Question

使用Ansible来托管服务器（172.19.113.104）我要复制文件（ ansibletest 和 MariaDB-client-5.1.67-122.el5.x86_64.rpm >）从远程服务器（172.19.113.87），但是如果文件已经存在，则不应复制。

我尝试如下，但抛出错误：

- hosts: webservers
  vars:
   ip: 172.19.113.87
  tasks:
  - name: this is to pull
    local_action: shell 'ls /opt/ansibletest'
    register: result

  - name: ts2
    synchronize:  src={{ item }} dest=/opt/ mode=pull
    with_items:
    - "/opt/ansibletest"
    - "/opt/MariaDB-client-5.1.67-122.el5.x86_64.rpm"
    when: result.shell.exists == true









[root@rbtstaging ansible]# ansible-playbook fetch.yml

注意：文件存在并获得许可

Answer 1

您可以通过本地“ stat”操作来预先进行抓取（从远程服务器抓取文件-副本会将文件发送到删除服务器），并检查是否存在本地文件。

local_action:
  module: stat
  path: /path/to/local/file
register: local_file
become: no

fetch:
  src: /path/to/remote/file
  dest: /path/to/local/file
  flat: yes
when: local_file.stat.exists == False

Ansible命令从远程服务器提取文件并防止该文件已经存在
