nginx 接入gRPC

 

nginx 1.13.10新增了对gRPC的支持，本文介绍通过nginx接入grpc服务。

 

一. nginx版本

$ nginx -V
nginx version: nginx/1.15.6
built by clang 10.0.0 (clang-1000.11.45.5)
built with OpenSSL 1.0.2p  14 Aug 2018
TLS SNI support enabled
--with-http_ssl_module --with-http_v2_module

 若源码安装，需指定http2编译选项：--with-http_v2_module

 

二. grpc负载均衡配置

#grpc服务列表
upstream grpcservs {
    server 127.0.0.1:80;
}

server {
    listen       8080 http2;	#配置http2
    server_name  localhost;

    #location配置
    location /helloworld.Greeter {
        grpc_pass grpc://grpcservs;
    }
}

 

三. 测试

设置greeter_client 连接端口为8080。

$ ./greeter_client

Greeter received: Hello world

 

nginx访问日志：

127.0.0.1 - - [05/Feb/2019:11:01:49 +0800] "POST /helloworld.Greeter/SayHello HTTP/2.0" 200 18 "-" "grpc-c++/1.18.0 grpc-c/7.0.0 (osx; chttp2; goose)" "-"

 

可见nginx配置生效，通过http2协议通信。
