Laravel get internal server error(500) on CentOS

I have laravel project that want to deploy on CentOS.

I have set DocumentRoot on Centos like this.(/etc/httpd/conf/httpd.conf)

DocumentRoot "/var/www/html/<laravel_app_name>/public"

But when I access to server, I got internal server error. The project works well on my local. Who has experience about this? Regards.
