ansible-playbook剧本文件的编写

ansible是新出现的自动化运维工具，基于Python开发，集合了众多运维工具（puppet、cfengine、chef、func、fabric）的优点，实现了批量系统配置、批量程序部署、批量运行命令等功能。Ansible架构相对比较简单，仅需通过SSH连接客户机执行任务即可，ansible是基于模块工作的，本身没有批量部署的能力。真正具有批量部署的是ansible所运行的模块，ansible只是提供一种框架。

playbook实际是把多个不同的任务集合到一个ansible可执行yaml文件中，playbook有严格的缩进规范，实战示例：

 1 ---
 2 - name: deploy logs_monitor

29       cron:

37          - {job: "/root/get_gluster_data.py", minute: "1" }
38          - {job: "/ap/sh/log/6.sh", minute: "5" }
