從遠程服務器複製到主管主機失敗

Question

我需要將最新的日誌文件從遠程Linux服務器複製到主管主機。這是我到目前爲止所嘗試的。

- hosts: [host] 
    remote_user: root 
    tasks: 
    - name: Copy the file 
    command: bash -c "ls -rt | grep install | tail -n1" 
    register: result 
    args: 
     chdir: /root 
    - name: Copying the file 
    copy: 
     src: "/root/{{ result.stdout }}" 
     dest: /home 

但我收到以下錯誤。

TASK [Gathering Facts] ******************************************************************************************************************************************************************************************** 
ok 

TASK [Copy the file] ********************************************************************************************************************************************************************************************** 
changed: => {"changed": true, "cmd": ["bash", "-c", "ls -rt | grep install | tail -n1"], "delta": "0:00:00.011388", "end": "2017-06-14 07:53:26.475344", "rc": 0, "start": "2017-06-14 07:53:26.463956", "stderr": "", "stdout": "install.20170614-051027.log", "stdout_lines": ["install.20170614-051027.log"], "warnings": []} 

TASK [Copying the file] ******************************************************************************************************************************************************************************************* 
fatal: FAILED! => {"changed": false, "failed": true, "msg": "Unable to find 'install.20170614-051027.log' in expected paths."} 


PLAY RECAP ******************************************************************************************************************************************************************************************************** 
      : ok=2 changed=1 unreachable=0 failed=1 

但是那個文件就在那裏。請幫我解決這個問題。

Answer 1

Ansible將文件從主機複製到遠程主機。改用Ansible提取。 http://docs.ansible.com/ansible/fetch_module.html

Answer 2

這一個工程，我必須使用抓取而不是複製從遠程獲取文件。

- name: Copy the file 
    command: bash -c "ls -rt | grep install | tail -n1" 
    register: result 
    args: 
     chdir: /root 
    - name: Copying the file 
    fetch: 
     src: "/root/{{ result.stdout }}" 
     dest: /home 
     flat: yes
