ansible playbook是一系列ansible命令的集合,利用yaml(Yet Another Markup Language)语言编写。playbook命令根据自上而下的顺序依次执行。
playbook基本语法
vim users.yml
---
- name: create user
hosts: webservers, prod
tasks:
- name: create admin1
user:
name: admin1
state: present
- name: create it group
group:
name: it
state: present
ansible-playbook --syntax-check users.yml
ansible-playbook -C users.yml
ansible-playbook users.yml
# ---:顶格写,作为语法开头。
# - name:顶格写,描述信息,可为空。
# hosts:主机组
# tasks:定义要做的任务,一个任务由一个-开始,如果name前不加-,则user前面必须加-
# user:使用user模块
# state:定义是存在(present)还是不存在(absent)
# -C:测试playbook,不会真的执行。有的时候后面的操作需要依赖前面的操作,所以不一定测试失败,真的执行的时候也会失败
