Spring Boot 未在 Digital Ocean 上启动

Question

我有一个运行 Ubuntu 并安装了 Java JDK 1.8 的 Droplet。我已经转移了我的弹簧靴脂肪罐。我可以在我的本地机器上执行它没有问题。在 Digital Ocean 上，它无限期地挂起，如下所示。我刚刚将内存从 512MB 升级到 1GB，同样的问题。

Fateddy 的建议没有奏效，但它发现了正确的问题；低熵。使用haveged的https://www.digitalocean.com/community/tutorials/how-to-setup-additional-entropy-for-cloud-servers-using-haveged完美运行。
