How to deploy a web app without stop and restart

I built the project to binary file and deployed it to server before. and start it with nohup. But if I updated my code and rebuild my program. I must to kill the process first, then updated the file and start again.

My problem is:

  1. The app must be down with at least few seconds.
  2. I must update file manually (login the server, kill process, replace file, and then start it)

Is there anyway to hot update the program, something like PHP? I just need update my code to server by git (or svn or others way). then the server will rebuild app and graceful restart it.

Usually you run more than one instance of your web application behind a reversed proxy, eg nginx, or any other load balancer. If the few second downtime is an issue for you then you need to have a HA setup anyway. And in such setup you can do a rolling update, where you are replacing instances one by one.
Quick googling will let you find instructions how to do the deployment eg: https://www.digitalocean.com/community/tutorials/how-to-deploy-a-go-web-application-using-nginx-on-ubuntu-18-04
