ansible批量推送ssh私钥

1 ansible主机生成ssh密钥对

ssh-keygen  然后全部回车即可

2 指定推送ssh公钥的主机

vi /etc/ansible/hosts

[push]
主机IP1  ansible_ssh_user="用户"  ansible_ssh_pass="密码" ansible_ssh_port=22
主机IP2  ansible_ssh_user="用户"  ansible_ssh_pass="密码" ansible_ssh_port=22

3 编写推送公钥的yaml剧本

vi /etc/ansible/ssh_push.yaml
---
- hosts: push
  user: root
  tasks:
   - name: ssh-copy
     authorized_key: user=root key="{{ lookup('file', '/root/.ssh/id_rsa.pub') }}"

4 执行剧本推送公钥

ansible-playbook /etc/ansible/ssh_push.yaml
