解决方案：
1、暴露 nacos 集群的端口偏移1000
例如：nacos默认端口8848，需要把9848（8848+1000）也暴露出来
2、修改 nginx.conf 的文件
http {
# 负载均衡配置
upstream lb-nocos{
server 127.0.0.1:8845 weight=1;
server 127.0.0.1:8847 weight=1;
server 127.0.0.1:8849 weight=1;
}
# nacos服务配置
server {
listen 8848;
server_name localhost;
location / {
# 反向代理
proxy_pass http://lb-nocos;
}
}
}
# nacos的grpc协议配置
stream {
# 负载均衡配置（TCP长连接配置）
upstream lb-nocos-tcp{
server 127.0.0.1:9845 weight=1;
server 127.0.0.1:9847 weight=1;
server 127.0.0.1:9849 weight=1;
}
server {
listen 9848;
proxy_pass lb-nocos-tcp;
}
}
