Node Exporter 安装最佳实践

下载可执行文件 tar.gz

wget https://github.com/prometheus/node_exporter/releases/download/v1.8.2/node_exporter-1.8.2.linux-amd64.tar.gz

创建对应用户组、用户

sudo groupadd -f node_exporter
sudo useradd -g node_exporter --no-create-home --shell /bin/false node_exporter
sudo mkdir /etc/node_exporter
sudo chown node_exporter:node_exporter /etc/node_exporter

解压、安装 node_exporter

tar -xvf node_exporter-1.8.2.linux-amd64.tar.gz
mv node_exporter-1.8.2.linux-amd64 node_exporter-files
sudo cp node_exporter-files/node_exporter /usr/bin/
sudo chown node_exporter:node_exporter /usr/bin/node_exporter

创建 systemd 服务

sudo vim /usr/lib/systemd/system/node_exporter.service
