所以我正在制作一个可以编译为二进制文件的负载均衡器。这将在多个服务器上进行扩展。
要更新，程序本身将每 5 分钟检查一次 GitHub 存储库是否有新版本，如果有新版本，它会下载并覆盖旧版本，然后运行命令systemctl restart lb。
现在我的问题是，这是一种不好的做法吗？这样做有什么缺点吗？除此之外还有更好的更新做法吗？

顺便说一句，运行 cronjob 并不理想。
我有一个在端口 3001 上运行的 golang 应用程序。
curl http://127.0.0.1:3001给出正确的 HTML 响应。但是当我尝试通过 NginX 进行 proxy_pass 时，我遇到了问题。
下面是我的 NginX 配置。我正在做一个基于路线的位置块 -
upstream my-app {
server 127.0.0.1:3001;
}
server {
listen 80 default_server;
server_name localhost;
underscores_in_headers on;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
error_page 404 /404.html;
client_max_body_size 300M;
location ^~ /theapp {
proxy_redirect off;
proxy_set_header Host $http_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;
proxy_pass http://my-app;
}
}
当我访问http://example.com/theapp/时，它会下载my-app二进制文件，而不是将 http 请求转发到 my-app。
我究竟做错了什么？
