Ansible在节点间传输文件

1. 在控制节点(the control machine )与远程节点( the current remote host)之间传输文件

1.1 如果需要传输文件,可以使用copy模块,注意copy模块不能递归目录：

  copy: src=/path/on/control_machine/{{ item }} dest=/path/on/reomte_host remote_src=yes
  with_items:
    - "file_1"
    - "file_2"

1.2 可以使用unarchive模块传输打包好的文件夹,在远程节点上自动解压:

- name: copy your folder from control machine to remote host
  unarchive: src=/path/on/control_machine/{{ item }} dest=/path/on/reomte_host
  with_items:
    - "file_1"
    - "file_2"

1.3 使用synchronize模块,设置mode=pull，即远程节点从控制机器拉取数据:

- name: copy file from control machine to remote host
  synchronize: mode=pull src=/path/on/control_machine/{{ item }} dest=/path/on/reomte_host
  with_items:
    - "file_1"
    - "file_2"

2.当需要在两个远程主机(remote host )上面互相传输数据时候:

2.1 当远程节点为ServerB的时候，将ServerA的文件夹传输到ServerB上：

- hosts: ServerB
  tasks:
    - name: Transfer file from ServerA to ServerB
      synchronize:
        src: /path/on/server_a
        dest: /path/on/server_b
      delegate_to: ServerA

2.2 当远程节点为ServerA的时候，将ServerA的文件夹传输到ServerB上：

- hosts: ServerA
  tasks:
    - name: Transfer file from ServerA to ServerB
      synchronize:
        src: /path/on/server_a
        dest: /path/on/server_b
        mode: pull
      delegate_to: ServerB

2.3 或者使用SCP命令:

- name: Transfer file from ServerB to ServerA
  shell: scp  -r /path/on/server_b node@ServerA:/path/on/server_a
  ignore_errors: True
  delegate_to: ServerB
