Install/Configure Prometheus and Grafana

Because I am already familiar with Prometheus, some of my server software and small applications are usually monitored through Prometheus. I often build Prometheus environments, but I don't have a summary of them, so I need to run to various places to find the configuration (systemd, prometheus, nginx configuration, etc.). So recently I had a new environment and needed to rebuild it, so I took the opportunity to document the process of installing and configuring prometheus and grafana. Translated with (free version)

How Https Handshake

This is a stock article that has been around for two or three years, but I haven't released it because there's nothing special about it.
