|
|
|
|
Once you have completed the web installer steps. Please add the following to `config.php`
|
|
|

|
curl -o /usr/bin/distro https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/distro

chown -R librenms:librenms /opt/librenms

systemctl enable httpd

systemctl enable mariadb

```
|
|
|
|
Now run validate your install and make sure everything is ok:
|
|
|
|
```bash
|
|
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?
|
|
|
|
