java - 访问 Tomcat Web 管理器时连接超时

Question

我使用在线教程作为指导，从 Windows 计算机在亚马逊 ubuntu 服务器上安装了 tomcat8。

它从命令行启动，一条消息表明它确实在运行，但是当我尝试访问 web 应用程序时，我发现连接超时。

我浏览了很多可能的在线解决方案，所以我编辑了我的 tomcat-users.xml、我的 server.xml，但是当我输入 http://server_ip:8080 时我没有加载应用程序

当我尝试 localhost:8080 时，访问被拒绝。

请问我如何验证错误？

哦，我还添加了tomcat用户、组和导出的catalina路径。

我是 ubuntu 的新手，你们能帮帮我吗？奥布里加达

这是我从 catalina.out 得到的

问题是，我不再使用这些端口，我在 server.xml 文件中将它们更改为端口 80。

Answer 1

真正对我有用的是在 aws 上打开 8080 端口。就这么简单哈哈:)
