官方提供@yunTaoScripts Ansible 清单文件 🔥🔥

指定清单文件

[root@rhel8-81 task2]# ansible -i hosts.bak xyt -m ping
rhel8-82 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}
rhel8-83 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}

包含主机组

[root@rhel8-81 task2]# ansible -i hosts.bak zz --list-hosts
  hosts (4):
    rhel8-84
    rhel8-85
    rhel8-86
    rhel8-87
[root@rhel8-81 task2]# cat hosts.bak 
[xyt]
rhel8-84
rhel8-85
[abc]
rhel8-86
rhel8-87
[zz:children]
xyt
abc 

变量优先级

• 在 xyt 主机组的 的主机 会应用 group_vars 文件夹下的配置。

[root@rhel8-81 task2]# mkdir group_vars/xyt
[root@rhel8-81 task2]# pwd
/root/ansible/task2
[root@rhel8-81 task2]# ls | grep group_vars/xyt/main.yaml

优先级顺序 role_var > playbook_var > group_vars(如果节点在 主机组中，否则使用 default_vars)> default_vars
