Recovering from PHP update

Not sure how I got here, but I have a mysql error that I have been working on and am stuck.
I did try to change the database password.

[[email protected] ~]$ ./validate.php

Did you edit your credentials in both .env and config.php ?

and you can connect fine using them on mysql command line

I don’t have a .env file…Do I just create one? Is it in /opt/librenms ?

Sounds similar to this File .env not generated

you could try run ./scripts/composer_wrapper.php install --no-dev as librenms user

OK looking better
I was able to get the mysql table issues resolved

Currently ./validate .php works but ./daily fails

[[email protected] ~]$ ./

it looks like one of the processes it is using an old password

Doctrine\DBAL\Driver\PDOConnection->__construct(‘mysql:host=127…’, ‘librenms’, ‘OLD-password’, Array)
are the passwords from config.php or .env cached?

in /opt/librenms you could try:

php artisan config:clear
php artisan cache:clear

how did you generate your .env file in the end?

I found one issue, I had modified the config.php file and modified the $config[‘db_host’] = ‘’; with the host name of the box. I put the loopback adress back.

Its better, but I am getting the 502 Bad Gateway nginx/1.12.2 error on the web page.

Check for errrors in logs/librenms.log then.
