您能否检查一下我哪里出错了以及我必须在哪些文件中进行更改。我浏览了 raft 的文档，但我不能很好地理解它，也没有我可以通过的好的资源或教程。如果您知道任何好的来源或示例，请提供帮助。我看到超级账本结构社区不如比特币或以太坊这样的区块链强大。我在上面构建应用程序时遇到了很多麻烦。我会请求你帮助我，从我能学到最好的地方。

解决方案

您可以阅读文档以获取更多详细信息和解释，而关键概念是：

  1. 为了使用 Raft，您需要配置您的排序服务以使用 TLS。

  2. 将订购者类型更改为

    OrdererType: etcdraft

  3. 您需要通过添加到配置以下部分来设置您的中心集（Raft 副本）：

    Consenters:

    - Host: raft0.example.com
      Port: 7050
      ClientTLSCert: path/to/ClientTLSCert0
      ServerTLSCert: path/to/ServerTLSCert0
    - Host: raft1.example.com
      Port: 7050
      ClientTLSCert: path/to/ClientTLSCert1
      ServerTLSCert: path/to/ServerTLSCert1
    - Host: raft2.example.com
      Port: 7050
      ClientTLSCert: path/to/ClientTLSCert2
      ServerTLSCert: path/to/ServerTLSCert2

您在其中提供配置以设置您的集群，包括您的中心的 TLS 证书。

例如 Raft 的配置文件可能如下所示，SampleDevModeEtcdRaft配置文件：

SampleDevModeEtcdRaft:
  <<: *ChannelDefaults
Capabilities:
  <<: *ChannelCapabilities
  Orderer:
    <<: *OrdererDefaults
    OrdererType: etcdraft
    EtcdRaft:
    Consenters:
        - Host: raft0.example.com
          Port: 7050
          ClientTLSCert: path/to/ClientTLSCert0
          ServerTLSCert: path/to/ServerTLSCert0
        - Host: raft1.example.com
          Port: 7050
          ClientTLSCert: path/to/ClientTLSCert1
          ServerTLSCert: path/to/ServerTLSCert1
        - Host: raft2.example.com
          Port: 7050
          ClientTLSCert: path/to/ClientTLSCert2
          ServerTLSCert: path/to/ServerTLSCert2        
  Organizations:
      - *OrdererOrg
    Capabilities:
      <<: *OrdererCapabilities
  Application:
    <<: *ApplicationDefaults
    Organizations:
    - <<: *OrdererOrg
  Consortiums:
    SampleConsortium:
      Organizations:
      - *Org1
      - *Org2
