“laravel.log” could not be opened: failed to open stream [duplicate]

Answer 1

If All Above suggestions not working disable your selinux and try again

Answer 2

All files and folders under app/storage should be writable by you and group www-data (the webserver).

Error in exception handler: The stream or file "laravel/app/storage/logs/laravel.log" could not be opened: failed to open stream: Permission denied in laravel/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler.php:77

If you get this error (or a similar error) in the browser when accessing your site, then the group www-data can't write to app/storage. If you get this error when you execute certain php artisan commands, then you (the user) can't write to app/storage. Therefore both you and the www-data group must have write permission.

---

To ensure the files and folders have the correct permissions:

1. Go to the root of your Laravel installation (where composer.json and artisan live).

2. Change the owning user and group, where yourusername is your username:

   sudo chown -R yourusername:www-data app/storage
   

   This recursively (-R) sets the user:group owners to yourusername:www-data in all files and folders from app/storage onward.

3. Add the write permission for both you and the www-data group:

   sudo chmod -R ug+w app/storage
   

   This recursively (-R) adds (+) the write flag (w) to the user (u) and group (g) that own the files and folders from app/storage onward.

4. Additionally, some suggest you may need to flush the application cache.

   php artisan cache:clear
   

5. Finally, you may want to regenerate Composer's autoload files.

   composer dump-autoload
   

Answer 3

im pretty new on laravel. May be I could not explain it in depth but that command fixed my problem.

chmod -R 777 storage/

Answer 4

As for me I had changed my storage permission with chmod -R 777 storage and it's work well.

However, setting 777 permissions is incredibly dangerous and should not be done on any server other than your local machine.

I had checked for this configuration at here.

Answer 5

If changing the file permissions as described in the other answers didn't work and you're using CentOS 7 or RHEL then the issue may be a security program called selinux. I struggled with all kinds of permissions and groups before noticing user3670777 answer to Laravel 4: Failed to open stream: Permission denied

Hope this helps others.

Answer 6

You need to run one of the following:

• sudo chmod -R 644 app/storage
• sudo chmod -R 755 app/storage
