實戰(zhàn)Caliper測試多機Fabric環(huán)境

成功跑完caliper自帶例子之后，本人嘗試使用caliper來測試自己部署的多機fabric環(huán)境。

被測fabric網(wǎng)絡(luò)拓撲

1orderer、3peer、kafka共識、無ca、native啟動（非docker）。

IP 節(jié)點 域名
10.254.186.164 orderer orderer.example.com
10.254.186.164 peer peer0.org1.example.com
10.254.247.165 peer peer1.org1.example.com
10.254.207.154 peer peer0.org2.example.com
10.254.186.164 kafka 無需

注：配置文件中關(guān)于fabric的msp等文件需要生成好以后復(fù)制到對應(yīng)的地點。

遇到的問題

安裝問題：

  • error: [join-channel.js]: Failed to join peers, TypeError: Cannot read property 'getConnectivityState' of undefined
    問題： grpc的版本錯誤 必須v.1.10.1
  • info: [bench-flow.js]: #######Caliper Test######
    (node:25548) DeprecationWarning: grpc.load: Use the @grpc/proto-loader module with grpc.loadPackageDefinition instead
    問題：nodejs的版本要是8.x（不能太低也不能太高）

執(zhí)行問題

  • error: [Peer.js]: sendProposal - timed out after:120000
    問題：超時時間設(shè)置過短。 src/fabric/e2eUtils.js里調(diào)整超時時間

  • channel已存在要設(shè)置：


    image.png
  • 由于是已經(jīng)啟動好的鏈碼，如果已經(jīng)安裝上chaincode再次測試會報錯，需要調(diào)整代碼。可以看Pr162的解決辦法，在區(qū)塊鏈網(wǎng)絡(luò)配置中chaincodes項加deployed參數(shù)，并且在src/fabric/install-chaincode.js文件以及src/fabric/instantiate-chaincode.js文件中加入相應(yīng)的處理邏輯：
    https://github.com/hyperledger/caliper/pull/162
    具體：在安裝初始化之前chaincodes的deployed為false:
    "chaincodes": [{"id": "simple11", "path": "contract/fabric/simple/go", "language":"golang", "version": "v2", "channel": "mychannel","deployed": false}],

安裝成功后再執(zhí)行的時候 chaincodes的deployed為true

 "chaincodes": [{"id": "simple11", "path": "contract/fabric/simple/go", "language":"golang", "version": "v2", "channel": "mychannel","deployed": true}],
