nginx 接入 grpc

明文传输

upstream backend {
    #  把下面的服务端地址和端口改成你自己的
    server 127.0.0.1:50052;
    server 127.0.0.1:50051;
}

server{
    listen 80 http2;

    location /hello.Hello {
        grpc_pass grpc://backend;
    }
}

加密传输

upstream backend {
    #  把下面的服务端地址和端口改成你自己的
    server 127.0.0.1:50052;
    server 127.0.0.1:50051;
}

server{
    listen 80 default ssl http2;

    #证书(公钥.发送到客户端的)
    ssl_certificate ssl/server.crt;

    #私钥,
    ssl_certificate_key ssl/server.key;

    location /hello.Hello {
        grpc_pass grpcs://backend;
    }
}
