  9. Create a new user called nagios with administrative privileges.<\/li>\n
  10. Create a new group called nagcmd.<\/li>\n
  11. Add the user “nagios” to the “nagcmd” group using the command “sudo usermod -a -G nagcmd nagios”.<\/li>\n
  12. Establish a password for the Nagios Web interface by executing the following command.<\/li>\n
  13. Create a new user named “nagiosadmin” in the file “\/usr\/local\/nagios\/etc\/htpasswd.users.”<\/li>\n
  14. Install Nagios plugins: Download Nagios plugins from the official website (https:\/\/www.nagios-plugins.org\/) and follow their installation instructions to set them up.<\/li>\n
