（2）node_exporter部署監控容器主機

監控容器伺服器CPU、記憶體、磁盤、I/O等資訊，首先需要安裝node_exporter。node_exporter的作用是用于機器系統資料收集。

（1）下載下傳node_exporter

https://prometheus.io/download/

shell> cd /Download/

shell> wget https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz

（2）解壓安裝

shell> tar -xvf node_exporter-0.18.1.linux-amd64.tar.gz

shell>cd node_exporter-0.18.1.linux-amd64

shell> mv node_exporter-0.18.1.linux-amd64 node_exporter

shell> chown -R prometheus.prometheus node_exporter

shell> systemctl restart node_exporter

shell>systemctl status node_exporter

shell>netstat -tunlp | grep node_exporter

（3）建立systemd服務

shell>cat > /etc/systemd/system/node_exporter.service << EOF

EOF

shell>systemctl daemon-reload

shell> systemctl start node_exporter #啟動node_exporter服務

shell> systemctl status node_exporter
