Laravel installing in server (php artisan serve not working)

Hi All, I am totally new to laravel. I wanted to install latest laravel i.e., 5.2.* in 1and1 server . However 1and1 linux shared hosting provides php5.5.38 so I installed laravel 5.0.* in the server following the instruction provided in

http://carlorodriguez.github.io/blog/2016/01/29/deploy-laravel-webapp-to-1and1/

The frame work is installed as I can see all the folders necessary. I wanted to test if it is working by running the command php5.5 artisan serve it does not run continuously it says:

Laravel development server started on http://localhost:8000/ Error in argument 1, char 2: option not found S X-Powered-By: PHP/5.5.38 Content-type: text/html Usage: php5.5 [-q] [-h] [-s] [-v] [-i] [-f ] php5.5 [args...]

I expect the Laravel development server started on http://localhost:8000/ running in the server until I press crtl+c. If I use php5.5 artisan up it says ‘Application is now live’, but I can’t see anything in locahost:8000 am I checking the wrong URL?? I have not changed any url in the installed laravel project I have also tried different command like

php5.5 -s localhost:8000 -t public which shows

Status: 404 Not Found X-Powered-By: PHP/5.5.38 Content-type: text/html No input file specified.

Is there any other command to check laravel. Note: I was using php5.5 in all the command because the default php version in 1and1 linux shared server is 4.4.9 Sorry if I am asking silly questions I am new to laravel. Thanks in advance. I would really appreciate your help.
