Linux 无法将文件保存到/var/www/html——即使我在www数据组中

我想保留root作为/var/www的所有者

我想让集团www数据访问/var/www和/var/www/*rwx

我相信apache的用户是www数据。我将自己的user:devon添加到该组中，但仍然无法将文件保存到/var/www/html。救命啊

下面是我在下面试图做的非常清楚的事情。我错过了什么

devon@cheap-dell /var $ ls -l

答案是：注销，然后重新登录以使组更改生效。这是巴尔马的回答

更改组后，您需要注销并再次登录，以使更改生效。groups devon将在下次登录时显示您将拥有的组。“组”显示您当前拥有的组。或者，不要注销并重新登录，而是执行一个新的GRP www DATALL，确保您还具有对目录的x权限。w还不够，太棒了。注销/登录。工作！谢谢-现在我不知道该如何接受这个答案。
