 protobuf

Can be used directly brew install protobuf write in, you can go git  https://github.com/protocolbuffers/protobuf/releases download the latest installation package can be downloaded and then compile. The following can be the final installation.

After unpacking the bin folder adding environment variables, adding or inside protoc.exe path environment variable, this is our exe file conversion protobuf tools.

Then we use some golang for protobuf tool, go get the appropriate library

go get -u -v github.com/golang/protobuf/{proto,protoc-gen-go}
go get -u -v github.com/micro/protoc-gen-micro

consul

Direct command to install or use to https://www.consul.io/downloads.html 

brew install consul

　After downloading adding environment variables, start

consul agent -dev

mkdir $ GOPATH / src / google.golang.org 
cd $ GOPATH / src / google.golang.org 

git clone https://github.com/grpc/grpc-go.git grpc 
git clone https://github.com/ google / go-genproto.git genproto

    README.md   # A readme with command used
    handler/    # Example rpc handler
    main.go     # The main Go program
    proto/      # Protobuf directory
    subscriber/ # Example pubsub Subscriber

　　Then run

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

　　Ensure etcd or consul before the final run is open state

go run main.go

　　You can see the complete a project.
