Ansible Inventory

参考:https://docs.ansible.com/intro_inventory.html

由于实习要求我学习Ansible,故而开始看,今天遇到的问题是hosts的分组

我一直都是比较奇葩的,所以就把服务器分组就折腾的各种“优雅”

遇到的问题是未对官方文档详细查看,仅仅看了中文文档。

这里是一份 /etc/ansible/hosts 的样本

mail.example.com

[webservers]
foo.example.com
bar.example.com

[dbservers]
one.example.com
two.example.com
three.example.com

对于我来说,想做到的就是像盗梦空间里那样的各种嵌套,由于不熟练,以为分组仅仅是多加一个中括号而已,故而出现了连接问题

我是这样干的,/etc/ansible/hosts

[AAA]

[CCC]
AAA
BBB


$ ansible CCC -m ping
CCC | FAILED => SSH encountered an unknown error during the connection. We recommend you re-run the command using -vvvv, which will enable SSH debugging output to help diagnose the issue

这里就出问题了,原因就是分组他有特殊的规则,必须后面加上:children,想想也对,符合逻辑,不然会出不知道的bug

奇葩的我当然还没结束

[CCC:children]
AAA
BBB

[DDD]
IP3

[EEE:children]
CCC
DDD

当然测试EEE的时候会成功!这就初步达到了我想要的效果了

后面当然还有:var参数,后面再学习
