Installing Prometheus on CentOS 7

Prometheus is an open-source monitoring and alerting system that allows you to collect and store metrics from various systems and services. It provides a powerful query language, a flexible data model, and an easy-to-use web interface for visualizing and exploring collected data.

Here are the steps to install Prometheus on CentOS 7:

sudo yum update -y

sudo useradd -M -r -s /bin/false prometheus

cd /tmp wget https://github.com/prometheus/prometheus/releases/download/v2.33.1/prometheus-2.33.1.linux-amd64.tar.gz tar xvf prometheus-2.33.1.linux-amd64.tar.gz

sudo mv prometheus-2.33.1.linux-amd64/{prometheus,promtool} /usr/local/bin/ sudo mv prometheus-2.33.1.linux-amd64/{consoles,console_libraries} /etc/prometheus/

sudo chown -R prometheus:prometheus /usr/local/bin/{prometheus,promtool} sudo chown -R prometheus:prometheus /etc/prometheus/{consoles,console_libraries}

sudo nano /etc/prometheus/prometheus.yml

global:   scrape_interval: 15s  scrape_configs:   - job_name: 'prometheus'     scrape_interval: 5s     static_configs:       - targets: ['localhost:9090']

sudo nano /etc/systemd/system/prometheus.service
