O problema é que ele não roda na inicialização, o que é estranho porque quando eu digito depois o sudo service minecraft start
não funciona ". Eu obviamente fiz
sudo update-rc.d minecraft defaults
O que parece ser o problema ou como posso pelo menos obter alguns registros
Supondo que você está usando uma versão do ubuntu baseada em upstart, tente:
sudo update-rc.d minecraft enable
Upstart logs são armazenados em / var / log / upstart / * você pode verificar lá se o acima não funcionar.
Uma opção é escrever um script um pouco menos complicado e iniciá-lo em /etc/rc.local
:
bash /home/username/minecraft.sh &> /dev/null &
Esta é uma opção / método alternativo se você não conseguir que o serviço funcione.
