How to Install Adagios on OpenSUSE Latest

Adagios is a web-based Nagios configuration interface that greatly simplifies the process of monitoring your network. In this tutorial, we will walk you through the steps required to install Adagios on OpenSUSE Latest.

Prerequisites

Before installing Adagios, make sure you have:

• A server running OpenSUSE Latest
• Root access to the server
• A working installation of Nagios

Step 1: Install dependencies

Adagios requires several dependencies to function properly, so the first step is to install them.

To do this, open a terminal and enter the following command:

sudo zypper install apache2 python python-pip python-setuptools python-devel python2-virtualenv graphviz graphviz-doc

This command will install Apache2, Python, pip, setuptools, development tools, the Graphviz library, and the Graphviz documentation.

Step 2: Install Adagios

Once you have all the dependencies, you can proceed to install Adagios.

First, create a virtual environment for Adagios by entering the following command:

sudo virtualenv /opt/adagios

Next, activate the virtual environment with:

source /opt/adagios/bin/activate

Now that you’re in the virtual environment, you can proceed to install Adagios by entering the following command:

sudo pip install Adagios

Step 3: Configure Adagios

Once you have installed Adagios, you need to configure it.

To do this, create a new Apache virtual host by creating a new configuration file in the /etc/apache2/vhosts.d/ directory. For example, if you want to create a virtual host named adagios.example.com, you can create a file called adagios.conf with the following content:

<VirtualHost *:80>
    ServerName adagios.example.com

    DocumentRoot /opt/adagios/share/adagios/htdocs
    ErrorLog /var/log/apache2/adagios_error_log
    CustomLog /var/log/apache2/adagios_access_log combined

    WSGIDaemonProcess adagios processes=2 threads=15 display-name=%{GROUP}
    WSGIProcessGroup adagios
    WSGIScriptAlias / /opt/adagios/share/adagios/wsgi/adagios.wsgi

    <Directory /opt/adagios/share/adagios/htdocs>
        Options FollowSymLinks
        AllowOverride All
    </Directory>
</VirtualHost>

Make sure to update the ServerName directive to match your domain name.

Once you’ve created the configuration file, enable the new virtual host by running the following command:

sudo a2ensite adagios.conf

Finally, reload Apache to apply the changes:

sudo systemctl reload apache2

Step 4: Access Adagios

Now that you’ve installed and configured Adagios, you can access it by visiting the URL of your new virtual host, in our example adagios.example.com.

Conclusion

In this tutorial, we’ve shown you how to install and configure Adagios on OpenSUSE Latest. With Adagios, you can easily manage and monitor your Nagios installation via a web interface.
