次のプレイブックがあります。
---
- hosts: ESNodes
remote_user: ihazan
tasks:
- name: Run Monitoring
action: command /tmp/monitoring/cpu_mon
/tmp/monitoring/cpu_mon の内容は次のとおりです。
top -bn1800 -p $(ps -ef | grep elasticsearch | grep -v grep | grep -v sudo | awk '{print $2}') | grep root > /tmp/cpu_stats &
top が & でバックグラウンドで実行されることに注意してください
その Playbook を実行すると、Ansible がトップ コマンドで永遠に動かなくなります。
-bash-4.1$ ansible-playbook es_playbook_run.yml -l PerfSetup -K -f 10
sudo password:
PLAY [ESNodes] ****************************************************************
GATHERING FACTS ***************************************************************
ok: [isk-vsrv643]
TASK: [Run Monitoring] ********************************************************
リモート SSH 経由で実行すると (これは ansible が行うべきことです)、正常に動作します。
-bash-4.1$ ssh ihazan@isk-vsrv643 'nohup /tmp/monitoring/cpu_mon'
-bash-4.1$
以下は、出力のデバッグ バージョンです。
-bash-4.1$ ansible-playbook es_playbook_run.yml -l PerfSetup -K -f 10 -vvvv
