在后台运行Golang Web服务器

What is the simplest way to run a go server in the background? I currently have the server running in CMD and would rather not change the actual code.

I'd use a screen. Assuming Ubuntu 18.04:

sudo apt-get install screen

Then

screen

Then

go run main.go

Use Ctrl + A + D to get out of the screen. To return to it:

screen -r
