Cron job
cp /opt/librenms/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 /opt/librenms/misc/librenms.logrotate /etc/logrotate.d/librenms
Set permissions
chown -R librenms:librenms /opt/librenms
setfacl -d -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
setfacl -R -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
Web installer
Now head to the web installer and follow the on-screen instructions.

http://librenms.example.com/install.php
The web installer might prompt you to create a config.php file in your librenms install location manually, copying the content displayed on-screen to the file. If you have to do this, please remember to set the permissions on config.php after you copied the on-screen contents to the file. Run:

chown librenms:librenms /opt/librenms/config.php
Final steps
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 the first device
We now suggest that you add localhost as your first device from within the WebUI.

Troubleshooting
If you ever have issues with your install, run validate.php as root in the librenms directory:

cd /opt/librenms
./validate.php
There are various options for getting help listed on the LibreNMS web site: https://www.librenms.org/#support
