• pip 方式安装无配置文件 config file，可自行根据官方给的例子创建，https://docs.ansible.com/ansible/latest/installation_guide/intro_configuration.html

ansible config: https://docs.ansible.com/ansible/latest/reference_appendices/config.html#ansible-configuration-settings

mkdir /etc/ansible
cd /etc/ansible
curl -O https://raw.githubusercontent.com/ansible/ansible/devel/examples/ansible.cfg

root@DESKTOP-BACQ0O3:/etc/ansible# ansible --version
ansible [core 2.11.2]
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/lib/python3.8/dist-packages/ansible
  ansible collection location = /root/.ansible/collections:/usr/share/ansible/collections
  executable location = /usr/local/bin/ansible
  python version = 3.8.10 (default, Jun  2 2021, 10:49:15) [GCC 9.4.0]
  jinja version = 2.10.1
  libyaml = True

配置 Managed nodes

vim vim /etc/ansible/hosts

[own_machine_group]
111.230.58.139:ssh_port

将 Control node 公钥上传至 Managed nodes

ssh-copy-id -i ~/.ssh/id_rsa.pub root@111.230.58.139 -p ssh_port

判断连通性

root@DESKTOP-BACQ0O3:/etc/ansible# ansible own_machine_group -m ping
111.230.58.139 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}
