我想通过SSH连接到运行gridgain实例的远程计算机，并从本地gridgain实例连接到它。可以这样做吗？
如何完成gridgain网络连接？据我所知，节点旋转并侦听47100-47200上的第一个可用端口。但它也开辟了更多的端口。
似乎还不够将远程机器上的47100（远程机器网格交换端口）转发到本地47100.可能通信不只是客户端服务器，而是与远程节点试图连接到我的主节点对称？
是否有关于网络协议的文档？
我尝试了对称转发
端口。
节点能够连接。在本地节点上，我首先收到此警告：
WARN GridTcpCommunicationSpi - Connect timed out (consider increasing 'connTimeout' configuration property) [addr=/10.240.136.167:47100]
WARN GridTcpDiscoverySpi - Timed out waiting for message delivery receipt (most probably, the reason is in long GC pauses on remote node; consider tuning GC and increasing 'ackTimeout' configuration property). Will retry to send message with increased timeout. Current timeout: 5000.
WARN GridDhtPreloader - <gg-utility-sys-cache> Failed to wait for initial partition map exchange. Possible reasons are:
^-- Transactions in deadlock.
^-- Long running transactions (ignore if this is the case).
^-- Unreleased explicit locks.
WARN GridTcpDiscoverySpi - Timed out waiting for message to be read (most probably, the reason is in long GC pauses on remote node. Current timeout: 5000.
当以某种方式尝试连接到10.240.136.167:47100 - 这是远程机器本地IP时，这是一个超时，这显然是不可能的。
但是看起来不错，因为我得到以下内容：
INFO GridDiscoveryManager - Topology snapshot [ver=2, nodes=2, CPUs=6, heap=2.7GB]
执行以下广播测试时：
grid.compute().broadcast(new GridRunnable() {
@Override
public void run() {
System.out.println("hello!");
}
});
我在远程计算机上遇到这个致命错误，无论它是什么：

这些是在GridTcpCommunicationSpi.DFLT_PORTs和GridTcpDiscoverySpi.DFLT_PORTs之间 - 所以这些应该足够了。
关于可能出错的任何想法？

主节点也应该可以从群集中获得。您有两个选择：
