我最近安装了Codiad IDE，并按照自述文件中的说明操作，我还指定了www-data组来运行安装了codiad的/ var / www / web文件夹，并且已经为所有人提供了正确的文件权限文件夹但我在尝试保存文件时出现此错误
Nov 1 19:27:57 MultiCrew apache2: PHP Warning: fopen(/var/www/test/index.html): failed to open stream: Permission denied in /var/www/web/components/filemanager/class.filemanager.php on line 453
Nov 1 19:27:57 MultiCrew apache2: PHP Stack trace:
Nov 1 19:27:57 MultiCrew apache2: PHP 1. {main}() /var/www/web/components/filemanager/controller.php:0
Nov 1 19:27:57 MultiCrew apache2: PHP 2. Filemanager->modify() /var/www/web/components/filemanager/controller.php:82
Nov 1 19:27:57 MultiCrew apache2: PHP 3. fopen() /var/www/web/components/filemanager/class.filemanager.php:453
我也试过给/ components / filemanager和/class.filemanager.php文件夹/文件777权限，但没有解决它。
以下是ls -alh / var / var / www和/ var / www / web命令的结果
