启用 raft 模式时 TLS 握手失败

Question

我有一个运行ning Hyperledger Fabric 网络，启用了 TLS 和 Kafka 共识。现在，我一直在尝试转移到 Raft，并且我总是在订购者中收到这条消息：TLS handshake failed with error tls: first record does not look like a TLS handshake server=Orderer remoteaddress=ÌP:PORT。正如我所说，TLS 在更改之前运行良好。

现在我将向您展示我所做的与 RAFT 和 TLS 连接相关的工作。首先，我修改 configtx.yaml 文件，正是与订购服务相关的部分。

configtx.yaml

部分

Orderer: &OrdererDefaults
  OrdererType: etcdraft
  Addresses:
  - orderer0.org1:7050
  - orderer0.org2:7050
  - orderer0.org3:7050

可以看出，来自每个组织订购者的 TLS 客户端和服务器证书都是必需的，因此我在每个订购者容器中生成它们并将其上传到我用来共享的 MinIO 服务器。

echo "[INFO] Generating Client TLS Key and Certificate..."
fabric-ca-client enroll -d --enrollment.profile tls -u ${ENROLLMENT_URL} -M /tmp/tls --csr.hosts ${ORDERER_HOST}

echo "[INFO] Uploading Client TLS Certificate to Minio"
python3 /scripts/minio_upload.py --url ${STORAGE_URL} --access-key ${STORAGE_ACCESS_KEY} --secret-key ${STORAGE_SECRET_KEY} --bucket-name ${ORG} --local-path ${ORDERER_GENERAL_TLS_CLIENTCERT_FILE} --remote-path orderers/${ORDERER_NAME}/tls/$(basename ${ORDERER_GENERAL_TLS_CLIENTCERT_FILE})
echo "[INFO] Client TLS Certificate uploaded"

echo "[INFO] Enrolling orderer..."
fabric-ca-client enroll -d --enrollment.profile tls -u ${ENROLLMENT_URL} -M /tmp/tls --csr.hosts ${ORDERER_HOST}

echo "[INFO] Uploading Server TLS Certificate to Minio"
python3 /scripts/minio_upload.py --url ${STORAGE_URL} --access-key ${STORAGE_ACCESS_KEY} --secret-key ${STORAGE_SECRET_KEY} --bucket-name ${ORG} --local-path ${ORDERER_GENERAL_TLS_CERTIFICATE} --remote-path orderers/${ORDERER_NAME}/tls/$(basename ${ORDERER_GENERAL_TLS_CERTIFICATE})
echo "[INFO] Server TLS Certificate uploaded"

每个订购者生成并上传其证书后，我运行一个新容器，我称之为 genesis，我在其中下载 configtx.yaml，所有订购者证书（到路径在 configtx.yaml 中定义）和其他东西来生成创世块、通道 tx 和锚节点更新。之后，在每个排序节点中，我还将所有排序节点的证书（不知道是否需要）下载到相同的路径，当然，还要复制创世块。

在我设置的所有排序器中 true ORDERER_GENERAL_TLS_CLIENTAUTHREQUIRED 和 ORDERER_GENERAL_TLS_ENABLED。例如，这是 orderer0.org1.

的 TLS 配置

env:
- name: ORDERER_GENERAL_TLS_CERTIFICATE
  value: /etc/hyperledger/orderer/tls/server.crt
- name: ORDERER_GENERAL_TLS_CLIENTAUTHREQUIRED
  value: "false"
- name: ORDERER_GENERAL_TLS_CLIENTCERT_FILE  # This is exposed for TLS connections
  value: /shared-storage/tls/orderer0/client.crt
- name: ORDERER_GENERAL_TLS_CLIENTKEY_FILE  # This is exposed for TLS connections
  value: /shared-storage/tls/orderer0/client.key
- name: ORDERER_GENERAL_TLS_CLIENTROOTCAS  # Has to be the same that FABRIC_CA_CLIENT_TLS_CERTFILES
  value: '[/shared-storage/org1/ca-chain.pem]'
- name: ORDERER_GENERAL_TLS_ENABLED
  value: "true"
- name: ORDERER_GENERAL_TLS_PRIVATEKEY
  value: /etc/hyperledger/orderer/tls/server.key
- name: ORDERER_GENERAL_TLS_ROOTCAS  # Has to be the same that FABRIC_CA_CLIENT_TLS_CERTFILES
  value: '[/shared-storage/org1/ca-chain.pem]'

我错过了什么？问题出在哪里？非常感谢。

Answer 1

错误消息 'first record does not look like a TLS handshake' 表明您 'client' 试图打开普通（即非 TLS）连接。确保所有连接都设置为在各种 'clients' 中使用 TLS（即其他订购者、同行、使用 sdk 的客户端应用程序等）。

已编辑

您缺少订购者的这些环境变量：

      - ORDERER_GENERAL_CLUSTER_CLIENTCERTIFICATE=/shared-storage/tls/orderer0/client.crt
      - ORDERER_GENERAL_CLUSTER_CLIENTPRIVATEKEY=/shared-storage/tls/orderer0/client.key
      # I find strange you use org1 CA in your conf, but I trust you...
      - ORDERER_GENERAL_CLUSTER_ROOTCAS=[/shared-storage/org1/ca-chain.pem]
