ansible的error处理机制
ignore_errors忽略错误
- 默认情况下，ansible在遇到错误时会立刻停止playbook，后续所有的任务都不会再执行
---
- name: error处理演示剧本
hosts: all
tasks:
- name: 开启一个不存在的服务
service:
name: noname
state: started
- name: 创建一个文件
file:
path: /tmp/service.txt
state: touch
- 使用
ignore_errors可以忽略错误，继续后续的任务
单任务忽略错误

- name: 单任务error处理演示剧本
hosts: all
tasks:
- name: 开启一个不存在的服务
service:
name: noname
state: started
ignore_errors: yes
- name: 创建一个文件
file:
path: /tmp/service.txt

PLAY RECAP *********************************************************************
c8 : ok=3 changed=1 unreachable=0 failed=0 skipped=0 rescued=0 ignored=1

全局忽略错误
单任务忽略错误，只能忽略一个任务的错误，全局忽略错误，不论哪一步出现错误都会忽略错误并继续执行脚本。
