部署在Tomcat上的应用程序，错误404

Question

我有一个java网络应用程序在AWS server上工作正常。但是，经过一段时间，也许是一些我无法记住的细微变化，我得到404 error。

我尝试重启服务器，重新启动tomcat重新部署应用程序。

没有任何作用，我也设置了公开RWX权限。

Tomcat版本是7，Java也是如此。这一切都来自AMI的{​​{1}}包。

我尝试去的时候得到的结果相同：AWS

有什么想法吗？我可以提供更多信息吗？

/manager/index.jsp

也许解决方案是重新安装Tomcat，但有没有办法从AWS全新安装它？还是一些回滚？

我能够摆脱server.xml中的上述错误，但catalina.out的问题仍然存在。

现在我可以访问404并登录。但是，我的应用仍会显示404.
