nacos 2.0 GRPC SLB（nginx）如何配置

Question

Nginx配置

upstream nacos-cluster-test{

server 172.22.1.82:8848 weight=1;
server 172.22.1.83:8848 weight=1;
server 172.22.1.84:8848 weight=1;

}
upstream nacos-grpc-9848{

  server 172.22.1.82:9848 weight=1;
  server 172.22.1.83:9848 weight=1;
  server 172.22.1.84:9848 weight=1;

}
upstream nacos-grpc-9849{

  server 172.22.1.82:9849 weight=1;
  server 172.22.1.83:9849 weight=1;
  server 172.22.1.84:9849 weight=1;

}

server {

    listen       8848;
    server_name  localhost;
    location / {
                   #请求转向taishan定义的服务器列表
                   proxy_pass http://nacos-cluster-test;
                   #将请求头转发给后端服务器
                   proxy_set_header Host $host:8848;
                   #后端的Web服务器可以通过X-Forwarded-For获取用户真实IP
                   proxy_set_header X-Forward-For $remote_addr;
                   root  /nacos/;
                   index index.php index.html index.htm;               
             }
}

# grpc 代理配置

server {

    listen 9848 http2; # grpc方式对外暴露端口
    # access_log logs/access.log main;
    location / {
        grpc_pass grpc://nacos-grpc-9848; # 此处配置grpc服务的ip和端口
    }
}
server {
    listen 9849 http2; # grpc方式对外暴露端口
    # access_log logs/access.log main;
    location / {
        grpc_pass grpc://nacos-grpc-9849; # 此处配置grpc服务的ip和端口
    }
}

## 求nginx正确配置？
在线等，谢谢！！！！

Answer 1

官方文档仔细阅读 nginx的配置需要把Grpc 配置成tcp的。
