nacos 2.0 GRPC SLB（nginx）如何配置

作者：admin 2021-04-17 我要评论

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 ...

（在说正事之前，我要推荐一个福利：你还在原价购买阿里云、腾讯云、华为云服务器吗？那太亏啦！来这里，新购、升级、续费都打折，能够为您省60%的钱呢！2核4G企业级云服务器低至69元/年，点击进去看看吧>>>)

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
    }
}
