Installation Issue on GUI level (php8.1)

Help
1

Hi all

I’m trying to setup the product since yesterday.
Yesterday, using the old setup instructions still based on php7.4,
I was able to reach the web GUI showing the pre-check page,
where a message inform about the necessity to use php8.1 version.

Today I repeated the procedure, which is updated including the php8.1.
The ngingx and fpm services are starting (apparently) properly,
but I can’t gain the access to the web GUI to complete the installation.

The following error banner appeared.

librenms_error

Here below some logs.
Could someone help me please ?
Thanks in advance
I.

You have configured invalid credentials to the database

Hi

thanks for the reply.
I just put a new password at this level of the DB installation procedure :

CREATE USER 'librenms'@'localhost' IDENTIFIED BY 'password';

I used a simple alphanumeric combination, no special characters.
After that I never used that password, no prompt asked to insert it (no GUI access).
How can be invalid that passwd?
Thanks again for your time
I.

Hi again

I just finished a new fresh-install on another VM, directly based on PHP8.1 as reported into the new install guide, and everything goes fine.
Probably the upgrade from the previous version 7.4 to the new 8.1 introduced the issue on my old installation attempt.
Now I correctly reached the GUI installation section where I was asked to insert the DB credentials,
and the setup finished.
Thanks, regards
I.
