Tomcat7 trava na implantação de aplicativos

9

Estou tendo um comportamento muito estranho no Tomcat 7 no Ubuntu 14.04.

Criei um novo VPS, instalei o default-jdk e outras coisas simples. Tomcat baixado e descompactado 7. Verifique se ele é executado [myIP]:8080e veja a página de índice do Tomcat.

Depois de reiniciar o VPS, iniciei o Tomcat novamente e ... não há resposta [myIP]:8080. Nem mesmo um erro. Quando verifiquei os logs, vi que o Tomcat fica travado no estado de implantação no primeiro aplicativo da web.

Meus logs :

Até a linha 74, esta é uma inicialização normal do servidor. Todos os aplicativos da web padrão foram implantados (linhas 48-68), mas depois disso apenas travaram. Então, parei o servidor e reinicializei meu sistema. Iniciou o tomcat novamente e o milagre começou. A próxima sessão está nas linhas 89-136 e você pode ver que não há entrada para Server startup in xxxx ms.

Ele simplesmente trava na implantação e essa situação se repete o tempo todo. O que poderia estar causando isso? Passei horas lutando com esse problema e estou ficando louco e não chego a lugar nenhum.

Eu encontrei uma boa decisão aqui. Precisamos atualizar o gerador aleatório de daemon, que suportará nosso sistema com enthropy. stackoverflow.com/questions/27612209/…

Um possível problema é o Tomcat aguardando a construção da entropia. Dê uma olhada em alguns tópicos jstackpara ver quem está esperando o quê.

O Tomcat 7+ depende muito da SecureRandomclasse para fornecer valores aleatórios para seus IDs de sessão e outras coisas. Dependendo do seu JRE, isso pode causar atrasos durante a inicialização, se a fonte de entropia usada para inicializar SecureRandomtiver pouca entropia.

Se o problema for entropia, existe uma maneira de configurar o JRE para usar uma fonte de entropia sem bloqueio, configurando a seguinte propriedade do sistema: 

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

Veja esta discussão relacionada para mais detalhes .

INFO: A criação da instância SecureRandom para geração de ID da sessão usando [SHA1PRNG] levou [4.118.269] milissegundos. Parece que você está certo. Vou tentar mudar a fonte de entropia
— Asprelis
Oh Deus, obrigado pela dica !!! Estou preocupado com esse problema por cerca de 2 dias!
— Rugal
Uma solução alternativa é a instalação havegedque feeds / dev / random com a entropia, consulte digitalocean.com/community/tutorials/...

@ James sim, é claro, mas você deve cuidar dos detalhes security.stackexchange.com/questions/34523/…

Pode ser útil para alguém:

Verifique se você NÃO possui tais dependências no seu 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>

Você poderia explicar o porquê? Eu tenho essas dependências em um dos meus projetos. e tudo parece bem.

Uma possível causa do problema: um erro de digitação no caminho do arquivo keystore:

keystoreFile="conf/cert/certificate.ks"
— Olivier Faucheux

isso pode realmente acontecer, e você pode ignorar o erro durante o processo de carregamento do servidor
