Tomcat7不会在ubuntu上启动（全新安装），权限被拒绝[关闭]

【问题标题】：Tomcat7 won't start up on ubuntu (clean install), permission denied [closed]Tomcat7不会在ubuntu上启动（全新安装），权限被拒绝[关闭]
【发布时间】：2024-01-15 09:22:01
【问题描述】：

我有一个干净的 ubuntu 安装 (14) 并尝试运行 Tomcat7。我已经通过终端安装了它，运行应该启动 tomcat 的“sudo service tomcat7 start”命令，但是当我尝试打开时：localhost:8080，欢迎索引页面没有加载，我收到 404 错误（找不到文件） . 8080端口也没有打开，好像是权限问题。

Netstat 给出以下信息（注意在启动 tomcat 时没有监听 8080）

android@localhost:~$ netstat -a | more

已解决：

8080端口没有被使用，我什至尝试将其更改为8089以确保。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。

可以在here.找到分步指南

【问题讨论】：

  • 您是否已经尝试过查找 Tomcat 的 startup.sh 并且在使用 shell 脚本启动 Tomcat 时遇到任何错误？
  • 尝试命令“netstat -tuplen”并查看正在使用的端口列表以及进程 ID。查看哪个PID绑定了8080

标签： java ubuntu tomcat7 port


【解决方案1】：

也许您在端口 8080 上运行了另一个服务，或者您的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，可操作的部分来了：打开终端并运行

netstat -t | grep 8080

这应该向您显示当前在端口 8080 上侦听的任何内容。由于 Ubuntu 没有立即激活防火墙，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。这是一条至关重要的信息，因为 Android 包含 SELinux，它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。

【讨论】：

  • 应该是评论
  • @lllogiq, "netstat -t | grep 8080"- 没有结果。之后，我将端口更改为 8077，并重新启动了 tomcat，但我得到了完全相同的错误。我是通过 VNC 连接到系统的，我已经在 Android 系统上部署了 ubuntu。反过来，昨天在清理安装之前，我运行 Apache2 没有问题。
  • @MDeSchaepmeester，你可能是对的。我添加了一个简单的命令来确定这是否确实是问题的根源。现在是答案还是我应该删除它并作为评论重新发布？
  • @lllogiq 让我们拭目以待，看看 OP 怎么说
  • @lllogiq - 有趣的建议。 SELinux 很可能是罪魁祸首。在此处查看有关故障排除的更多详细信息以及可能的修复方法：techrepublic.com/blog/linux-and-open-source/…。
【解决方案2】：

这里你只需要从 tomcat 管理器中更改端口号，因为某些应用程序可能已经在使用你提供的 8080 端口。

使用下面的方法...
