下载镜像包

sudo docker pull prom/node-exporter 
sudo docker pull prom/prometheus 
sudo docker pull grafana/grafana

启动node-exporter

sudo docker run -d -p 9100:9100   -v "/proc:/host/proc:ro"  -v "/sys:/host/sys:ro"   -v "/:/rootfs:ro" prom/node-exporter

启动prometheus

新建目录 prometheus，编辑配置文件prometheus.yml

sudo mkdir /opt/prometheus 
cd /opt/prometheus/ 
sudo vim prometheus.yml 

内容如下:

global:
  scrape_interval:     60s
  evaluation_interval: 60s
scrape_configs:
  - job_name: prometheus
    static_configs:
      - targets: ['localhost:9090']
        labels:
          instance: prometheus
  - job_name: linux
    static_configs:
      - targets: ['127.0.0.1:9100']
        labels:
          instance: localhost

启动prometheus

sudo docker run  -d \
  -p 9090:9090 \
  -v /opt/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml  \
  prom/prometheus

如果grafana启动遇到问题： grafana报错Panel plugin not found grafana-piechart-panel

启动grafana

新建空文件夹grafana-storage，用来存储数据

mkdir /opt/grafana-storage

设置权限

chmod 777 -R /opt/grafana-storage

启动grafana（如果和已有的端口冲突改一下端口）

sudo docker run -d \
  -p 3000:3000 \
  --name=grafana \
  -v /opt/grafana-storage:/var/lib/grafana \
  grafana/grafana
