0x00.前言

上次写还是18年的这篇文章：树莓派 3B 初始化，但是这次变成了树莓派 3B+ 初始化草

0x01.Raspberry Pi Imager.app烧录镜像

0x02.设置静态IP地址

搬家之后rpi-master和rpi-slave均不再使用无线连接（分别是5G和2.4G的WiFi），全部以菊花插网线的方式上网，因此需要修改/etc/dhcpcd.conf，末尾追加

0x05.安装SmokePing

参照How to install SmokePing全部得编译安装，看完直接劝退完全折腾不动，还是算了吧，真的需要一键安装脚本……
然后谷歌看到树莓派上有编译好的包，于是立即从cn-py-dl-c8切换到rpi-master来安装了
后来发现也可以用docker：https://github.com/linuxserver/docker-smokeping

Description: latency logging and graphing system
 SmokePing consists of a daemon process which organizes the
 latency measurements and a CGI which presents the graphs.
 .
 With SmokePing you can measure latency and packet loss in your network.
 SmokePing uses RRDtool to maintain a longterm datastore and to draw pretty
 graphs giving up to the minute information on the state of each
 network connection.
