  sudo -E docker compose up -d

2. 使用 Nginx 代理 Nacos 集群

2.1. `./nginx/etc/nginx.conf`

Nginx

user  nginx;
worker_processes  auto;
pid  /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    map $http_upgrade $connection_upgrade {
        default upgrade;
        ''      close;
    }

    upstream nacos-http {
        server nacos1:8848 max_fails=3 fail_timeout=30s;
        server nacos2:8848 max_fails=3 fail_timeout=30s;
        server nacos3:8848 max_fails=3 fail_timeout=30s;
        hash $remote_addr consistent;
    }

    server {
        listen 8848;

        location / {
            proxy_pass http://nacos-http;

            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_set_header X-Forwarded-Proto $scheme;

            # 添加服务节点标识头
            add_header X-Upstream-Node $upstream_addr always;

            # WebSocket 支持
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection $connection_upgrade;
        }
    }
}

stream {
    # log_format basic '$remote_addr [$time_local] '
    #                  '$protocol $status $bytes_sent $bytes_received '
    #                  '$session_time';

    upstream nacos-grpc {
        server nacos1:9848 max_fails=3 fail_timeout=30s;
        server nacos2:9848 max_fails=3 fail_timeout=30s;
        server nacos3:9848 max_fails=3 fail_timeout=30s;
        hash $remote_addr consistent;
    }

    server {
        listen 9848;

        proxy_pass nacos-grpc;
    }
}

Caution：使用 Nginx 代理请求时，需要配置成 TCP 转发，不能配置 http2 转发，否则连接会被 Nginx 断开。

2.2. `.env`

在原 .env 中添加以下配置项：
