I try to configure librenms to send email but still issues .
First you need to solve your missing PHP module. Seems you’ve not installed the PHP-XML module.
./validate must be clean before going further.
Thank you “FTBZ” for reply , How to solve it PHP-XML module ?
I’m not an Ubuntu expert, but probably by this command:
apt install php7.0-xml
Ok i going to do it now .
step1
apt install php7.0-xml
step2
systemctl restart php7.0-fpm.service
systemctl reload php7.0-fpm.service
./validate.php
The database issue is not important, you can run the query.
Watch query can i run it ?
Run it in a mysql prompt:
mysql -u librenms -p librenms
Then enter the mysql password from config.php.
As for mail not sending, create a rule that would trigger then use the test scripts we have: https://docs.librenms.org/#Alerting/Testing/
