This document explains how to install Adagios on different platforms. We recommend using redhat based platform because that is what the adagios developers use, so that one is tested the most.

The documentation assumes you want to use nagios as a monitoring engine. Adagios supports icinga and naemon equally well, but the documentation assumes nagios because that one is currently packaged by all the major distributions.

If you find any errors in these docs, please be so kind to either update the wiki or file an issue in the issue tracker.

Install Adagios and Naemon with Docker

If you want to try out Adagios we have 2 docker images available for testing. Feel free to send in feature request and issues. Images hosted on Docker Hub.

[DRAFT] Install Adagios, OKconfig and Naemon on Red Hat based systems - RHEL8 [DRAFT]

This chapter shows how to install Adagios from scratch on Red Hat, Centos or Fedora based machines.

# If you don't know how to configure SElinux, put it in permissive mode:
sudo sed -i "s/SELINUX=enforcing/SELINUX=permissive/" /etc/selinux/config
sudo setenforce 0

# First install the repositories needed for this setup
sudo rpm -Uvh "https://labs.consol.de/repo/stable/rhel8/i386/labs-consol-stable.rhel8.noarch.rpm"

# Enable EPEL
## RHEL/CentOS 8:
sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
## Additionally on RHEL 8
sudo subscription-manager repos --enable "codeready-builder-for-rhel-8-$(arch)-rpms"

## CentOS Stream 8:
sudo dnf install -y epel-release

# Install dependency packages

sudo yum install -y git acl mod_ssl git python36 python36-devel python3-pip python3-setuptools

Installing Adagios running on Naemon on RHEL 7 or CentOS 7

https://github.com/opinkerfi/adagios/wiki/Naemon-and-Adagios-Install-Guide

Installing from pip

If you are a python developer, or for some reasons the packages above do not work for you, adagios can be installed with pip by running the following command:

pip install django<=1.9 pynag adagios okconfig

or

pip install --install-option="--prefix=/opt/adagios" django<=1.9 pynag adagios okconfig

This assumes you already have a working monitoring environment and Nagios, Livestatus are already configured. Please consults the Red Hat or Debian guides on how to configure everything.

Configuration on non-standard set ups

If you install adagios from packages, it will assume that you are running Nagios from packages as well. If you have installed Nagios in a different location, or if you are using another monitoring core (Naemon, Icinga, Shinken, etc) there are a few things you need to configure.

Keep an eye our for the following, if you have non standard paths:

  • Adagios main config (/etc/adagios/adagios.conf) Make sure paths to nagios.cfg and the nagios binary are correct
  • Apache config file (/etc/httpd/conf.d/adagios.conf on rhel) - make sure adagios runs as a user that has access to the nagios.cfg file
