Installation Nagios

Centos 8​

  • Ensure you have the epel-release repo
    • yum install epel-release
  • Install the main nagios package
    • yum install nagios
  • Install plugins if necessary (for us it is)
    • yum install nagios-plugins nagios-plugins-* --skip-broken
    • Note that several of the plugins covered by nagios-plugins-* require packages that do not seem to be easily available in Centos 8 yet. You could search for ways to install the dependencies manually, but we don't need those particular plugins so we can safely --skip-broken.
  • Note that this also installs httpd for you, as the main user interface for this service is a web-page.
