Hi, im new at Linux and i have a small Motel where i want to install
 

Hello,

I'm new to Linux and I'm setting up a small motel where I want to install software for managing meeting room bookings. The best solution I've found so far is the Meeting Room Booking System (MRBS) because it's free and open source. I followed this tutorial: Meeting Room Booking System (MRBS) Installation for Linux (Ubuntu 22.04/Debian 12), but I'm encountering an issue where I can't access the booking system on the web. Instead, I only see the default Apache site, despite trying everything suggested in the tutorial. Can anyone help me with this?

System Background:
I'm running a Proxmox Server VE with a Debian container (LXC).

Thank you very much, lovely community, for any assistance you can provide.

TurnKey linux web site may offer some examples to use.

Here are some open-source hotel management systems:
HotelDruid
A free, web-based program that can manage bookings, inventory, availability, and rates for hotels with hundreds of rooms, bed and breakfasts, and vacation rentals
QloApps
A free, open-source system that can manage online and on-desk bookings, and includes a booking engine, hotel website, and property management system (PMS)
KWHotel Free
A hotel management system for small and midsize hospitality businesses
NOBEDS
A free hotel and hostel property management system for small and midsize hospitality businesses
Rezgo
A web-based reservation system that can integrate with popular booking engines like Expedia and Travel Advisor

First, check the log files. (Their location is in the VirtualHost config - there may also be generic Apache log files.)

Are you trying to access via domain name or IP address - either way have you confirmed they are correct, and not conflicting with another server and/or a default Apache site?

Despite what that tutorial claims, PPA repositories should NOT be used with Debian. This may or not be related to the issue, but might be worth seeing if anyone has written a Debian-specific tutorial.

Alternatively, follow a Debian-specific Apache-only tutorial for getting a site configured (probably one on Digital Ocean), verify it works, and then follow MRBS's own install guide instead.

Did you run the comnands
a2dissite and
a2ensite
as given in the tutorial?

I didn't read the question well did I?
