# gRPC in 3 minutes (C++)

|
## Installation
|
|
|
|
|
|
|
|
To install gRPC on your system, follow the instructions to build from source
|
|
|
|
[here](../../BUILDING.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](..).
|
|
|
|
|
|
|
|
### 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.
