ansible run command on remote host in background

Question

I am trying to start filebeat (or for that matter any other process which will run continuously on demand) process on multiple hosts using ansible. I don't want ansible to wait till the process keeps on running. I want ansible to fire and forget and come out and keep remote process running in back ground. I've tried using below options:

    ---     - hosts: filebeat       tasks:       - name: start filebeat option a)  command: filebeat -c filebeat.yml & option b)  command: nohup filebeat -c filebeat.yml & option c)  shell: filebeat -c filebeat.yml &            async: 0 //Tried without as well. If its > 0 then it only waits for that much of time and terminates the filebeat process on remote host and comes out.            poll: 0 

Answer 1

Simplified answer from link I mentioned in the comment:

--- - hosts: centos-target   gather_facts: no   tasks:     - shell: "(cd /; python -mSimpleHTTPServer >/dev/null 2>&1 &)"       async: 10       poll: 0 

Note subshell parentheses.

Update: actually, you should be fine without async, just don't forget to redirect stdout:

- name: start simple http server in background   shell: cd /tmp/www; nohup python -mSimpleHTTPServer </dev/null >/dev/null 2>&1 &
