Environment
nfs
K8s 集群正常
内网地址(nfs地址)：172.31.189.239
服务采用NodePort的暴露形式
install and set nfs
#安装依赖包
yum -y install nfs-utils rpcbind
#开机启动,
systemctl enable rpcbind.service
systemctl enable nfs-server.service
systemctl start rpcbind.service #端口是111
systemctl start nfs-server.service # 端口是 2049
# 创建一个/data/pvdata的共享目录
# mkdir /data/pvdata
chown nfsnobody:nfsnobody /nfs3/grafana/data
# cat /etc/exports
/nfs3/grafana/data 172.22.22.0/24(rw,async,all_squash)
# exportfs -rv
exporting 172.31.189.0/24:/nfs3/grafana/data
记得测试nfs可用性
git clone
git clone https://github.com/lijinghuatongxue/k8s_yaml.git
create ns
kubectl apply -f namespace.yaml # create ns
prometheus node yaml
先装node
kubectl apply -f node-exporter.yaml #create node
prometheus server yaml
注意 persistentVolumeReclaimPolicy 的配置，这里请灵活使用
path: /nfs3/grafana/data 这里是nfs的服务端的挂载源目录
server: 172.31.189.239这里是我的nfs的地址
kubectl apply -f prometheus.yaml # create prometheus server
grafana server yaml
这里的pv设置和prometheus server 同理
kubectl apply -f grafana.yaml # create grafana

grafana setting
添加grafana 数据源 == > 选择prometheus ==> url填这个 http://prometheus-service.ns-monitor:9090 ==> 补充模版
