  debug: msg="This is an install method."

  debug: msg="test uninstall section."

- hosts: localhost
  gather_facts: no
  tasks:
    - name: loading role
      include_role:
        name: test
        tags: deploy

运行

ansible-playbook site.yml

结果是：

PLAY [localhost] ***************************************************************************************************************

TASK [test : deploy] ***********************************************************************************************************
ok: [localhost] => {
    "msg": "This is a install method."
}

TASK [test : uninstall] ********************************************************************************************************
ok: [localhost] => {
    "msg": "test uninstall section."
}

PLAY RECAP *********************************************************************************************************************
localhost                  : ok=2    changed=0    unreachable=0    failed=0

我觉得写的没错的话，应该是仅仅运行deploy那个任务的，为啥所有的任务都运行了？
