Question

我无法在Tomcat服务器上部署Web应用程序。奇怪的是，它在我设置的第二个测试服务器上工作正常。我尽力使两台机器上的环境尽可能相似，并以相同的方式部署应用程序。我现在还不确定如何进行故障排除。

两个服务器都在Tomcat/8.0.37上运行JVM 1.8.0_101-b13，带有MySQL后端（版本14.14 Distrib 5.7.15 for Linux (x86_64) using EditLine wrapper）。两者的操作系统都是Ubuntu 14.04，尽管它们由不同的云提供商托管。我已经通过Manager App的上传功能在两台服务器上部署了.WAR文件。在非工作服务器上，单击“开始”将产生错误 FAIL - 无法启动上下文路径/ mediaServer上的应用程序。在Tomcat的logs/catalina.out文件中，我看到了这个警告：

我在工作服务器上看不到这样的警告。

不确定它是否相关，但工作服务器的Tomcat管理器将操作系统版本显示为3.13.0-30-generic，而非工作服务器显示4.7.0-x86_64-linode72。

其他细节：

我还有另外两个.WAR文件，它们在两台服务器上都已部署并正常运行。
两个服务器上的MySQL数据库名称，内容和凭据都相同。

编辑：

我尝试将有问题的.WAR文件复制到服务器并在webapps目录中手动部署。问题仍然存在，完整的错误日志位于此处：http://sprunge.us/BKLg
我还在本地Windows计算机和远程Windows Server VM上成功部署了.WAR文件。该问题仅发生在这个Ubuntu VM上。

.WAR文件在一个Tomcat服务器上运行，但在另一个
