This tutorial will guide you on how to install Nagios on EndeavourOS Latest using the official Nagios download page.
Before installing Nagios, you will need to install some necessary packages. Open the terminal and execute the following command to install the required dependencies:
sudo pacman -S gcc glibc make openssl apache php gd net-snmp perl postgresql-libs
Next, you need to download the Nagios source code. Open the terminal and execute the following commands:
cd ~
curl -L -O https://github.com/NagiosEnterprises/nagioscore/archive/nagios-4.4.6.tar.gz
tar xzf nagios-4.4.6.tar.gz
After downloading the Nagios source code, you need to build and install it. Open the terminal and navigate to the extracted Nagios source directory:
cd nagioscore-nagios-4.4.6/
Then, run the following commands to compile and install Nagios:
sudo ./configure --with-httpd-conf=/etc/httpd/conf --with-command-group=nagcmd
sudo make all
sudo make install
sudo make install-init
sudo make install-commandmode
sudo make install-config
sudo make install-webconf
Nagios needs to be run as a dedicated user. Create the nagios user account and group by executing the following commands:
sudo useradd nagios
sudo groupadd nagcmd
sudo usermod -a -G nagcmd nagios
Next, you need to configure Nagios. Locate the Nagios configuration file (/usr/local/nagios/etc/nagios.cfg) and open it using your preferred text editor.
Uncomment the line that reads #cfg_dir=/usr/local/nagios/etc/servers by removing the # symbol, then save and close the file.
Create the directory for the configuration files by executing the following command:
sudo mkdir /usr/local/nagios/etc/servers
Nagios has a web interface for monitoring system metrics. You need to create an account to access the web interface.
Execute the following command to create a new web account named nagiosadmin:
sudo htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
Enter and confirm a password for the nagiosadmin user.
After completing all of the configurations, you can start the Nagios service. Execute the following command to start the service:
sudo systemctl start nagios.service
To verify that Nagios is working correctly, open a web browser and navigate to http://localhost/nagios. Log in using the credentials that you created in Step 6.
Once you have successfully logged in, you should see the Nagios Dashboard with various metrics and graphs.
Congratulations! You have successfully installed and configured Nagios on EndeavourOS Latest.
