Installing Observium on EndeavourOS Latest

Observium is a network monitoring tool that helps monitor the performance of all devices and networks in an organization. In this tutorial, we will take you through the steps required to install Observium on EndeavourOS Latest.

Prerequisites

  1. An instance of EndeavourOS Latest Running
  2. Server should have internet connectivity
  3. User with sudo privilege.

Step 1: Update the System

Before installing any packages, it is essential to ensure that your system is up to date. Run the commands below:

sudo pacman -Syu

Step 2: Install Required Packages

The following packages are required for Observium to function correctly. Install them on your system with the command below:

sudo pacman -S apache mariadb mariadb-clients php php-fpm net-snmp

Step 3: Create a Database for Observium

Observium requires a database to store system data. Run the following command to create a database for your Observium instance.

sudo mysql_secure_installation

Step 4: Download and Install Observium

Download the latest version of Observium from the official website:

wget http://www.observium.org/observium-community-latest.tar.gz -O observium.tar.gz

Next, extract the contents of the downloaded archive in the web server document root directory:

sudo tar zxvf observium.tar.gz -C /var/www/html/

Step 5: Create a Configuration File

Observium needs to be configured to connect to the database that we created earlier.

Navigate to the configuration directory and run the command below:

cd /var/www/html/observium/config/
sudo mv config.php.default config.php
sudo nano config.php

Edit the file appropriately and update the database details as shown below:

$config['db_extension'] = 'mysqli';
$config['db_host']      = 'localhost';
$config['db_user']      = '<database_username>';
$config['db_pass']      = '<database_password>';
$config['db_name']      = '<observium_database_name>';

Step 6: Configure Apache and PHP

Observium requires that PHP run as a separate process running on php-fpm.

Therefore, open the file "/etc/php/php.ini" and modify the following lines:

cgi.fix-pathinfo=0

Next, we’ll need to modify Apache configuration to add Observium as a virtual host.

Create a new Apache configuration file

sudo nano /etc/httpd/conf/extra/observium.conf

Add the following configuration to the file:

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot /var/www/html/observium/html/
    ServerName observium.example.com
    ServerAlias www.observium.example.com
    <Directory /var/www/html/observium/html/>
        Options FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
    ErrorLog /var/log/httpd/observium_error.log
    CustomLog /var/log/httpd/observium_access.log combined
</VirtualHost>

And enable PHP-FPM in Apache:

sudo nano /etc/httpd/conf/httpd.conf

Add the following line below the comment LoadModule mpm_event_module modules/mod_mpm_event.so:

LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so

Now restart apache

sudo systemctl restart httpd

Step 7: Access Observium Web Interface

You can now access Observium by launching your browser and entering the server hostname or IP address. 

http://<server_IP_address>/observium/

Conclusion

Observium has now been installed on your EndeavourOS Latest system with Apache Web Server and MariaDB database. With Observium, you can monitor your network and track the performance of all devices and connections.
