Question

我试图将fabcar网络扩展到在同一系统上运行的2个对等节点。我遇到了一些错误。

我对docker compose文件进行了以下更改。

  peer1.org1.example.com:
  container_name: peer1.org1.example.com
  image: hyperledger/fabric-peer
  environment:
    - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock

    - CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/peer/
    - CORE_PEER_ADDRESS=peer1.org1.example.com:7051

    - 8053:7053
  volumes:
      - /var/run/:/host/var/run/
      - ./crypto-config/peerOrganizations/org1.example.com/peers/peer1.org1.example.com/msp:/etc/hyperledger/msp/peer

      - ./config:/etc/hyperledger/configtx
  depends_on:
    - orderer.example.com
    - couchdb1
  networks:
    - basic

couchdb1:
container_name: couchdb1
image: hyperledger/fabric-couchdb
# Populate the COUCHDB_USER and COUCHDB_PASSWORD to set an admin user and password
# for CouchDB.  This will prevent CouchDB from operating in an "Admin Party" mode.
environment:
  - COUCHDB_USER=
  - COUCHDB_PASSWORD=
ports:
  - 6984:5984
networks:
  - basic

在start.sh文件中，我添加了一行代码以将对等1加入通道。

当执行./startFabric.sh节点时，出现以下错误：

来自守护程序的错误响应，容器未运行。

日志如下：

Digitals-MacBook-Air-3:fabcar digital3$ docker logs b602e1898831  
2018-06-28 08:12:18.923 UTC [main] main -> ERRO 001 **Cannot run peer because error when setting up MSP of type bccsp from directory /etc/hyperledger/msp/peer/: could not load a valid signer certificate from directory /etc/hyperledger/msp/peer/signcerts: stat /etc/hyperledger/msp/peer/signcerts: no such file or directory**

我所做的更改是：

在crypto-config中：将模板计数更改为2。
在docker-compose中，为peer1添加了另一项服务，数据库为couchdb1。无需更改CLI。
在start.sh文件中，我写了一行代码将对等点1添加到通道。

在fabcar目录中运行./startFabric.sh节点时，出现上述错误。

我正在基本网络而不是第一个网络中进行编辑。

我刚刚检查了我的证书目录：如下图

CRYPTOCONFIG-PeerOrganisations-Peers-peer0，peer1

Peer0拥有所有证书

Peer1仅具有msp文件夹，而没有tls文件夹。 msp文件夹仅包含admincerts和密钥库

更新：

我设法为两个对等方生成了证书，并从fabcar目录成功运行了./startFabric.sh节点命令。但是，当我执行enrollAdmin命令时遇到了一个问题。

错误：呼叫注册端点失败，并显示错误[错误：连接ECONNREFUSED 10.228.27.101:7054] 在ClientRequest。（/用户/digital3/fabric-samples/fabcar/node_modules/fabric-ca-client/lib/FabricCAClientImpl.js:883:12）在emitOne上（events.js：116：13）在ClientRequest.emit（events.js：211：7）在Socket.socketErrorListener（_http_client.js：387：9）在emitOne上（events.js：116：13）在Socket.emit（events.js：211：7）在emitErrorNT上（internal / streams / destroy.js：64：8）在_combinedTickCallback（内部/进程/next_tick.js:138:11）在process._tickCallback（内部/进程/next_tick.js:180:9）无法注册管理员：错误：无法注册管理员

您能帮我吗

Answer 1

如果要添加其他对等节点，则还需要生成相关的加密材料。

在基本网络目录中crypto-config.yaml文件的第63行上，将Count的值设置为'2'，例如：

# "Template"
# ---------------------------------------------------------------------------
# Allows for the definition of 1 or more hosts that are created sequentially
# from a template. By default, this looks like "peer%d" from 0 to Count-1.
# You may override the number of nodes (Count), the starting index (Start)
# or the template used to construct the name (Hostname).
#
# Note: Template and Specs are not mutually exclusive.  You may define both
# sections and the aggregate nodes will be created for you.  Take care with
# name collisions
# ---------------------------------------------------------------------------
Template:
  Count: 2
  # Start: 5
  # Hostname: {{.Prefix}}{{.Index}} # default

这将使cryptogen步骤为组织的两个对等节点生成密钥材料：Org1。

将对等方添加到Fabcar网络-Hyperledger Fabric
