篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了启动链码报rpc error: code = Unimplemented desc = unknown service protos.ChaincodeSupport start error(示例代码相关的知识，希望对你有一定的参考价值。
启动链码时报错如下：
[email protected]:/opt/gopath/src/chaincode/chaincode002# CORE_PEER_ADDRESS=peer:7051 CORE_CHAINCODE_ID_NAME=mycc:0 ./chaincode002
2018-05-28 01:15:24.369 UTC [shim] SetupChaincodeLogging -> INFO 001 Chaincode log level not provided; defaulting to: INFO
2018-05-28 01:15:24.369 UTC [shim] SetupChaincodeLogging -> INFO 002 Chaincode (build level: ) starting up ...
2018-05-28 01:15:24.374 UTC [shim] func1 -> ERRO 003 Received error from server, ending chaincode stream: rpc error: code = Unimplemented desc = unknown service protos.ChaincodeSupport
start error
主要原因是版本问题v1.1.0，7051端口应该使用在v1.0.0
所以在v1.1.0正确的启动chaincode命令为：
CORE_PEER_ADDRESS=peer:7052 CORE_CHAINCODE_ID_NAME=mycc:0 ./chaincode002
