How To Install Nagios on Manjaro

Install Nagios on Manjaro

In this tutorial, we will show you how to install Nagios on Manjaro. Nagios is a powerful monitoring system that enables organizations to identify and resolve IT infrastructure problems before they affect critical business processes. For users of Manjaro Linux, an Arch-based distribution known for its user-friendliness and accessibility, installing Nagios can enhance system monitoring capabilities significantly.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Nagios monitoring system on a Manjaro Linux.


  • A server or desktop running one of the following operating systems: Manjaro, and other Arch-based distributions.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A stable internet connection is crucial for downloading and installing packages. Verify your connection before proceeding.
  • Access to a Manjaro Linux system with a non-root sudo user or root user.

Install Nagios on Manjaro

Step 1. Keep your system up-to-date to ensure compatibility with the latest software packages.

sudo pacman -Syu

This command synchronizes the package database and updates all installed packages to their latest versions.

Step 2. Installing Dependencies.

Nagios requires certain packages to be installed on your system. Install the necessary dependencies using the following command:

sudo pacman -S apache php gd openssl perl gcc make unzip bash-completion jwhois nmap apache php-apache

Step 3. Create a Nagios User and Group.

For security purposes, Nagios should not run as the root user. Create a dedicated user and group for Nagios:

sudo useradd -m -s /bin/false nagios
sudo groupadd nagcmd
sudo usermod -a -G nagcmd nagios
sudo usermod -a -G nagcmd http

Step 4. Installing Nagios on Manjaro

Download the latest version of Nagios Core from the official sources. You can find the download links on the GitHub page:

cd /tmp
tar xzf nagios-4.5.1.tar.gz

Compile the extracted source code and install Nagios:

cd /tmp/nagioscore-nagios-4.5.1
./configure --with-httpd-conf=/etc/httpd/conf.d \
--with-nagios-user=nagios --with-nagios-group=nagios --with-command-user=nagios
make all
sudo make install
sudo make install-init
sudo make install-config
sudo make install-commandmode

Set up the web interface for accessing Nagios through a browser:

sudo make install-webconf
sudo a2enmod rewrite cgi
sudo systemctl restart httpd

Next, secure the web interface by creating an administrative user:

sudo htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

Step 5. Download and Install Nagios Plugins.

Get the plugins for gathering system data:

cd /tmp
tar zxf release-2.4.8.tar.gz
cd /tmp/nagios-plugins-release-2.4.8
sudo make install

Check for errors before starting Nagios:

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Start Nagios and enable auto-start on reboot:

sudo systemctl start nagios
sudo systemctl enable nagios

Step 6. Accessing Nagios Web UI.

Access the web interface at http://your_ip/nagios. Login with username: nagiosadmin , password: nagios.
