Question

我的剧本中有以下变量：

SELECT tblDropDownItems.TaskID, tblDropDownItems.TaskName
FROM
    (SELECT 0 AS TaskID, 'Installation' AS TaskName, 'B' AS ItemType
     UNION
     SELECT 1 AS TaskID, 'Setup' AS TaskName, 'B' AS ItemType
     UNION
     SELECT 2 AS TaskID, 'Feedback' AS TaskName, 'B' AS ItemType
     UNION
     SELECT 3 AS TaskID, 'Customer' AS TaskName, 'B' AS ItemType
     UNION
     SELECT 4 AS TaskID, 'Production' AS TaskName, 'P' AS ItemType
     UNION
     SELECT 5 AS TaskID, 'Debug' AS TaskName, 'P' AS ItemType
     UNION
     SELECT 6 AS TaskID, 'Review' AS TaskName, 'P' AS ItemType
     UNION
     SELECT 7 AS TaskID, 'Network' AS TaskName, 'P' AS ItemType
     UNION
     . . . your select clause for 'S' ItemType
     UNION
     . . . your select clause for 'O' ItemType) tblDropDownItems
INNER JOIN
     (SELECT ItemType
      FROM TblItem
      WHERE ItemID = [ItemID]) tblItemType
ON tblDropDownItems.ItemType = tblItemType.ItemType

我需要能够通过Ansible剧本步骤在文件中写入以下内容：

frontends:
  - domain01.fr
  - domain02.fr
  - domain03.fr
  - domain04.fr

我想出了以下解决方案，但我对此不满意。

tcp://domain01.fr:11211,tcp://domain02.fr:11211,tcp://domain03.fr:11211,tcp://domain04.fr:11211

我无法在- name: Setting up Apache (2/2) lineinfile: path: /etc/opt/rh/rh-php56/php.ini regexp: '^session.save_path =' line: "session.save_path = 'tcp://{{ frontends | join(':11211,tcp://') }}'"方法内部硬写域，因为它依赖很多，而且在某些情况下我只有2个域而不是4个域。

是否可能会有类似以下的内容：

lineinfile

提前谢谢

是的。这是可能的。下面的 line

regexp: '^session.save_path ='
line: >-
  session.save_path ={% for frontend in frontends %}
  tcp://{{ frontend }}:11211{% if not loop.last %},{% endif %}{% endfor %}

给予

session.save_path = tcp://domain01.fr:11211, tcp://domain02.fr:11211, tcp://domain03.fr:11211, tcp://domain04.fr:11211

在这种情况下，如何在数组周围循环？
