# Laravel 部署：文件夹权限

问 `Laravel` 部署后，哪些文件夹需要写权限？

答 `storage` 目录包含编译后的 `Blade` 模板、`session` 会话生成的文件、缓存文件以及框架生成的其他文件。\
\
这个目录被细分成 `app` 、 `framework` 和 `logs` 三个子目录：

`app` 目录可以用来存储应用生成的任何文件；\
 `framework` 目录用来存储框架生成的文件和缓存； \
`logs` 目录包含应用的日志文件。 \
\
如果 `storage` 目录的权限不正确，可能导致应用运行出现异常，例如出现：

`The stream or file "/var/www/storage/logs/laravel.log" could not be opened: failed to open stream: Permission denied`

所以 `storage` 需要读写权限，设置如下：<br>

方法一 更改 `storage` 文件夹权限 `chmod -R 0755 storage` \
\
更改 `storage` 文件夹拥有者与 `php-fpm.conf` 运行用户一致，如 `php-fpm.conf` 配置为

```php
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
user = www-data
group = www-data
```

则命令为  `chown -R www-data:www-data storage`\
\
方法二更改 `storage` 文件夹权限为 `chmod -R 0777 storage`\
\
注意

生产服务器上应该遵循「最小权限原则」，推荐使用「方法一」
