注：CentOS/Redhat 5会报kernel太老

node_exporter下载网址：

https://prometheus.io/download/

node_exporter-0.16.0.linux-amd64.tar.gz

我这边以/home示例，请根据实际情况具体调整

CentOS 7：

tar zxfv node_exporter-0.16.0.linux-amd64.tar.gz -C /home/

mv /home/node_exporter-0.16.0.linux-amd64 /home/node_exporter

vi /etc/systemd/system/node_exporter.service

[Unit]
Description=Prometheus Node Exporter
After=network.target

[Service]
ExecStart=/home/node_exporter/node_exporter
User=nobody

[Install]
WantedBy=multi-user.target

:wq

systemctl start node_exporter

systemctl enable node_exporter

CentOS 6：

tar zxfv node_exporter-0.16.0.linux-amd64.tar.gz -C /home/

mv /home/node_exporter-0.16.0.linux-amd64 /home/node_exporter

yum install daemonize （如果没搭建本地yum，可自行下载适配的rpm包手动安装）

useradd prometheus -s /sbin/nologin

mkdir /var/log/prometheus

mkdir /var/rum/prometheus

chown prometheus:prometheus /var/log/prometheus -R

chown prometheus:prometheus /var/run/promethus -R
