Laravel 5刀片无法在CentOS 7上工作

我尝试在Centos7上安装一个新的laravel项目Apache/PHP 5.6/MariaDB.

关于/var/www:

composer create-project laravel/laravel devil
chmod -R 777 devil/storage
chmod -R 777 devil/vendor

当我试图从浏览器访问它时，它似乎是刀片扩展不起作用。它一直显示空白页，没有任何错误。

我检查了chrome web开发人员扩展上显示500（内部服务器错误）的HTTP响应。

只有当我根本不使用blade模板（不使用.blade.php扩展和blade语法）时，该应用程序才能工作。

以下是文件夹结构

.env file（不变）

我使用IP地址(100.255.XXX.XXX)使用apache虚拟主机访问我的应用程序。下面是我的/etc/httpd/conf/httpd.conf。

...
#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#
ServerName 100.255.XXX.XXX
...
<VirtualHost *:80>
        ServerName 100.255.XXX.XXX
        DocumentRoot /var/www/devil/public
        <Directory /var/www/devil>
            AllowOverride All
        </Directory>
</VirtualHost>

请帮忙，谢谢。
