#gRPC in 3 minutes (C++)
|
|
|
|
## Installation
|
|
|
|
To install gRPC on your system, follow the instructions to build from source [here](../../INSTALL.md). This also installs the protocol buffer compiler `protoc` (if you don't have it already), and the C++ gRPC plugin for `protoc`.
|
|
|
|
## Hello C++ gRPC!
|
|
|
|
Here's how to build and run the C++ implementation of the [Hello World](../protos/helloworld.proto) example used in [Getting started](..).
|
|
|
|
The example code for this and our other examples lives in the `examples`
|
|
directory. Clone this repository to your local machine by running the
|
|
following command:
|
|
|
|
|
|
```sh
|
|
$ git clone -b $(curl -L http://grpc.io/release) https://github.com/grpc/grpc
|
|
```
|
|
|
|
Change your current directory to examples/cpp/helloworld
|
|
|
|
```sh
|
|
$ cd examples/cpp/helloworld/
|
|
```
|
|
|
|
### Client and server implementations
|
|
|
|
The client implementation is at [greeter_client.cc](helloworld/greeter_client.cc).
|
|
|
|
The server implementation is at [greeter_server.cc](helloworld/greeter_server.cc).
|
|
|
|
### Try it!
|
|
Build client and server:
|
|
```sh
|
|
$ make
|
|
```
|
|
Run the server, which will listen on port 50051:
|
|
```sh
|
|
$ ./greeter_server
|
|
```
|
|
Run the client (in a different terminal):
|
|
```sh
|
|
$ ./greeter_client
|
|
```
|
|
If things go smoothly, you will see the "Greeter received: Hello world" in the client side output.
