技术笔记

建议软件包安装，二进制安装请自行解决配置问题，docker安装需考虑网络问题。

linux 软件包直接部署

apt install prometheus-blackbox-exporter

二进制部署

# 下载安装
wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.23.0/blackbox_exporter-0.23.0.linux-amd64.tar.gz
tar -xvf  blackbox_exporter-0.23.0.linux-amd64.tar.gz
mv blackbox_exporter-0.23.0.linux-amd64/ /usr/local/blackbox_exporter
