试图将资源管理器与托管在不同机器上的Hyperledger fabric网络连接时出现的问题

Question

我正在为在不同机器上运行的fabric网络设置资源管理器(比如IP 12.34.56.78)，当我试图从资源管理器启动脚本start.sh时，我遇到了这个错误。在单个实例上成功连接(在单个机器上同时连接资源管理器和fabric )，但是当试图在不同的机器上连接时会遇到错误。

这里是我正在更改参数的config.json文件。

Answer 1

您在SDK中设置了发现选项吗？

这里链接到官方HL NodeJS Fabric SDK文档中的发现选项。

https://fabric-sdk-node.github.io/release-1.4/module-fabric-network.Gateway.html#~DiscoveryOptions

Answer 2

您可能需要在fabric网络上添加资源管理器机器的IP地址，还需要将权限文件从fabric网络机器复制到资源管理器机器，类似于sftp协议。

Answer 3

您没有在DISCOVERY_AS_LOCALHOST start.sh文件中将环境变量设置为false。这就是你看到的原因:本地主机。

确保检查explorerconfig.json是否同步进程从不同位置运行

 "sync": {
    "type": "host"
 }
