node_exporter deployment

- download link

https://github.com/prometheus/node_exporter/releases

- start up

In order to facilitate identification, I changed its port and compiled ./start.shtwo ./stop.shscripts to facilitate future startup. The statement is as follows:

vim ./start.sh

nohup ./node_exporter > ./startlog.log 2>&1 &

vim ./stop.sh

#!/bin/sh
echo "stop"
#!/bin/bash

PID=$(ps -ef | grep node_exporter | grep -v grep | awk '{ print $2 }')
if [ "${PID}" ]
then
    echo 'Application is stpping...'
    echo kill $PID DONE
    kill $PID
else
    echo 'Application is already stopped...'
fi

- configure prometheus

# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"
    static_configs:
      - targets: ["127.0.0.1:9090"]
        #labels:
