"laravel.log" could not be opened: failed to open stream
提问by Josh Mountain
I have setup Laravel homestead on a local OSX machine, everything seemed to be going smoothly until I tried to open example.app:8000 and got this error:
我在本地 OSX 机器上设置了 Laravel homestead，一切似乎都很顺利，直到我尝试打开 example.app:8000 并出现此错误：
Error in exception handler: The stream or file "/home/vagrant/Code/example/app/storage/logs/laravel.log" could not be opened: failed to open stream: Protocol error in /home/vagrant/Code/example/bootstrap/compiled.php:8671
I followed the Laravel docs as well as a Laracast about setting up homestead, so I am not sure what would be causing this. I can see that /home/vagrant/Code/example/app/storage/logs/laravel.logdoesn't exist, but I assume that is something that should be created automatically?
我遵循了 Laravel 文档以及关于设置宅基地的 Laracast，所以我不确定是什么导致了这种情况。我可以看到它/home/vagrant/Code/example/app/storage/logs/laravel.log不存在，但我认为应该自动创建它？

You need to run one of the following:

All files and folders under app/storageshould be writableby you and group www-data(the webserver).
您和www-data组（网络服务器）下的所有文件和文件夹app/storage都应该是可写的。
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
异常处理程序中的错误：无法打开流或文件“laravel/app/storage/logs/laravel.log”：无法打开流：laravel/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler 中的权限被拒绝.php:77
If you get this error (or a similar error) in the browser when accessing your site, then the group www-datacan't write to app/storage. If you get this error when you execute certain php artisancommands, then you (the user) can't write to app/storage. Therefore both you and the www-data group must have write permission.
如果您在访问您的网站时在浏览器中收到此错误（或类似错误），则该组www-data无法写入app/storage. 如果您在执行某些php artisan命令时遇到此错误，则您（用户）无法写入app/storage. 因此，您和 www-data 组都必须具有写入权限。
To ensure the files and folders have the correct permissions:
要确保文件和文件夹具有正确的权限：
Go to the root of your Laravel installation (where
composer.jsonandartisanlive).Change the owning user and group, where
yourusernameis your username:sudo chown -R yourusername:www-data app/storageThis recursively (
-R) sets the user:group owners toyourusername:www-datain all files and folders fromapp/storageonward.Add the write permission for both you and the
www-datagroup:sudo chmod -R ug+w app/storageThis recursively (
-R) adds (+) the write flag (w) to the user (u) and group (g) that own the files and folders fromapp/storageonward.Additionally, some suggest you may need to flush the application cache.
php artisan cache:clearFinally, you may want to regenerate Composer's autoload files.
composer dump-autoload
转到你的 Laravel 安装的根目录（where
composer.jsonandartisanlive）。更改拥有用户和组，
yourusername您的用户名在哪里：sudo chown -R yourusername:www-data app/storage这递归地 (
-R) 将 user:group 所有者设置为yourusername:www-data从app/storage以后的所有文件和文件夹中。为您和
www-data组添加写入权限：sudo chmod -R ug+w app/storage这递归地 (
-R) 添加 (+) 写入标志 (w) 到拥有文件和文件夹的用户 (u) 和组 (g)app/storage。此外，有些人建议您可能需要刷新应用程序缓存。
php artisan cache:clear最后，您可能希望重新生成 Composer 的自动加载文件。
composer dump-autoload

As for me I had changed my storage permission with chmod -R 777 storageand it's work well.
至于我，我已经更改了我的存储权限，chmod -R 777 storage并且运行良好。
However, setting 777 permissions is incredibly dangerous and should not be done on any server other than your local machine.
但是，设置 777 权限非常危险，不应在本地计算机以外的任何服务器上进行。
I had checked for this configuration at here.
我已经在这里检查了这个配置。

You can do this by following steps
您可以按照以下步骤执行此操作
chmod -R 775 storage
which means
意思是
7 - Owner can write
7 - Group can write
5 - Others cannot write!
If your webserver is not running as Vagrant, it will not be able to write to it, so you have 2 options:
如果您的网络服务器不是作为 Vagrant 运行，它将无法写入，因此您有 2 个选择：
chmod -R 777 storage (do not do this)
or change the group to your webserver user, supposing it's www-data:
或者将组更改为您的网络服务器用户，假设它是 www-data：
chown -R vagrant:www-data storage

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
如果按照其他答案中的描述更改文件权限不起作用，并且您使用的是 CentOS 7 或 RHEL，那么问题可能是名为 selinux 的安全程序。在注意到 user3670777 对Laravel 4 的回答之前，我一直在努力处理各种权限和组：无法打开流：权限被拒绝
Hope this helps others.
希望这对其他人有帮助。

If All Above suggestions not working disable your selinux and try again
如果以上所有建议都不起作用，请禁用您的 selinux 并重试
