Tomcat7 在部署应用程序时挂起

Asp*_*lis 10 deployment tomcat

我在 Ubuntu 14.04 上的 Tomcat 7 中有一些非常奇怪的行为。

我创建了一个新的 VPS，安装了 default-jdk 和其他简单的东西。下载并解压 Tomcat 7。检查它是否在 上运行[myIP]:8080，并看到了 Tomcat 的索引页面。

重新启动 VPS 后，我再次启动了 Tomcat，然后... 上没有响应[myIP]:8080。甚至没有错误。当我检查日志时，我看到 Tomcat 只是在第一个 webapp 上处于部署状态。

我的日志：

直到第 74 行，这是一个正常的服务器启动。部署了所有标准的 web 应用程序（第 48-68 行），但之后它就挂了。所以，我停止了服务器并重新启动了我的系统。再次启动tomcat，奇迹开始了。下一个会话在第 89-136 行，您可以看到没有Server startup in xxxx ms.

它只是在部署中挂起，这种情况一直在重复。什么可能导致这种情况？我已经花了几个小时来解决这个问题，我快疯了，一无所获。

一个可能的问题是 Tomcat 等待熵建立。拿几个线程转储jstack看看谁在等什么。

Tomcat 7+ 严重依赖SecureRandom类为其会话 ID 和其他事物提供随机值。根据您的 JRE，如果用于初始化的熵源SecureRandom缺少熵，则可能会导致启动期间的延迟。

如果问题是熵，可以通过设置以下系统属性来配置 JRE 以使用非阻塞熵源： 

-Djava.security.egd=file:/dev/./urandom
