1. Build project: Hello

$micro New –gopath=false Hello

Mod download protoc zip packages (protoc-$VERSION-$PLATFORM.zip) and install: visit https://github.com/protocolbuffers/protobuf/releases download protobuf for micro: go get -u github.com/golang/protobuf/proto go get -u github.com/golang/protobuf/protoc-gen-go go get github.com/micro/micro/v2/cmd/protoc-gen-micro compile the proto file hello.proto: cd hello make protoCopy the code

  1. Generate a Protobuf file

protoc --proto_path=proto --go_out=proto --micro_out=proto proto/hello.proto

  1. Start the service

$micro server $go run main.go // Start hello
