ansible 配置面密登陆

inventory 文件host配置，小戳，配置的明文密码；关于加密可查看这篇blog

wfq@ubuntu:/etc/ansible$ cat hosts
[asb]
ubuntu132 ansible_ssh_host=192.168.174.132 ansible_ssh_user=wfq ansible_ssh_pass=wfq
ubuntu133 ansible_ssh_host=192.168.174.133 ansible_ssh_user=wfq ansible_ssh_pass=wfq
ubuntu134 ansible_ssh_host=192.168.174.134 ansible_ssh_user=wfq ansible_ssh_pass=wfq

1. 使用adhoc命令方式

ansible asb -m authorized_key -a "user=wfq key='{{ lookup('file','/home/wfq/.ssh/id_rsa.pub') }}'"

若首次配置的话，要先将/etc/ansible/ansible.cfg配置文件的host_key_checking设置为false，避免本机的~/.ssh/known_hosts文件中并有fingerprint key串的校验而导致报错失败；如文章详细说明

2. 使用ansible-playbook

ansible 官方说该模块说明
playbook文件为：/etc/ansible/playbook/config_no_psw.yml

---
- hosts: "asb"
  gather_facts: false
  tasks:
    - name: config no password 
      authorized_key:
        user: wfq
        state: present
        key: "{{ lookup('file', '/home/wfq/.ssh/id_rsa.pub') }}"

执行及结果

wfq@ubuntu:/etc/ansible/playbook$ ansible-playbook -i /etc/ansible/hosts /etc/ansible/playbook/config_no_psw.yml
