Can PM2 be used with compiled c programs

Question

Is it possible to use pm2 with custom c programs? If so, how is this accomplished? Does it work well? Is you are already using pm2 for node.js apps would it make sense to use it for a c program as well?

Answer 1

In order to run an precompiled executable file or binary, you need to add "exec_interpreter": "none" and "exec_mode" : "fork_mode" in your JSON file.

{
  "apps" : [{
    "name"       : "binary",
    "script"     : "./binary",
    "exec_interpreter": "none",
    "exec_mode"  : "fork_mode"
  }]
}

Answer 2

From testing it is as simple as specifying the executable file. For example to run a c program compiled to a.out use pm2 start a.out.
