问题是，它在启动时无法运行，这很奇怪，因为当我之后输入时sudo service minecraft start它没有任何问题”。我显然做到了
sudo update-rc.d minecraft defaults
问题是什么，或者我怎样才能至少获得一些日志
答案1
假设您正在使用基于 upstart 的 ubuntu 版本，请尝试：
sudo update-rc.d minecraft enable
Upstart 日志存储在 /var/log/upstart/* 中，如果上述方法不起作用，您可以在那里检查。
答案2
一个选择是编写一个稍微不太复杂的脚本并从以下位置启动它/etc/rc.local：
bash /home/username/minecraft.sh &> /dev/null &
如果您无法让服务正常运行，这是一个选项/替代方法。
