![]() ![]() Once you click that, if it comes back green, then you are ready to click the "Build Database" button.Performance monitoring in Linux system is a MUST and very important process. Once you do that, click the "Check Credentials" button. The "User" and "Password" should be all that is necessary to fill in here. Go ahead and click on the "Database" button. If you've been following along diligently, then you've got that saved in a safe place. You'll need the password that you set for the database user "librenms" earlier in the process. Our next button over is for the database. The first button on the left is for the pre-checks. There are four buttons beneath the LibreNMS logo. Assuming that these are all marked as green, then we should be able to continue. The IP of our lab machine is 192.168.1.140, so we need to navigate to the following address in a web browser to finish the install:Īssuming all is working correctly, you should be redirected to the pre-install checks. In our lab version, we've got no hostname setup so to finish the setup, we need to go to the web server by IP address. Now that we have all of the components installed and configured, our next step is to finish the installation via the web. First, we need to install the EPEL repository (Extra Packages for Enterprise Linux): We are assuming a fresh install, so we need to do a few things with the repositories before we can continue. If you prefer to use the latter, head up to the Librenms Install Instructions and follow the guide there. Before we begin, note that this installation procedure focuses on httpd, rather than nginx. These commands should be entered as the root user. Some trouble-shooting skills, including log monitoring, web testing, and more, are required.When the document says to save your changes and exit, this is done with SHIFT:wq! Throughout this document, the examples use the vi editor as mentioned.For this reason, the SELinux procedure has not been lab tested. While we have included the SELinux procedure in this document, the container that we are using in the lab does not include it by default.You'll just need to switch up the SNMP configuration and options on your devices to match up to v3. If you want to use SNMP v3, it is supported by LibreNMS and will work. ![]() Working knowledge of command-line tools, including text editors such as vi.Assumption: that you are able to execute commands as root or can sudo to do so.All commands assume a fresh install of Rocky Linux. A server or container (yes, LibreNMS will run in a container, however if you have a lot to monitor, your best bet would be to install on its own hardware) running Rocky Linux.Prerequisites, Assumptions and Conventions ¶ While the installation will pretty closely follow the official install instructions found here, we've added some explanation and even some minor changes, which make this procedure preferable to that excellent document. There are lots of other options for monitoring out there that this author has used before, Nagios and Cacti being two, but LibreNMS offers what those two projects offer individually, in one spot. This document will only get you started with LibreNMS, but we will point you to the project's excellent (and extensive) documentation to get you going further. There are many monitoring options out there, but one option that is very good and has many, if not all, of the monitoring components available under one roof, is LibreNMS. This can include graphing bandwidth usage at router end points, monitoring the up/down of services running on various servers, and much, much more. Network and systems administrators almost always need some form of monitoring.
