Naemon is an open-source network monitoring system that derives from Nagios. It provides a robust monitoring solution for IT operations.
In this tutorial, we will guide you through the Naemon installation process on POP! OS latest.
Before starting with the installation process, make sure your system is updated to the latest version by running the following commands:
sudo apt update
sudo apt upgrade -y
Now, we need to install the prerequisites required for Naemon. Naemon uses Apache as a webserver, PHP scripting language, and some additional plugins.
You can install the prerequisites by running the following command:
sudo apt install apache2 php libgd-dev libapache2-mod-php libssl-dev php-gd snmp libcgi-pm-perl libnet-snmp-perl libmysqlclient-dev libdbi-perl libdbd-mysql-perl -y
The latest version of Naemon is available at its official website. You can download the tarball using the following command:
wget https://github.com/naemon/naemon/releases/download/1.0.12/naemon-1.0.12.tar.gz
Next, extract the downloaded tarball using the following command:
tar -xzvf naemon-1.0.12.tar.gz
Change to the extracted directory by running the following command:
cd naemon-1.0.12
Now, to build and install Naemon from the source, run the following commands:
./configure
make all
sudo make install
sudo make install-config
Once the installation is finished, validate the installation by running the following command:
naemon -v
If everything is installed correctly, the output should display the version number of Naemon.
Once the installation is complete, run the following command to create a new user group for Naemon:
sudo groupadd naemon
Next, create a system user and assign the user to the naemon user group using the following command:
sudo useradd -G naemon -m -s /bin/bash naemon
Set the ownership of the Naemon installation directory by running the following commands:
sudo chown -R naemon:naemon /usr/local/naemon/
Now, we need to configure Apache to serve Naemon's web-based interface. Here is a step-by-step guide:
Open the Apache configuration file using the following command:
sudo nano /etc/apache2/sites-available/naemon.conf
Copy and Paste the following code in the file:
<VirtualHost *:80>
DocumentRoot /usr/local/naemon/share/naemon/
AllowOverride None
<Directory /usr/local/naemon/share/naemon>
Options FollowSymLinks
AllowOverride None
Require all granted
</Directory>
</VirtualHost>
Enable the Apache rewrite module by running the following command:
sudo a2enmod rewrite
Enable the Apache site for Naemon by running the following command:
sudo a2ensite naemon.conf
Restart the Apache webserver using the following command:
sudo systemctl restart apache2
Now that Naemon is installed and configured, run the following command to start the Naemon service:
sudo systemctl start naemon
To enable Naemon to start at boot time, run the following command:
sudo systemctl enable naemon
That’s it! You have successfully installed Naemon on POP! OS. You can now log in to the web-based interface by opening a web browser and navigating to http://localhost/naemon.
From here, you can manage and monitor all the hosts and services.
Note that this tutorial only covers the basic installation of Naemon. In order to utilize its full potential, you may need to do further configurations depending on your requirements.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
