开始使用Puppet Learning VM后，我第一次尝试安装puppet。我的问题是我无法让PuppetDB作为服务启动，而且我找不到足以表明任何问题的错误消息。 （session_token）
然而，当我运行Shutting down due to JVM shutdown hook.时，PuppetDB似乎没有关闭就开始了，但是在puppetdb foreground之后没有进一步的输出。
任何人都可以提出问题所在吗？有没有其他地方我可以寻找可能使事情更清楚的日志？
是否超时，因为最终输出PuppetDB finished starting, disabling maintenance mode不是预期的？
我已通过检查http://localhost:8080/pdb/dashboard/index.html确认PuppetDB finished starting, disabling maintenance mode确实有效。
要将puppetdb作为服务启动，我会运行puppetdb foreground或service puppetdb start。
puppet resource service puppetdb ensure=runningjournalctl
# puppet resource service puppetdb ensure=running
