在不同的机器上运行Corda节点 [英] Running corda nodes in different machines

问题描述

我在Corda中遇到从甲方到乙方执行欠条的问题.下面是配置详细信息:

I have the problem in Corda regarding performing IOU from Party A to Party B. Below is configuration detail:

• 3 node.conf [甲方，乙方和公证人].
• 在AWS中托管应用程序，因此在节点配置文件中而不是"localhost"中，我给出了机器的IP.我为公证人&授予了相同的IP甲方，乙方则不同.

网络引导成功，并将新创建的节点文件夹分别移至EC2实例并启动了运行节点.但是，当执行从甲方到乙方的借条时，它不起作用.请提出解决问题的方法.

Network Bootstrapping was successful and moved the newly created node folders respective EC2 instances and started run nodes. But when performed the IOU from Party A to Party B it's not working. Please suggest how to resolve the issue.

我在节点日志中看到以下错误:

I see the following error in the node logs:

E 11:34:47+0000 [main] internal.Node.run - Exception during node startup {}
java.net.BindException: Cannot assign requested address: bind
    at sun.nio.ch.Net.bind0(Native Method) ~[?:1.8.0_161]
    at sun.nio.ch.Net.bind(Unknown Source) ~[?:1.8.0_161]
    at sun.nio.ch.Net.bind(Unknown Source) ~[?:1.8.0_161]
    at sun.nio.ch.ServerSocketChannelImpl.bind(Unknown Source) ~[?:1.8.0_161]
    at io.netty.channe

推荐答案

在Corda V3.1中使用 rpcSettings 时，地址和adminAddress必须使用0.0.0.0.

When using rpcSettings in Corda V3.1 the address and adminAddress need to be using 0.0.0.0.

rpcSettings {
    address="0.0.0.0:10003"
    adminAddress="0.0.0.0:10103"
}

这些端点没有在外部发布，因此本地ip仅是Corda的绑定.

These endpoints are not advertised externally so the local ip is solely a binding for Corda.

使用公共ip或DNS时，这将解决以下有关启动cordapp的异常:

This should solve the following exception on starting your cordapp when using public ip or DNS:

E 21:28:56 + 0000 [main] internal.Node.run-节点期间异常启动{} io.netty.channel.unix.Errors $ NativeIoException:bind(..)失败:无法分配请求的地址

E 21:28:56+0000 [main] internal.Node.run - Exception during node startup {} io.netty.channel.unix.Errors$NativeIoException: bind(..) failed: Cannot assign requested address
