启动链码报rpc error: code = Unimplemented desc = unknown service protos.ChaincodeSupport start error

参考链接：https://stackoverflow.com/questions/48007519/unimplemented-desc-unknown-service-protos-chaincodesupport

启动链码时报错如下：

root@95a911a49341:/opt/gopath/src/chaincode/chaincode002# CORE_PEER_ADDRESS=peer:7051 CORE_CHAINCODE_ID_NAME=mycc:0 ./chaincode002

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
