grpc使用nginx代理配置

参考：https://www.nginx.com/blog/nginx-1-13-10-grpc/

重点是标记红色的部分

http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent"';

    server {
        listen 80 http2;

        access_log logs/access.log main;

        location / {
            # Replace localhost:50051 with the address and port of your gRPC server
            # The 'grpc://' prefix is optional; unencrypted gRPC is the default
            grpc_pass grpc://localhost:50051;
        }
    }
}

比如下面这个：

这里配置用的是openresty，-V查看的时候并没有查看到grpc相关模块，就能支持了，可能是已经有人装了模块了吧，或者默认就能用？

访问：http://xxx.internalxxx.com:50051

生产配置案例：

upstream xxx-internalxx50051 {
server 10.0.0.49:50051  weight=10000 max_fails=3;
 server 10.0.0.193:50051  weight=10000 max_fails=3;
 server 10.0.0.41:50051  weight=10000 max_fails=3;
    keepalive 64;
}

server {
    listen 50051 http2;
    server_name xxx.internalxxx.com;

    location / {
            grpc_pass grpc://xxx-internalxx50051;

            #proxy_pass http://xxx-internalxx50051;
            #proxy_redirect    off;
            #proxy_set_header Host $host;
            #proxy_set_header X-Real-IP $remote_addr;
            #proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            #proxy_http_version 1.1;
    }

    access_log /data/logs/nginx/xxx-internalxx2_access.log main;
    error_log /data/logs/nginx/xxx-internalxx2_error.log;
}
