我需要在两个远程节点之间复制文件：
请注意，我运行所有 Ansible 任务的控制节点不是上述节点。
我尝试过以下方法：
在 Ansible 的 shell 模块中使用
scp- hosts: machine2
user: user2
tasks:
- name: Copy file from machine1 to machine2
shell: scp user1@machine1:/path-of-file/file1 /home/user2/file1
这种方法会一直持续下去，永远不会结束。
使用
fetchcopy- hosts: machine1
user: user1
tasks:
- name: copy file from machine1 to local
fetch:
src: /path-of-file/file1
dest: /path-of-file/file1
- hosts: machine2
user: user2
tasks:
- name: copy file from local to machine2
copy:
src: /path-of-file/file1
dest: /path-of-file/file1
这种方法会引发如下错误：
访问文件 /Users//.ansible/cp/ansible-ssh-machine2-22- 时出错，错误为：[Errno 102] 套接字上不支持操作：u'/Users//.ansible/cp/ansible- ssh-machine2-22-'
我怎样才能实现这个目标？
正如 @ant31 已经指出的那样，您可以使用
synchronizeinventory_hostdelegate_to您可以将任务放置在
ServerAServerBmodesynchronize将任务放在
ServerB- hosts: ServerB
tasks:
- name: Transfer file from ServerA to ServerB
synchronize:
src: /path/on/server_a
dest: /path/on/server_b
delegate_to: ServerA
这使用默认的
mode: pushServerAServerB这可能看起来很奇怪，因为任务已放在
ServerBhosts: ServerBServerAServerAServerBServerB将任务放在
ServerA- 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
这使用
mode: pullServerB要复制远程到远程文件，您可以使用带有 synchronize
关键字的
delegate_to: source-server 模块：
- hosts: serverB
tasks:
- name: Copy Remote-To-Remote (from serverA to serverB)
synchronize: src=/copy/from_serverA dest=/copy/to_serverB
delegate_to: serverA
此剧本可以从您的
machineC如果您需要通过ansible在两个远程节点之间同步文件，您可以使用这个：
- name: synchronize between nodes
environment:
RSYNC_PASSWORD: "{{ input_user_password_if_needed }}"
synchronize:
src: rsync://user@remote_server:/module/
dest: /destination/directory/
// if needed
rsync_opts:
- "--include=what_needed"
- "--exclude=**/**"
mode: pull
delegate_to: "{{ inventory_hostname }}"
打开
remote_serverpid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsync.log
port = port
[module]
path = /path/to/needed/directory/
uid = nobody
gid = nobody
read only = yes
list = yes
auth users = user
secrets file = /path/to/secret/file
我能够使用 local_action to scp 将文件从机器 A 复制到机器 C，然后将文件复制到机器 B 来解决此问题。
如果您想进行 rsync 并使用自定义用户和自定义 ssh 密钥，则需要将此密钥写入 rsync 选项中。

- name: rsync
hosts: serverA,serverB,serverC,serverD,serverE,serverF
gather_facts: no
vars:
ansible_user: oracle
ansible_ssh_private_key_file: ./mykey
src_file: "/path/to/file.txt"
tasks:
- name: Copy Remote-To-Remote from serverA to server{B..F}
synchronize:
src: "{{ src_file }}"
dest: "{{ src_file }}"
rsync_opts:
- "-e ssh -i /remote/path/to/mykey"
delegate_to: serverA
您也可以将
deletgatescp- name: Copy file to another server
become: true
shell: "scp -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null admin@{{ inventory_hostname }}:/tmp/file.yml /tmp/file.yml"
delegate_to: other.example.com
因为
delegatescp使用复制模块将文件从一台服务器传输到另一台服务器的简单方法
这是剧本
---
- hosts: machine1 {from here file will be transferred to another remote machine}
tasks:
- name: transfer data from machine1 to machine2
copy:
src=/path/of/machine1
dest=/path/of/machine2
delegate_to: machine2 {file/data receiver machine}
2021 年你应该安装包装器：
ansible-galaxy collection install ansible.posix
并使用
- name: Synchronize two directories on one remote host.
ansible.posix.synchronize:
src: /first/absolute/path
dest: /second/absolute/path
delegate_to: "{{ inventory_hostname }}"

已检查：
ansible --version
ansible 2.10.5
config file = /etc/ansible/ansible.cfg
configured module search path = ['/home/daniel/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python3.9/site-packages/ansible
executable location = /sbin/ansible
python version = 3.9.1 (default, Dec 13 2020, 11:55:53) [GCC 10.2.0]
将系统机密从机器 1 传输到机器 2 时，您可能无法在它们之间直接访问，因此涉及
delegate_to~/.ssh/authorized_keys-name "Copy /etc/secrets directory from machine1 and machine2"
delegate_to: localhost
shell: |
ssh machine1 sudo tar -C / -cpf - etc/secrets | ssh machine2 sudo tar -C / -xpf -
例如，要使用 MUNGE 守护进程进行身份验证来设置 ad hoc 计算集群，您可以使用以下命令将凭证从头节点复制到工作节点。
setup_worker.yml- name: "Install worker packages"
apt:
name: "{{ packages }}"
vars:
packages:
- munge
# ...and other worker packages...
become: true
- name: "Copy MUNGE credentials from head to {{ host }}"
delegate_to: localhost
shell:
ssh head.domain.name sudo tar -C / -cpf - etc/munge | ssh {{ ansible_facts["nodename"] }} sudo tar -C / -xpf -
become: false
when: ansible_facts["nodename"] != "head.domain.name"
- name: "Restart MUNGE"
shell: |
systemctl restart munge
become: true
运行方式为
ansible-playbook -e host=machine1 setup_worker.ymlbecome: truehostansible_facts["nodename"]when
