批量管理主机的时候, 需要预先定义主机或者组, 这个文件叫 Inventory, 默认位于 /etc/ansible/hosts.
/etc/ansible/hosts 文件的格式如下:
mail.example.com
[web]
web[1:5].example.com
[db]
db[1:3].example.com
[prod:children]
web
db
mail.example.com
[web]
web[1:5].example.com
[db]
db[1:3].example.com
[prod:children]
web
db
- 指定主机 mail.example.com
- 指定主机组 web, db
- 主机组嵌套 prod
未被分组的主机默认在ungrouped组内
选择主机和组
举例主机清单
srv1.example.com
srv2.example.com
s1.lab.example.com
s2.lab.example.com
[web]
jupiter.lab.example.com
saturn.example.com
[db]
db1.example.com
db2.example.com
db3.example.com
#db[1:3].example.com
