[MacOS]Ansible-HelloWorld

1. 安装

pip install ansible

2. 手动创建ansible.cfg

sudo mkdir /etc/ansible/ansible.cfg

3. 查看ansible配置信息

ansible --version

4. 创建hosts文件

cd /etc/ansible/
sudo touch hosts
sudo vi hosts

添加主机IP
127.0.0.1

5. ansible 是基于 ssh协议实现的，所以其配置公私钥的方式与 ssh 协议的方式相同，具体操作步骤如下：

生成私钥
ssh-keygen
向主机分发私钥
ssh-copy-id root@127.0.0.1

6. 测试Ping

ansible -u root 127.0.0.1 -m ping

成功
127.0.0.1 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}

失败
127.0.0.1 | UNREACHABLE! => {
    "changed": false,
    "msg": "Failed to connect to the host via ssh: ssh: connect to host 127.0.0.1 port 22: Connection refused",
    "unreachable": true
}
