本文说明：go build 编译 prometheus、promtool
#环境：go1.11及以上版本
#下载最新源码：[https://github.com/prometheus/prometheus](https://github.com/prometheus/prometheus)
cd ${yourPath}/prometheus
rm -rf vendor
#编译得到 prometheus
go build ./cmd/prometheus
#编译得到 promtool
go build ./cmd/promtool
#done
touch ./conf/prometheus.yml
./prometheus --config.file="./conf/prometheus.yml"
Mark：
- 若直接在 ${yourPath}/prometheus 下执行 go build，报错：
can't load package: package github.com/prometheus/prometheus: unknown import path "github.com/prometheus/prometheus": cannot find module providing package github.com/prometheus/prometheus
main 不在这里(￣ε(#￣)☆╰╮(￣▽￣///)
- 可访问 google.golang.org，或者配置可用的 GOPROXY.
