CentOS/Redhat安裝node_exporter
CentOS/Redhat安裝node_exporter
注：CentOS/Redhat 5會報kernel太老
node_exporter下載網址：
https://prometheus.io/download/
node_exporter-0.16.0.linux-amd64.tar.gz
我這邊以/home示例，請根據實際情況具體調整
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 （如果沒搭建本地yum，可自行下載適配的rpm包手動安裝）
