我有以下剧本：

---
- hosts: ESNodes
  remote_user: ihazan
  tasks:
  - name: Run Monitoring
    action: command  /tmp/monitoring/cpu_mon

/tmp/monitoring/cpu_mon的内容如下：

top -bn1800 -p $(ps -ef | grep elasticsearch | grep -v grep | grep -v sudo | awk '{print $2}') | grep root > /tmp/cpu_stats &

注意 top 是用 & 运行后台

运行该剧本时，Ansible 永远卡在 top 命令上：

-bash-4.1$ ansible-playbook es_playbook_run.yml -l PerfSetup -K -f 10 
sudo password: 

PLAY [ESNodes] **************************************************************** 

GATHERING FACTS *************************************************************** 
ok: [isk-vsrv643]

TASK: [Run Monitoring] ********************************************************

通过远程 SSH 运行它时（这是 ansible 应该做的）它工作正常：

-bash-4.1$ ssh ihazan@isk-vsrv643 'nohup /tmp/monitoring/cpu_mon'
-bash-4.1$

以下是输出的调试版本：

-bash-4.1$ ansible-playbook es_playbook_run.yml -l PerfSetup -K -f 10 -vvvv
sudo password:

使用“一劳永逸”模式，即 async + poll 0 ：

---
- hosts: ESNodes
  remote_user: ihazan
  tasks:
  - name: Run Monitoring
    action: command  /tmp/monitoring/cpu_mon
    async: 45
    poll: 0

祝你好运。
