拿了一个github的go采集namenode指标的项目，修改了一下，本地调测正常，记录一下在linux环境编译并运行的过程。
1.安装go环境
[root@hadoop1011 ~]# yum install go -y

2.尝试编译，发现失败
[root@hadoop1011 ~]# go build namenode_exporter.go
namenode_exporter.go:9:2: no required module provides package github.com/prometheus/client_golang/prometheus: go.mod file not found in current directory or any parent directory; see 'go help mo
dules'namenode_exporter.go:10:2: no required module provides package github.com/prometheus/log: go.mod file not found in current directory or any parent directory; see 'go help modules'
3. 更改GOPROXY依赖下载代理为国内的地址
[root@hadoop1011 ~]# go env

[root@hadoop1011 go_pkg]# go env -w GOPROXY=https://mirrors.aliyun.com/goproxy,direct

6.检测进程是否存在
[root@hadoop1011 go_pkg]# ss -tlnp|grep 9070
LISTEN 0 128 :::9070 :::* users:(("namenode_export",pid=4361,fd=3))
[root@hadoop1011 go_pkg]#
