Question

我在本地tomcat 7.50服务器上运行Web应用程序。操作系统是Mac OS Mavericks。如果我使用本地IP地址（例如192.168.2.153:8089），可以从同一房屋中的所有计算机轻松访问Web应用程序。问题是我无法使用运行Tomcat 7.50服务器的机器的公共IP访问Web应用程序。

这是tomcat服务器的server.xml文件：

Answer 1

您需要通过您的路线（托管服务器的地方）设置称为端口转发的内容：点击此处：http://www.wikihow.com/Set-Up-Port-Forwarding-on-a-Router

小心，因为您将通过互联网访问您的计算机。

在大多数情况下，您的家庭IP地址也是动态的（不时更改），因此请确保使用正确的IP访问服务器。查看http://www.noip.com/以获取经理IP地址。

Answer 2

您需要分配公共IP（如119.56.1.78），并且需要说服您的ISP将带有该IP的流量路由到您的系统。第一部分是微不足道的......使用 ip addr add 119.56.1.78 dev eth0 将该IP添加到systemm并使用 ip addr del 119.56.1.78 dev eth0 删除它。选择正确的IP和接口（可能不是eth0）

至于第二部分 - 不是那么容易，并且不要尝试第一部分，直到你得到IP分配。你有一个家用路由器 - 或者你的ISP调制解调器内置的路由器？如果是这样，它可以分配该IP。您可以删除路由器并将服务器暴露给WAN - 但是需要考虑安全问题。

您可以将本地路由器配置为将端口9090转发到本地系统（192.168.1.1），并且根本不添加其他IP。但没有更多的信息没有人能猜出如何。

我无法使用公共IP地址访问我运行的Tomcat 7.50
