Laravel文件缓存：能否配置权限掩码使新缓存文件以664权限创建？

Got it, let's fix this permission issue you're facing with Laravel's cache files. You absolutely can configure the framework to generate new cache files with a 664 permission mask instead of the default 644—here's how to do it properly:

Step 1: Update Your Cache Configuration #

Open your config/cache.php file, find the file driver section (since you're using file-based caching), and add a new permission key set to 0664.

Your modified configuration block should look like this:

'file' => [
    'driver' => 'file',
    'path' => storage_path('framework/cache/data'),
    'permission' => 0664, // Add this line to set the desired permission mask
],

Important: Don't skip the leading 0 before 664—this tells PHP to treat the number as an octal value, which is required for correct permission handling. Omitting it will result in wrong permissions being applied.

Step 2: Fix Existing Cache Files #

The new permission setting only affects newly created cache files. To fix the existing 644 permission files that your shell user can't delete, run this command in your project root:

chmod -R g+w storage/framework/cache/data

This grants write access to the www-data group (which your shell user belongs to) for all existing cache files and directories.

A Quick Breakdown of 664 Permissions #

This permission mask gives exactly what you need:

• Owner (typically the web server's www-data user): Read and write access
• Group (your shell user is part of this): Read and write access
• Others: Read-only access

This setup lets both the web server process and your shell user manage cache files without permission conflicts.
