How to Install Adagios on Void Linux

Adagios is a web-based monitoring and alerting dashboard for Nagios. This tutorial will guide you through the steps required to install Adagios on Void Linux.

Prerequisites

Before you begin, please make sure you have the following:

  • A working Void Linux installation
  • Root access to your server
  • A web server installed (such as Apache or NGINX)
  • Nagios installed and configured

Step 1: Install Dependencies

First, we need to install some dependencies that are required by Adagios. Open your terminal and run the following command:

# xbps-install -S python3-pip python3-setuptools python3-devel py3-lxml py3-paramiko

This command will install the necessary package dependencies.

Step 2: Install Adagios

Next, we will install Adagios using pip. Run the following command:

# pip3 install adagios

This command will install Adagios from PyPI (Python Package Index).

Step 3: Configure Apache or NGINX

Adagios requires a web server to function properly. You can use either Apache or NGINX. In this tutorial, we will use Apache as an example.

Create a new Apache virtual host configuration file by running the following command:

# vi /etc/httpd/conf.d/adagios.conf

Add the following content to the file:

<VirtualHost *:80>
    ServerName adagios.example.com
    DocumentRoot /usr/local/share/adagios
    Alias /static /usr/local/share/adagios/static
    <Directory /usr/local/share/adagios/static>
        Require all granted
    </Directory>
    <Directory /usr/local/share/adagios>
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

Replace adagios.example.com with your own domain name. Save and close the file.

Step 4: Configuring Adagios

Adagios requires configuration for it to work correctly. Run the following command:

# adagios-conf wizard

Answer the questions as follows:

  • Nagios Configuration file [/etc/nagios/nagios.cfg]
  • URL for Nagios CGI [/cgi-bin/nagios3]
  • Apache configuration file for Adagios [/etc/httpd/conf.d/adagios.conf]
  • Path to stylesheets and javascript files [/usr/local/share/adagios/static]
  • Choose "Yes" to symlink Nagios config files to Adagios
  • Choose "Yes" to run Adagios exclusively with WSGI

After answering the questions, Adagios configuration will be created and written to /etc/adagios/adagios.conf.

Step 5: Run Adagios

Start the Adagios service using the following command:

# systemctl start adagios

Verify that the Adagios service is running by checking its status:

# systemctl status adagios

You should see a message that indicates the service is active and running.

Conclusion

Adagios is now installed and configured on your server. You can access it by navigating to http://adagios.example.com/ in your web browser. From here, you can manage and monitor your Nagios services easily.

Congratulations, you have successfully installed Adagios on Void Linux!
