我有一个干净的Ubuntu安装（14），并尝试运行Tomcat7。 我已经通过terminal安装它，运行“sudo服务tomcat7启动”命令应该启动tomcat，但是当我尝试打开：localhost：8080，欢迎索引页面不加载，我得到一个404错误（找不到文件） 。 8080端口也没有打开，这似乎是某种权限问题。
请帮我一下 谢谢！
更新：
8080端口没有被使用，我甚至试图把它改为8089。 还有其他的东西。 我通过命令行删除了所有tomcat7，并手动重新安装。 从Apache网站安装最新版本后，一切都很好。

Netstat给出了以下内容（注意tomcat启动时没有监听8080）

来自PID的Windows进程
在相同的过程中枚举打开的端口
如何更改/查看Windows机器上的临时端口范围？
$ _SERVER 没有提供价值
也许你有另一个服务在端口8080运行，或者你的内核以某种方式关闭了端口。 尝试配置另一个端口，看看问题是否存在。
编辑：好的，这里是可操作的部分：打开终端并运行
netstat -t | grep 8080
这应该会告诉你任何正在侦听端口8080上的东西。由于Ubuntu没有启动防火墙，这很可能是问题的根源。
另一个编辑：原来的问题并没有说明你在Android上。 这是一个重要的信息，因为Android包含了SELinux，它禁止在未经安全层同意的情况下打开一个端口。 要打开这个港口，看看这里 。
在这里你只需要从tomcat管理器中改变端口号，因为有些应用程序可能已经使用了8080的端口号。
使用以下方法…
