设置为系统服务
vi /etc/systemd/system/node_exporter.service
\[Unit\] Description=node-exporter \[Service\] Type=simple Restart=on-failure RestartSec=5 ExecStart=/usr/local/node\_exporter/node\_exporter \[Install\] WantedBy=multi-user.target
启动:
systemctl start node_exporter systemctl status node_exporter systemctl enable node_exporter
配置prometheus
在prometheus.yml上新增监控节点:
- job_name: 'my-home-linux' static_configs: - targets: - 'localhost:9100'
重启prometheus,即可看到服务器信息
