利用Prometheus+Grafana可以轻松的搭建K8S集群监控系统，这套系统事实上也作为K8S监控的标准，本文借鉴了网上大量的文章资料并在他们的基础上总结所成。
说明: 文章中所使用的均为CentOS 7 操作系统
一. NFS文件服务器准备，用以存储Promethues和Grafana数据
1.安装NFS服务器（192.168.0.2）
yum -y install nfs-utils
systemctl enable nfs #开启自启动
systemctl start nfs #启动nfs服务2.创建共享目录
mkdir -p /data/nfs/{promethues,grafana,grafana}
chown -R 65534.65534 /data/nfs/promethues #这里非常重要，否则promethues无法启动，即便是设置了777权限也会报错
chmod 777 /data/nfs/{promethues,grafana,grafana} #这里需要打开所有用户可读写3.设置NFS共享
echo "/data/nfs *(rw,no_root_squash,async,insecure)">>/etc/exports
systemctl restart nfs4.查看共享
showmount -e 127.0.0.1
[root@nfsserv ~]# showmount -e 127.0.0.1
Export list for 127.0.0.1:
/data/nfs *二.安装 node-exporter
1. node-exporter.yaml
