Posted on January 27, 2022January 27, 2022 By nim No Comments on [Node exporter] Install node_exporter on Linux by a script file!

https://github.com/prometheus/node_exporter/releases
Bạn vào link trên để theo dõi các bạn release mới nhất:

File bên có thể bỏ vào file .sh và chạy

wget https://github.com/prometheus/node_exporter/releases/download/v1.3.1/node_exporter-1.3.1.linux-amd64.tar.gz
tar -xvzf node_exporter-1.3.1.linux-amd64.tar.gz
mv node_exporter-1.3.1.linux-amd64 /home/node_exporter
useradd -m -s /bin/bash prometheus

cat >>/etc/systemd/system/node_exporter.service<<EOF
[Unit]
Description=Node Exporter
Wants=network-online.target
After=network-online.target

[Service]
User=prometheus
ExecStart=/home/node_exporter/node_exporter
Restart=always
RestartSec=10s
NotifyAccess=all

[Install]
WantedBy=default.target
EOF

systemctl daemon-reload
systemctl start node_exporter
systemctl enable node_exporter

thực hiện check port:
netstat -ntlp

hiện như này là ok

xong vào file prometheus.yaml sửa file config

global:
  scrape_interval: 10s
scrape_configs:
  ######################node exporter linux
  - job_name: 'linux_exporter'
    static_configs:
    - targets:
      - 192.168.101.24:9100

thứ hiện reload prometheus
Mình cài prometheus nên mình reload theo kiểu các bạn cũng chưa thấy.

ps uax | grep prometheus
mình sử dụng số 933
kill -HUP 933
Như này là Prometheus đã collected metric of node_exporter
BareMetal, Prometheus
