127.0.0.1 peer1.bank1.couchdb.com
127.0.0.1 peer1.bank2.couchdb.com

4. 部署 CA 服务

创建 docker-compose 存放目录

shell 复制代码 
mkdir docker

编写 docker-compose-ca.yaml

shell 复制代码 
vim docker/docker-compose-ca.yaml
yaml 复制代码 
# docker/docker-compose-ca.yaml

    container_name: ca.bank2.finance.com
    image: hyperledger/fabric-ca:1.4.9
    command: sh -c 'fabric-ca-server start -d -b admin:adminpw --port 7054'
    environment:
      - FABRIC_CA_SERVER_HOME=/tmp/hyperledger/fabric-ca-server
      - FABRIC_CA_SERVER_TLS_ENABLED=true
      - FABRIC_CA_SERVER_CSR_HOSTS=ca.bank2.finance.com

    networks:
      - bank2
      - finance
    ports:
      - 9054:7054

使用 docker-compose 命令启动 3个 CA 服务器，一个 Orderer 组织的 CA（Orderer CA）和两个银行组织的 CA（Bank1 CA & Bank2 CA）

shell 复制代码 
docker compose -f docker/docker-compose-ca.yaml up -d

启动后查看容器是否启动成功

shell 复制代码 
docker ps -a

查看docker容器内部的启动日志

shell 复制代码 
# 1. docker logs [container id]
# 查看 Orderer CA 日志
docker logs e9ae3e555254
# 查看 Orderer Bank1 CA 日志
docker logs a07c4e9be072
# 查看 Orderer Bank2 CA 日志
docker logs baf413d9215e

# 成功启动容器后，将在 CA 容器的日志中看到以下输出
[INFO] Listening on https://0.0.0.0:7054

# 2. docker compose 查看日志
docker compose -f docker/docker-compose-ca.yaml logs

docker compose -f docker/docker-compose-ca.yaml logs | grep https://0.0.0.0:7054

# ca.bank2.finance.com  | 2024/04/29 09:01:58 [INFO] Listening on https://0.0.0.0:7054
# ca.bank1.finance.com  | 2024/04/29 09:01:58 [INFO] Listening on https://0.0.0.0:7054
# ca.orderer.finance.com  | 2024/04/29 09:01:58 [INFO] Listening on https://0.0.0.0:7054

查看 CA 启动后的目录解构

#   CAPABILITIES
#
#   This section defines the capabilities of fabric network. This is a new
#   concept as of v1.1.0 and should not be utilized in mixed networks with
#   v1.0.x peers and orderers.  Capabilities define features which must be
#   present in a fabric binary for that binary to safely participate in the
#   fabric network.  For instance, if a new MSP type is added, newer binaries
#   might recognize and validate the signatures from this type, while older
#   binaries without this support would be unable to validate those
#   transactions.  This could lead to different versions of the fabric binaries
#   having different world states.  Instead, defining a capability for a channel
#   informs those binaries without this capability that they must cease
#   processing transactions until they have been upgraded.  For v1.0.x if any
#   capabilities are defined (including a map with all capabilities turned off)
#   then the v1.0.x peer will deliberately crash.

    # Batch Timeout: The amount of time to wait before creating a batch.

    # Batch Size: Controls the number of messages batched into a block.
    # The orderer views messages opaquely, but typically, messages may
    # be considered to be Fabric transactions.  The 'batch' is the group
    # of messages in the 'data' field of the block.  Blocks will be a few kb
    # larger than the batch size, when signatures, hashes, and other metadata
    # is applied.
    BatchSize:

        # Max Message Count: The maximum number of messages to permit in a
        # batch.  No block will contain more than this number of messages.
        MaxMessageCount: 500

        # Absolute Max Bytes: The absolute maximum number of bytes allowed for
        # the serialized messages in a batch. The maximum block size is this value
        # plus the size of the associated metadata (usually a few KB depending
        # upon the size of the signing identities). Any transaction larger than
        # this value will be rejected by ordering.
        # It is recommended not to exceed 49 MB, given the default grpc max message size of 100 MB
        # configured on orderer and peer nodes (and allowing for message expansion during communication).
        AbsoluteMaxBytes: 10 MB

        # Preferred Max Bytes: The preferred maximum number of bytes allowed
        # for the serialized messages in a batch. Roughly, this field may be considered
        # the best effort maximum size of a batch. A batch will fill with messages
        # until this size is reached (or the max message count, or batch timeout is
        # exceeded).  If adding a new message to the batch would cause the batch to
        # exceed the preferred max bytes, then the current batch is closed and written
        # to a block, and a new batch containing the new message is created.  If a
        # message larger than the preferred max bytes is received, then its batch
        # will contain only that message.  Because messages may be larger than
        # preferred max bytes (up to AbsoluteMaxBytes), some batches may exceed

我们知道在 Fabric 中支持两种类型的状态数据库。

  • LevelDB 是嵌入对等节点的默认状态数据库。LevelDB 将链码数据存储为简单的键值对，仅支持键、键范围和复合键查询。
  • CouchDB 是一个可选的备用状态数据库，它允许您将分类帐上的数据建模为 JSON，并针对数据值而不是键发出丰富的查询。

我们在这里不使用Peer节点嵌入的 LevelDB，而是使用 CouchDB 作为数据库。
