Não é possível iniciar o tomcat depois de instalá-lo no Ubuntu 16.04: “O trabalho para o tomcat.service falhou porque o processo de controle foi encerrado com o código de erro.”

Question

Eu segui os passos link para instalar o tomcat 8.5.24 no Ubuntu 16.04, até executar sudo ufw allow 8080 em "Etapa 6: ajustar o firewall e testar o servidor Tomcat".

Então não consigo iniciar o tomcat,

$ sudo systemctl start tomcat
Job for tomcat.service failed because the control process exited with error code. See "systemctl status tomcat.service" and "journalctl -xe" for details.

e o link http://localhost:8080/ não funciona nos navegadores firefox e google chrome.

Eu queria saber como resolver o problema.

Os detalhes a seguir são o que eu segui as mensagens de saída acima de sudo systemctl start tomcat . Parece que /opt/tomcat/bin/startup.sh foi bem-sucedido enquanto /opt/tomcat/bin/shutdown.sh falhou. Muito agradeço sua ajuda!

update:

Em vez de sudo systemctl start tomcat , que indica o erro acima, se eu executar

cd /opt/tomcat/bin

sudo ./catalina.sh run

O

link mostra a página da Web correta. Então, qual é a razão pela qual um não funciona enquanto o outro faz?

    

Answer 1

Aconteceu comigo também. O que ajudou foi excluir este arquivo: /opt/tomcat/temp/tomcat.pid

Este é um arquivo temporário criado pelo tomcat na inicialização. Aparentemente, se existir por algum motivo, o serviço não será iniciado. -
