Problem

I’m getting this error after migrating my laravel project to linux server, see error below

UnexpectedValueException: The stream or file "/opt/lampp/htdocs/testproject/storage/logs/laravel-2021-08-31.log" could not be opened in append mode: failed to open stream: Permission denied in file /opt/lampp/htdocs/testproject/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler.php on line 110

Solution

the error is that, Storage folder doesn’t have permission to write log files, you can run

 chmod -R o+w projectname/storage
 chmod -R o+w projectname/bootstrap

if you are using nginx then you need to use nginx user permission like below

sudo chown -R nginx:root storage
sudo chown -R nginx:root bootstrap

That’s All.
