java - 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发挥作用。

当我第一次启动时Tomcat 7 ，它在端口 8080 上运行这是 Tomcat 的默认值。因此可以访问它但键入:http://localhost:8080/或 mydomain.com:8080 .

但我希望从端口 8080 移动到港口80所以我可以输入 mydomain.com并被定向到网页。

我已经禁用了可能在端口 80 上运行的所有额外服务例如 IIS、MSSQL、万维网发布等。

在server.xml文件，我做了以下更改:

<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 时什么也看不见

我在这方面非常陌生 - 浏览了很多在线帖子并遵循了说明，但似乎没有任何效果。我之前已经完成了相同的步骤，而且效果非常好。

我现在必须做什么？请帮忙。

这是我在 netstat 上得到的

Answer 1

一些其他应用正在使用端口 80。使用 netstart 进行本地端口扫描并打印可执行路径(此视频将提供帮助: https://www.youtube.com/watch?feature=player_detailpage&v=V3nWkr7v4-E#t=7 )

通常是 Skype(或其他聊天或点对点文件共享应用程序)。关闭 skype(退出不仅仅是注销，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。

此外，是否有任何防火墙条目阻止 Java 绑定(bind)到此端口？可以从您的防火墙规则中检查 - 如果您使用的是控制面板中的默认 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，那么它会记住这一点。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。

这个程序可能会有所帮助，将它保存到一个名为“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);
    }
}

编译它

javac c:\_your_path\PortCheck.java

并运行它:

java -cp c:\_your_path PortCheck

如果成功绑定(bind)到 80 会告诉你:

Listening on port 80 Bye

同样可以尝试443端口
