Run Golang as www-data

Question

When I run a Node HTTP server app I usually call a custom function

function runAsWWW()
{
 try 
 {
  process.setgid(\'www-data\');
  process.setuid(\'www-data\');         


        

Answer 1

No. You can't reliably setuid or setgid in go, because that doesn't work for multithreaded programs.

You need to start the program as the intended user, either directly, through a supervisor of some sort (e.g. supervisord, runit, monit), or through your init system.
