Modify the installation directory name to prometeus

cd /usr/local/
mv prometheus-2.37.6.linux-amd64/ prometheus

Start the prometeus service

cd prometheus

nohup ./prometheus --storage.tsdb.path="data/" --storage.tsdb.retention=30d --config.file=prometheus.yml > ./prometheus.log 2>&1 &

Parameter interpretation

--storage.tsdb.path="data/"  
                                 Base path for metrics storage. Use with server mode only.

--storage.tsdb.retention=STORAGE.TSDB.RETENTION  
                                 [DEPRECATED] How long to retain samples in storage. This flag has been deprecated, use "storage.tsdb.retention.time" instead. Use with server
                                 mode only.

--config.file="prometheus.yml"  
                                 Prometheus configuration file path.

Automatically generate data directory and prometheus.log file

4. Add auto-start at boot

4.1. Configure rc-local.service

In debian 10, add a custom command in /etc/rc.local to realize the automatic execution of the command when booting up: booting up automatically.

Debian 10 has the rc-local service installed by default, but it is not started, so there is no /etc/rc.local file by default.

The default rc-local service is not started.
systemctl status rc-local shows Active: inactive (dead) is not started.

The default rc-local.service file

starts the rc-local service
and fails to start because the condition verification fails, which means that there is no /etc/rc.local file on the system.

Then first create the /etc/rc.local file and give it executable permissions

touch /etc/rc.local
chmod +x /etc/rc.local 

Start the rc-local service again and report an error

systemctl start rc-local.service

/etc/rc.local format error

Edit the /etc/rc.local file and add a line: #!/bin/bash

vi /etc/rc.local

Start the rc-local service again

systemctl start rc-local.service

4.2. Add a custom startup command

Edit the /etc/rc.local file

vi /etc/rc.local

Add a line:

nohup /usr/local/prometheus/prometheus --storage.tsdb.path="/usr/local/prometheus/data/" --storage.tsdb.retention=30d --config.file=/usr/local/prometheus/prometheus.yml > /usr/local/prometheus/prometheus.log 2>&1 &

Restart the server to see if Prometheus is running

4.3. View rc-local.service

systemctl status rc-local.service

You can see that all self-starting services configured through /etc/rc.local are displayed in CGroup
