[sysadmin] requirements to set server for codeigniter app

Good days
English is not mi first language so lets say this whit goggle traductor help


I am the sysadmin in a small factory
one of the engineers hired a third party mostly un-experience underpaid bachelors to make a app
works on their test environment windows 8.1 64 whith xamp

Now we must set this app to run in a local virtualmachine whith
Centos 7, apache2, mariadb, php7
i do a clean install for this i create the database, database firewall and permissions are fine
SE disabled for the sake of the tests

we bring the app to the html folder anyway the app is not running
we figth with it all saturday morning but no luck

no they not know why
no i neither knows why

the error is :
https://127.0.0.1/produccion/login

Not Found
The requested URL /produccion/login was not found on this server.

soo i upload their app to a hosting we have in colombiahosting
and the app works there

no they not know why
no i neither knows why

for codeigniter all the knowledge i have come from the tutorials i read this Weekend
the bachelors knows some more but not enough


#####
No i cant le it there in the hosting it must run onsite in the factory
Anyway i think the culprit is the apache2 config, i enabled mod_rewrite and speling_module
but looks like something else is missing

the app was build on codeigniter '3.1.6'
What are the requirements tools or Apache mods needed for this to run ?
