DB Schema | Not Connected and Database | Not Connected after php81 upgrade

[mvoity]

hello,

after upgrading on 2 other server with no issue, my third server throws problems.

1. the ‘my.cnf’ files was empty, fixed that with the ‘my.cnf.rpmsave’ backup
2. .env file is fine
3. permissions are correct in all directory’s as i ran -

sudo chown -R librenms:librenms /opt/librenms
sudo chmod -R ug=rwX /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
sudo setfacl -d -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/

4. Database appears to be intact, i ran a repair and all is “ok”

here is output of ‘validate.php’

In config.php line 44:

line 44 of /opt/librenms/config.php -
$config[discovery_modules][discovery-arp] = 1;

what am i missing?
I stalked around for a similar issue and none of those fixes helped.

Thanks in advance

line 44 of /opt/librenms/config.php -
$config[discovery_modules][discovery-arp] = 1;

That should be quoted I’d have thought - are the other things in config.php quoted?

$config['discovery_modules']['discovery-arp'] = 1;

Cut and paste it from here if unsure: Discovery Support - LibreNMS Docs

Thank you, that fixed it. missing the single quote.

Thanks!
