Restart Web server
systemctl restart nginx
Web installer
Now head to: http://librenms.example.com/install.php and follow the on-screen instructions.
Once you have completed the web installer steps. Please add the following to config.php
$config['fping'] = "/usr/sbin/fping";
Configure snmpd
cp /opt/librenms/snmpd.conf.example /etc/snmp/snmpd.conf
vim /etc/snmp/snmpd.conf
Edit the text which says RANDOMSTRINGGOESHERE
and set your own community string.
curl -o /usr/bin/distro https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/distro
chmod +x /usr/bin/distro
systemctl restart snmpd
Cron job
cp librenms.nonroot.cron /etc/cron.d/librenms
Copy logrotate config
LibreNMS keeps logs in /opt/librenms/logs
. Over time these can become large and be rotated out. To rotate out the old logs you can use the provided logrotate config file:
cp misc/librenms.logrotate /etc/logrotate.d/librenms
Final steps
chown -R librenms:librenms /opt/librenms
systemctl enable nginx mariadb
Run validate.php as root in the librenms directory:
cd /opt/librenms
./validate.php
That's it! You now should be able to log in to http://librenms.example.com/. Please note that we have not covered HTTPS setup in this example, so your LibreNMS install is not secure by default. Please do not expose it to the public Internet unless you have configured HTTPS and taken appropriate web server hardening steps.
Add first device
We now suggest that you add localhost as your first device from within the WebUI.
What next?
Now that you've installed LibreNMS, we'd suggest that you have a read of a few other docs to get you going:
Closing
We hope you enjoy using LibreNMS. If you do, it would be great if you would consider opting into the stats system we have, please see this page on what it is and how to enable it.
