How to Install Adagios on Clear Linux Latest

Adagios is an open-source web-based nagios configuration interface that makes nagios monitoring system more manageable. In this tutorial, we will show you how to install Adagios on Clear Linux Latest.

Prerequisites

• A machine running Clear Linux Latest.
• A sudo user.

Step 1: Update Your System

Before installing any packages, it's important to ensure your system is up-to-date. You can update your system with the following command:

sudo swupd update

Step 2: Install Dependencies

To install Adagios, we need Apache server, PHP, and Nagios to be installed on the system.

Run the following command to install dependencies:

sudo swupd bundle-add apache-php nagios

Step 3: Install Adagios

You can download the Adagios from its official website(http://adagios.org/) or clone the latest version from the repository.

Run the following command to clone the latest version:

git clone git://github.com/opinkerfi/adagios.git

Copy the Adagios files to the webserver document root:

sudo cp -R adagios /var/www/html/

Step 3.1: Install Additional Packages

Adagios requires Python and some Python modules like PyYAML, setuptools, and feedparser to be installed.

To install them, run the following command:

sudo pip3 install pyyaml feedparser setuptools

Step 4: Configure Nagios

Adagios depends on Nagios, so we need to configure Nagios first.

Step 4.1: Create a New Contact

Edit the nagios contacts file /etc/nagios/objects/contacts.cfg and add a new contact.

sudo vim /etc/nagios/objects/contacts.cfg

Add the following code at the bottom of the file:

define contact{
        contact_name    adagios
        use             generic-contact
        alias           Adagios Contact
        email           [email protected]
}

Step 4.2: Create a New Host Group

Create a new hostgroup and add it to /etc/nagios/objects/hostgroups.cfg file.

sudo vim /etc/nagios/objects/hostgroups.cfg

Add the following code at the bottom of the file:

define hostgroup {
        hostgroup_name  adagios-servers
        alias           Adagios Servers
}

Step 4.3: Create a New Service Group

Create a new servicegroup and add it to /etc/nagios/objects/servicegroups.cfg file.

sudo vim /etc/nagios/objects/servicegroups.cfg

Add the following code at the bottom of the file:

define servicegroup {
        servicegroup_name adagios-services
        alias            Adagios Services
}

Step 4.4: Enable Livestatus

Adagios uses the Livestatus module to access Nagios information via a socket.

Edit /etc/nagios/nagios.cfg and add the following lines at the bottom of the file:

# Livestatus socket
broker_module=/usr/lib64/nagios/livestatus.so /var/cache/nagios3/rw/live
broker_module=/usr/lib64/nagios/livestatus.so /tmp/live

Create a new directory for Livestatus socket:

sudo mkdir /var/cache/nagios3/rw
sudo chmod 2775 /var/cache/nagios3/rw
sudo chown -R nagios:nagios /var/cache/nagios3

Restart Nagios service to apply the changes:

sudo systemctl restart nagios

Step 5: Access Adagios

Once everything is configured, you can access Adagios using your web browser by navigating to http://your-server-ip/adagios.

You should see the Adagios login screen. Use the default credentials (username: admin, password: admin) to login to the Adagios web interface.

Conclusion

Congratulations! You have successfully installed Adagios and configured it with Nagios on Clear Linux Latest. You can now easily manage your Nagios monitoring system with Adagios.
