How to Install Adagios on Alpine Linux Latest

Introduction

Adagios is a frontend application that allows you to have a complete view of your Nagios and Icinga2 monitoring systems. In this tutorial, we will guide you through the process of installing Adagios on Alpine Linux Latest.

Prerequisites

Before we begin, make sure you have the following prerequisites:

• Alpine Linux Latest version installed on your system.
• Root access to the server.

Step 1: Update and upgrade the system

The first step is to update and upgrade the system packages to ensure that we have the latest versions of the dependencies.

apk update && apk upgrade

Step 2: Install the required packages

Next, we need to install the required packages for Adagios. Run the following command to install them:

apk add git apache2 libapache2-mod-wsgi python3 python3-dev py3-pip build-base

Step 3: Clone the Adagios repository

Now, we will clone the Adagios repository from Github. Run the following command to clone the repository:

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

Step 4: Install the required Python packages

Adagios require several Python packages that we need to install. To install the required packages, run the following command:

pip3 install -r /opt/adagios/requirements.txt

Step 5: Configure Apache for Adagios

To run Adagios using Apache, we need to configure Apache. First, we need to enable the wsgi module using the following command:

a2enmod wsgi

Next, we will create a new Apache virtual host for Adagios. Create the following file and save it as /etc/apache2/conf.d/adagios.conf:

WSGIScriptAlias / /opt/adagios/adagios/wsgi.py
WSGIPythonPath /opt/adagios/
WSGIDaemonProcess adagios python-path=/opt/adagios:/usr/lib/python3.8/site-packages
WSGIProcessGroup adagios

<Directory /opt/adagios/adagios>
    <Files wsgi.py>
        Require all granted
    </Files>
</Directory>

Step 6: Set up the Adagios database

Adagios uses a MySQL database to store its data. To set up the database, run the following commands:

apk add mariadb mariadb-client
/etc/init.d/mariadb setup
/etc/init.d/mariadb start
mysql_secure_installation
mysql -uroot -p

Enter the MySQL root password when prompted, then run these SQL commands to create a new database and a new user:

CREATE DATABASE adagios;
CREATE USER 'adagios'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON adagios.* TO 'adagios'@'localhost';
FLUSH PRIVILEGES;
exit;

Replace password with your desired password.

Next, we need to import the Adagios database schema. Run the following command:

mysql -uadagios -ppassword adagios < /opt/adagios/adagios/sql/mysql.sql

Step 7: Configure Adagios

Adagios's configuration is done through a configuration file located at /opt/adagios/adagios/conf/adagios.conf. We recommend that you only change the configuration file for your specific installation, and not the default one.

The most important configuration settings are the Nagios and Icinga setup settings. You need to specify the path to the nagios.cfg or icinga.cfg files. For Nagios, the configuration should look like this:

[nagios]
nagios_binary: /usr/sbin/nagios
cfg_file: /etc/nagios/nagios.cfg

For Icinga2, the configuration should look like this:

[icinga2]
icinga2_binary: /usr/sbin/icinga2
cfg_file: /usr/local/icinga2/etc/icinga2/icinga2.cfg

Step 8: Start the Adagios service

Now that everything is set up, we can start the Adagios service by running the following commands:

/etc/init.d/apache2 start

Conclusion

You have successfully installed Adagios on Alpine Linux Latest. You can now access Adagios at http://your_server_ip. If you encounter any issues during the installation, review the steps above or refer to the Adagios documentation for further help.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
