Quick Guide: How to Install Prometheus on Linux

Prometheus is an open-source monitoring and alerting toolkit. Follow these condensed steps to get your server up and running quickly.

1. Download & Prepare

Visit the Prometheus Downloads page. Download the latest Linux AMD64 binary and extract it:

Bash

wget https://github.com/prometheus/prometheus/releases/download/v2.x.x/prometheus-2.x.x.linux-amd64.tar.gz
tar -xvf prometheus-*.tar.gz

2. Setup User & Permissions

For security, create a dedicated user and setup directories for configuration and data storage:

Bash

sudo useradd --no-create-home --shell /bin/false prometheus
sudo mkdir /etc/prometheus /var/lib/prometheus
sudo chown prometheus:prometheus /etc/prometheus /var/lib/prometheus

3. Move Binaries & Configuration

Relocate the executable files and the default configuration file to standard paths:

Bash

sudo mv prometheus promtool /usr/local/bin/
sudo mv prometheus.yml /etc/prometheus/

4. Create Systemd Service

Create a service file at /etc/systemd/system/prometheus.service so Prometheus starts automatically. Point the ExecStart to your binaries and config file.

5. Start & Enable Service

Activate Prometheus using the following commands:

Bash

sudo systemctl daemon-reload
sudo systemctl enable --now prometheus

6. Access the Web UI
