Hyperledger Fabric 对等通道获取配置问题

Question

我正在尝试将新组织添加到 Fabric 的 v2.2 测试网络。当我执行命令时（在 configUpdate.sh 上；环境变量已正确设置）：

  peer channel fetch config config_block.pb -o orderer.example.com:7050 --ordererTLSHostnameOverride orderer.example.com -c $CHANNEL --tls --cafile "$ORDERER_CA"

我获得：

Error: failed to create deliver client for orderer: orderer client failed to connect to orderer.example.com:7050: failed to create new connection: connection error: desc = "transport: error while dialing: dial tcp: lookup orderer.example.com on 193.231.252.1:53: no such host"

为什么订购者客户端不拨打 localhost:7050（订购者的地址）？编辑：193.231.252.1 是在 /etc/resolv.conf 中配置的名称服务器并且可以访问（通过 ping）Full log is here.

/etc/hosts:

127.0.0.1   localhost
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.17.0.2  e6944b966388

订购者日志：

来自 org1 和 org2 的节点可以连接到排序节点。

有人有什么建议吗？提前致谢，

Answer 1

像这样编辑你的/etc/hosts，添加以下内容：

127.0.0.1 orderer.example.com

#or
#your IP orderer.example.com

这些将告诉您的客户如何找到您的排序服务器

Answer 2

peer channel fetch config config_block.pb -o IPAddress:7050 --ordererTLSHostnameOverride orderer.example.com -c $CHANNEL --tls --cafile "$ORDERER_CA"

确保您的端口是可访问的或开放的端口。
