如何让 Tomcat 7 在 Windows Server 2008 的 80 端口上运行？

Question

我花了两天时间试图让它工作。

当我第一次启动 Tomcat 7 时，它在端口 8080 上运行，这是 Tomcat 的默认设置。因此可以访问它，但输入：http://localhost:8080/ 或 mydomain.com:8080。

但我希望从端口8080 移动到端口80，这样我就可以输入mydomain.com 并被定向到网页。

我已禁用所有可能在端口 80 上运行的额外服务，例如 IIS、MSSQL、万维网发布等。

在server.xml 文件中，我进行了以下更改：

<Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />

然后当我启动服务器时，我在日志中得到了这个（尽管服务器启动了）：

当我访问 url mydomain.com 时什么都看不到

我对此非常陌生 - 已经浏览了很多在线帖子并按照说明进行操作，但似乎没有任何效果。我之前做过同样的步骤，效果很好。

我现在必须做什么？请帮忙。

这就是我在netstat 上得到的结果

Answer 1

其他一些应用程序正在使用端口 80。执行本地端口扫描并使用 netstart 打印可执行路径（此视频将有所帮助： https://www.youtube.com/watch?feature=player_detailpage&v=V3nWkr7v4-E#t=7)

通常是它的 Skype（或其他聊天或点对点文件共享应用程序）。关闭Skype（退出不仅仅是退出，进程应该退出）然后启动tomcat。然后可以重新启动Skype，它会在其他一些端口上正常工作。

还有任何防火墙条目阻止 Java 绑定到此端口？可以从您的防火墙规则中检查 - 如果您使用控制面板中的默认 Windows 防火墙。 https://www.youtube.com/results?search_query=widows+firewall+java+allow 这些结果或常规搜索引擎中的相同术语将告诉您允许 Java 的步骤。通常 Windows 会在您第一次运行应用程序时询问。所以如果你说不，它就会记住这一点。还需要具有管理员角色（登录/或提示用户）才能进行这些更改。对于某些问题也有助于打开管理控制台。右键单击cmd.exe并选择以管理员身份运行，对安全提示说是。

此程序可能会有所帮助，请将其保存到名为“PortCheck.java”的文件中

    class PortCheck{
    public static void main(String []args) throws Exception{
        String port = "80";
        if(args.length > 0)port = args[0];
        final int p = Integer.parseInt(port);
        Thread t = new Thread(){
            public void run(){

                try{
                    java.net.ServerSocket s = new java.net.ServerSocket(p);
                    System.out.println("\nListening on port " + p);
                    s.accept();
                }catch(Exception e){
                    System.out.println("Err " + e);
                }
            }
        };
        t.start();
        Thread.sleep(2000);
        System.out.println("Bye ");
        System.exit(0);
    }
}

编译

javac c:\_your_path\PortCheck.java

并运行它：

java -cp c:\_your_path 端口检查

如果成功绑定到80会告诉你：

监听 80 端口 再见

443端口也可以试试
