我有一个完整的ubuntu安装（14），并尝试运行Tomcat7。我已经通过终端安装了它，运行“ sudo service tomcat7 start”命令，该命令应该会启动tomcat，但是当我尝试打开：localhost：8080时，欢迎索引页面未加载，并且出现404错误（找不到文件） 。 8080端口也未打开，这似乎是某种许可问题。



Netstat提供以下内容（请注意，在启动tomcat的情况下，没有监听8080）

解决了：

8080端口未使用，为了确定，我什至尝试将其更改为8089。无论如何，还有别的东西。
我已经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，一切正常。

可以找到分步指南here.

最佳答案

也许您在端口8080上运行了另一个服务，或者内核以某种方式关闭了该端口。尝试配置另一个端口，看看问题是否仍然存在。

编辑：好的，这是可行的部分：打开终端并运行

netstat -t | grep 8080


这应该可以显示当前正在端口8080上监听的所有内容。由于Ubuntu并未立即激活防火墙，这很可能是问题的根源。

另一个编辑：原始问题并未说明您使用的是Android。这是至关重要的信息，因为Android包括SELinux，该SELinux禁止在未经安全层事先同意的情况下打开端口。要允许打开端口，请查看here。
