Nagios is an open-source monitoring and alerting software used to monitor servers, network devices, applications, and services. In this tutorial, we will guide you through the steps to install Nagios on the latest version of Fedora Server.
Before we begin with the installation process, ensure that you have the following prerequisites:
It is recommended to update the system to the latest packages before installing any new package. To update the system, open the terminal and run the following commands:
sudo dnf update
sudo dnf upgrade
This will update the system packages to the latest version.
Before installing Nagios, we need to install some dependencies required for Nagios. To do this, run the following command:
sudo dnf install -y gcc glibc glibc-common wget httpd php gd gd-devel perl postfix
This will install all the required dependencies for Nagios.
Now we can proceed with downloading and installing Nagios from the official website. To download the latest version of Nagios, run the following command:
wget https://assets.nagios.com/downloads/nagioscore/releases/nagios-4.4.6.tar.gz
After downloading the Nagios package, extract it using the following command:
tar -zxvf nagios-4.4.6.tar.gz
Now navigate to the Nagios extracted directory:
cd nagios-4.4.6
Before installation, we need to configure the Nagios by running the following command:
./configure --with-httpd-conf=/etc/httpd/conf.d
This will configure the Nagios to use the default Apache web server.
After configuring, run the following command to install Nagios:
make all
sudo make install
sudo make install-init
sudo make install-commandmode
sudo make install-config
sudo /usr/bin/install -c -m 644 sample-config/httpd.conf /etc/httpd/conf.d/nagios.conf
Above commands will install the Nagios on your Fedora server.
To access the Nagios web interface, we need to create a user and password for Nagios. Run the following command to create a new user for Nagios:
sudo htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
It will ask you to set a password for the user.
Now we can configure the Nagios web interface by editing the Apache configuration file.
Open the Nagios configuration file using your favorite text editor:
sudo vi /etc/httpd/conf.d/nagios.conf
Replace the following lines:
Order deny,allow
Deny from all
Allow from 127.0.0.1
with:
Require all granted
Save and close the file.
Now restart the Apache web server using the following command:
sudo systemctl restart httpd
Open any web browser and navigate to the following URL:
http://your-server-IP/nagios/
Enter the username and password that you created earlier.
Now you can access the Nagios console and start monitoring your network devices, servers, applications, and services.
