ansible-playbook 基础介绍
playbook是由一个或多个模块组成的，使用多个不同的模块，完成一件事情。playbook通过yaml语法识别描述的状态文件。扩展名是yaml
1.YAML三板斧
- 缩进
- YAML使用一个固定的缩进风格表示层级结构,每个缩进由两个空格组成, 不能使用tabs
- 冒号
- 以冒号结尾的除外，其他所有冒号后面所有必须有空格。
- 短横线
- 表示列表项，使用一个短横杠加一个空格。
- 多个项使用同样的缩进级别作为同一列表。
- 安装httpd服务->playbook
1.安装
2.配置
3.启动
2. ansible playbook 安装apache 示例
