How to migrate laravel to server?

Question

Laravel

Hello. I can’t solve the problem with transferring laravel to the server in any way, I tried different options, namely
1) I copied everything from the public folder to "/www/mysite.com/tools/check-tag/" I make a microservice in the folder of one of the sites (on the server I have several sites in the public_html folder), so I copied it all and commented out these lines in .htaccess

<IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

then to the root of the server i.e. in a folder that is a level higher than "www" filled in a folder called laravel in which everything else was.
After that, I fixed the paths in "/www/mysite.com/tools/check-tag/index.php" to the correct ones (The paths are definitely correct because I thought that the problem was in them and checked everything manually, in general, it took me a long time to write how I did it did, but the paths are 100% correct) and after all this, when I try to access the site, I get HTTP ERROR 500, and in the server logs there are these lines

2) The second option is to simply move everything to "/www/mysite.com/tools/check-tag/" and add .htaccess with this content to the root

RewriteEngine On
RewriteCond %{REQUEST_URI} !^public
RewriteRule ^ public/index.php [L]

and in public/.htaccess just comment out Options -MultiViews Please help me

find a solution to this problem.
Ps if it's important - use ISP manager

Answer 1

It seems to me that different versions of php use the old place != new.
To avoid such problems + to make it more convenient to work and transfer, I recommend using Docker.
