Fluentd is an open-source data collector designed to unify logging infrastructure. It can collect logs from various sources, process them, and send them to different destinations like Elasticsearch, Amazon S3, or PostgreSQL. In this tutorial, we will guide you through the process of installing Fluentd on Elementary OS Latest.
Before beginning with the installation of Fluentd, ensure the following prerequisites are met:
The first step is to install the packages required for Fluentd to work correctly. Fluentd requires Ruby and some dependencies to operate. Run the following command in your terminal to install the required packages:
sudo apt-get install -y ruby-dev make build-essential libssl-dev zlib1g-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev libffi-dev
The next step is to install Fluentd. To do this, follow the steps below:
Install the GPG key for Fluentd:
curl -sSL https://packages.treasuredata.com/GPG-KEY-td-agent | sudo apt-key add -
Add Fluentd repository to the package source list:
echo "deb https://packages.treasuredata.com/3/ubuntu/focal/ focal contrib" | sudo tee /etc/apt/sources.list.d/treasure-data.list
Note: Replace "focal" with your Elementary OS latest release codename
Update the package list:
sudo apt-get update
Install Fluentd:
sudo apt-get install -y td-agent
To start Fluentd, run the following command in Terminal:
sudo systemctl start td-agent
After starting Fluentd, verify the status of Fluentd by running:
sudo systemctl status td-agent
If Fluentd is running correctly, you should see output similar to this:
