puoi vedere che non ci sono voci per Server startup in xxxx ms.

Si blocca solo nella distribuzione e questa situazione si ripete continuamente. Che cosa potrebbe causare questo? Ho passato ore a lottare con questo problema e impazzisco e non vado da nessuna parte.

Ho trovato una buona decisione qui. Dobbiamo aggiornare il generatore casuale di demoni, che supporterà il sistema operativo con enthropy. stackoverflow.com/questions/27612209/...

Un possibile problema è Tomcat in attesa di accumulo di entropia. Prendi un po 'di discarica con jstackper vedere chi sta aspettando cosa.

Tomcat 7+ si affida fortemente alla SecureRandomclasse per fornire valori casuali per i suoi ID di sessione e altre cose. A seconda del JRE, può causare ritardi durante l'avvio se la sorgente di entropia utilizzata per inizializzare SecureRandomè a corto di entropia.

Se il problema è l'entropia, esiste un modo per configurare JRE in modo che utilizzi un'origine entropia non bloccante impostando la seguente proprietà di sistema: 

-Djava.security.egd=file:/dev/./urandom

Vedi questa discussione correlata per maggiori dettagli .

INFORMAZIONI: La creazione dell'istanza SecureRandom per la generazione dell'ID sessione mediante [SHA1PRNG] ha richiesto [4.118.269] millisecondi. Sembra che tu abbia ragione. Proverò a cambiare la fonte dell'entropia
— Asprelis il
Oh dio grazie per il suggerimento !!! Sono turbato da questo problema per circa 2 giorni!
— Rugal,
Una soluzione alternativa è l'installazione di havegedfeed / dev / random con entropia, vedi digitalocean.com/community/tutorials/…

Può essere utile per qualcuno:

Verifica di non avere tali dipendenze nel tuo pom.xml:

    <dependency>
        <groupId>org.apache.tomcat.maven</groupId>
        <artifactId>tomcat7-maven-plugin</artifactId>
        <version>2.2</version>
    </dependency>

    <dependency>
        <groupId>org.apache.tomcat</groupId>
        <artifactId>tomcat-catalina</artifactId>
        <version>8.0.23</version>
    </dependency>

Potresti spiegare perché? Ho tali dipendenze in uno dei miei progetti. e tutto sembra a posto.

Una possibile causa del problema: un errore di battitura nel percorso del file keystore:

keystoreFile="conf/cert/certificate.ks"
— Olivier Faucheux
fonte
questo potrebbe effettivamente accadere e potresti trascurare l'errore durante il processo di caricamento del server
