1、下载及解压安装包

cd /usr/local/src/

export VER="0.18.1"
wget -N https://github.com/prometheus/node_exporter/releases/download/v${VER}/node_exporter-${VER}.linux-amd64.tar.gz

mkdir -p /data0/prometheus 
groupadd prometheus
useradd -g prometheus prometheus -d /data0/prometheus
 
tar -xvf node_exporter-${VER}.linux-amd64.tar.gz
cd /usr/local/src/
mv node_exporter-${VER}.linux-amd64 /data0/prometheus/node_exporter
 
chown -R prometheus.prometheus /data0/prometheus

2、创建node_exporter.service的 systemd unit 文件

• centos下创建服务

cat > /usr/lib/systemd/system/node_exporter.service <<EOF
[Unit]
Description=node_exporter
Documentation=https://prometheus.io/
After=network.target
 
[Service]
Type=simple
User=prometheus
ExecStart=/data0/prometheus/node_exporter/node_exporter
Restart=on-failure
 
[Install]
WantedBy=multi-user.target
EOF

• ubuntu下创建服务

cat > /etc/systemd/system/node_exporter.service <<EOF
[Unit]
Description=node_exporter
Documentation=https://prometheus.io/
After=network.target
 
[Service]
Type=simple
User=prometheus
ExecStart=/data0/prometheus/node_exporter/node_exporter
Restart=on-failure
 
[Install]
WantedBy=multi-user.target
EOF

3、启动服务

systemctl daemon-reload
systemctl stop node_exporter.service
systemctl enable node_exporter.service
systemctl restart node_exporter.service

4、运行状态

systemctl status node_exporter.service

5、客户监控端数据汇报
