Tutorial: Installing μlogger on Fedora CoreOS Latest

μlogger is a free and open-source logging solution that allows you to track your location, speed, altitude, and more with your smartphone by using the μlogger app. In this tutorial, we will go through the steps required to install μlogger on Fedora CoreOS Latest.

Prerequisites

Before we begin, ensure that you have the following:

• A running instance of Fedora CoreOS Latest
• An active internet connection
• A user account with sudo privileges

Step 1: Install the required dependencies

Before we can install μlogger, we need to install the required dependencies. Enter the following command to install the required packages:

sudo dnf install git make gcc postgresql-server postgresql-client

Step 2: Install the Postgres database

μlogger requires a Postgres database to store the data collected from the mobile app. We will install the server and client components of Postgres on our Fedora CoreOS instance. Enter the following command to do so:

sudo systemctl enable postgresql
sudo systemctl start postgresql
sudo systemctl status postgresql

Step 3: Clone the μlogger repository

We will now clone the μlogger repository from GitHub. Enter the following command to clone the repository:

git clone https://github.com/bfabiszewski/ulogger-server.git

Step 4: Open the Postgres CLI

We will now open the Postgres CLI to create a database and user for μlogger. Enter the following command to open the CLI:

sudo -i -u postgres
psql

Step 5: Create a database and user for μlogger

We will now create a database and user for μlogger. Enter the following commands to do so:

CREATE DATABASE ulogger;
CREATE USER ulogger WITH ENCRYPTED PASSWORD 'password';
GRANT ALL PRIVILEGES ON DATABASE ulogger TO ulogger;
\q
exit

Step 6: Install and configure μlogger

We will now install and configure μlogger. Enter the following commands:

cd ulogger-server
make install
cp sample.config config
vi config

In the config file, change the following values:

DB_URL="postgresql://ulogger:password@localhost/ulogger"

Step 7: Start μlogger

We will now start μlogger as a service. Enter the following command:

sudo systemctl enable --now ulogger
