Question

我正在尝试将目录从服务器a复制到服务器b。

这是我的文件：

test.yml

- hosts: server-b  
  tasks:
   - name: Copy Remote-To-Remote (from server-a to server-b)
     synchronize: src=/test-dir dest=/test-dir
     delegate_to: server-a

hosts.yml

all:
  hosts:
    server-a:
      ansible_host: 123.123.123.101
      ansible_user: root
    server-b:
      ansible_host: 123.123.123.102
      ansible_user: root

ansible.cfg

[defaults]
inventory = hosts.yml
host_key_checking = false

此处输出：

$ ansible-playbook test.yml
PLAY [server-b] *******************************************************************************************************************************

TASK [Gathering Facts] ****************************************************************************
********************************************
ok: [server-b]

TASK [Copy Remote-To-Remote (from server-a to server-b)] **************************************************************************************

因此，它挂起并且不复制任何内容。

这是详细的日志（带有-vvvv）：

为什么不远程复制？

Answer 1

答案是，ansible模块“正在运行，并且起源于正在运行Ansible的本地主机。”。参见module documentation。要复制远程复制，您必须交换ssh键。您可以将以下标语用作示例：

- hosts: server-a
  tasks:
    # transfer local pub-key to remote authorized_keys
    - name: fetch local ssh key from root user
      shell: cat /root/.ssh/id_rsa.pub
      register: ssh_keys
      changed_when: false
    - name: deploy ssh key to remote server
      authorized_key:
              user: "root"
              key: "{{ item }}"
      delegate_to: "server-b"
      with_items:
              - "{{ ssh_keys.stdout }}"
    # fetch remote host key and add to local known_hosts
    # to omit key accept prompt
    - name: fetch ssh rsa host key from remote server
      shell: cat /etc/ssh/ssh_host_rsa_key.pub
      register: ssh_host_rsa_key
      delegate_to: server-b
      changed_when: false
    - name: create /root/.ssh/ if not existant
      file:
          path: "/root/.ssh/"
          owner: root
          group: root
          mode: 0700
          state: directory
    - name: add hostkey to root known host file
      lineinfile:
          path: "/root/.ssh/known_hosts"
          line: "{{ server-b.inventory_hostname }} {{ ssh_host_rsa_key.stdout }}"
          mode: 0600

无法使用Ansible同步模块复制远程到远程
