It is a community-based fork of the Observium network monitoring tool. This tool is also a user-friendly monitoring system, it is easy to understand and use. It uses MySQL as its database backend and uses SNMP to discover remote clients. <\/p>\n\n\n\n<p>It supports a wide range of network hardware and operating systems including, FreeBSD, Cisco, Linux, HP, etc. In this tutorial, we will show you how to install and configure <a href=\"https:\/\/www.librenms.org\/\" target=\"_blank\" rel=\"noreferrer noopener\">LibreNMS <\/a>on Ubuntu 20.04.<\/p>\n\n\n\n<!--more-->\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_65 counter-hierarchy ez-toc-counter ez-toc-transparent ez-toc-container-direction\">\n<p class=\"ez-toc-title\">Table of Contents<\/p>\n<label for=\"ez-toc-cssicon-toggle-item-662f022c2518b\" class=\"ez-toc-cssicon-toggle-label\"><span class=\"ez-toc-cssicon\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/label><input type=\"checkbox\"  id=\"ez-toc-cssicon-toggle-item-662f022c2518b\"  aria-label=\"Toggle\" \/><nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.rosehosting.com\/blog\/how-to-install-and-configure-librenms-on-ubuntu-20-04\/#Prerequisites\" title=\"Prerequisites\">Prerequisites<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.rosehosting.com\/blog\/how-to-install-and-configure-librenms-on-ubuntu-20-04\/#Step-1-Log-in-to-the-server\" title=\"Step 1.

Additionally, replace \u2018root\u2019 with the username of the system user with sudo privileges.<\/p>\n\n\n\n<p>To check whether you have the proper Ubuntu version installed on your server, run the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">$ lsb_release -a<\/pre>\n\n\n\n<p>You should get an output like this:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">No LSB modules are available.<br>Distributor ID: Ubuntu<br>Description: Ubuntu 20.04.3 LTS<br>Release: 20.04<br>Codename: focal<\/pre>\n\n\n\n<p>Before starting, you have to make sure that all Ubuntu OS packages installed on the server are up to date. You can do this by running the following commands:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">$ sudo apt update -y<br>$ sudo apt upgrade -y<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"step-2-create-a-system-user\"><span class=\"ez-toc-section\" id=\"Step-2-Create-a-System-User\"><\/span>Step 2.

In this post, we will use Nginx instead of Apache.

Configure MariaDB and Create a Database<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Before creating a new database for LibreNMS, let&#8217;s modify our default MariaDB configuration file.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">$ sudo nano \/etc\/mysql\/mariadb.conf.d\/50-server.cnf<\/pre>\n\n\n\n<p>Add these lines to [mysqld] section<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">innodb_file_per_table=1<br>lower_case_table_names=0<\/pre>\n\n\n\n<p>Save the file then exit and restart MariaDB<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">$ sudo systemctl restart mysql<\/pre>\n\n\n\n<p>Once restarted, we can create a new database for LibreNMS installation. We need to log in to the MariaDB console and create a database for LibreNMS.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">$ sudo mysql<\/pre>\n\n\n\n<p>In MySQL shell, run these commands as shown below.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">MariaDB [(none)]&gt; CREATE DATABASE librenms CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;\nQuery OK, 1 row affected (0.000 sec)\n\nMariaDB [(none)]&gt; CREATE USER 'librenms'@'localhost' IDENTIFIED BY 'm0d1fyth15';\nQuery OK, 0 rows affected (0.000 sec)\n\nMariaDB [(none)]&gt; GRANT ALL PRIVILEGES ON librenms.* TO 'librenms'@'localhost';\nQuery OK, 0 rows affected (0.001 sec)\n\nMariaDB [(none)]&gt; FLUSH PRIVILEGES;\nQuery OK, 0 rows affected (0.000 sec)\n\nMariaDB [(none)]&gt; \\q<\/pre>\n\n\n\n<p>Make sure you create a strong database password, replace <strong>m0d1fyth15 <\/strong>in the command above with a stronger one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"step-6-configure-php-fpm\"><span class=\"ez-toc-section\" id=\"Step-6-Configure-PHP-FPM\"><\/span>Step 6.

Next, we need to change the PHP-FPM pool name in librenms.conf, open librenms.conf make the following changes.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">$ sudo nano \/etc\/php\/7.4\/fpm\/pool.d\/librenms.conf<\/pre>\n\n\n\n<p id=\"change-php-fpm-pool-name-www-to-librenms\">In that file, change PHP-FPM pool name [www] to [librenms].

Enable LNMS command completion<br>To enable LNMS command completion, we need to copy the executables, run the commands:<\/p>\n\n\n\n<pre id=\"sudo-ln-s-opt-librenms-lnms-usr-bin-lnms-sudo-cp-opt-librenms-misc-lnms-completion-bash-etc-bash-completion-d\" class=\"wp-block-preformatted\">$ sudo ln -s \/opt\/librenms\/lnms \/usr\/bin\/lnms<br>$ sudo cp \/opt\/librenms\/misc\/lnms-completion.bash \/etc\/bash_completion.d\/<\/pre>\n\n\n\n<p>b.
