Write your own playbook batch modify the password and the public key push to achieve free dense login!
Due to the need the need to write this thing, put this record down.
The first step: using ssh-keygen -t rsa generate the key pair.
Step two: add ansible hosts, this is my test instead.
Step 3: Define the server sshd_config documents in the root login privileges is turned on.
Example code:

• hosts: test
  sudo: yes
  tasks:
  • name: 修改sshd_config文件
    shell: sed -i 's/PermitRootLogin no/PermitRootLogin yes/g' /etc/ssh/sshd_config
    notify: restart sshd
  • name: change the root password
    shell: echo 'password' | passwd --stdin root
  • name: 分发公钥
    authorized_key:
    user: root
    key: "{{ lookup('file', '/root/.ssh/id_rsa.pub') }}"
    state: present
    exclusive: no
    handlers:
  • name: restart sshd
    shell: service sshd restart
