主程序 Node_exporter

• 单独下载连接
• 国内前置代理下载且安装一键代码(国内加速,安装路径/usr/local/node_exporter)

yum -y install wget && wget http://hk.2331314.xyz:5550/https://github.com/prometheus/node_exporter/releases/download/v1.3.1/node_exporter-1.3.1.linux-amd64.tar.gz && tar -zxvf node_exporter-1.3.1.linux-amd64.tar.gz && mv node_exporter-1.3.1.linux-amd64 /usr/local/node_exporter && rm -rf node_exporter-1.3.1.linux-amd64.tar.gz

把进程做成服务 自启动

cat >> /usr/lib/systemd/system/node_exporter.service << EOF

简单的优化

• 去除了很多用不到的指标，增加流畅度，只保留CPU、内存、硬盘、网络相关信息
