docker-compose部署Prometheus+grafana

1.docker和docker-compose请自行下载安装

2.docker-compose.-prometheus.yml文件

持久化目录需要给777权限，否则容器启动失败

vim docker-compose-prometheus.yml

version: "3.7"
services:
  node-exporter:
    image: prom/node-exporter:latest
    network_mode: "host"
#    ports:
#      - "9100:9100"
    restart: always
  prometheus:
    image: prom/prometheus:latest
    network_mode: "host"
    restart: always
#    ports:
#      - "9090:9090"
    volumes:
      - "./prometheus.yml:/etc/prometheus/prometheus.yml"
      - "./prometheus_data:/prometheus"
  grafana:
    image: grafana/grafana
    network_mode: "host"
#    ports:
#      - "3000:3000"
    restart: always
    volumes:
      - "./grafana_data:/var/lib/grafana"

prometheus主机需要部署以上容器，其他被监控主机只需要部署node-exporter

3.prometheus配置文件

vim prometheus.yml

global:

  scrape_interval:     60s

  evaluation_interval: 60s

scrape_configs:

  - job_name: prometheus

    static_configs:

      - targets: ['10.3.192.37:9090']

        labels:

          instance: prometheus

  - job_name: bank

    static_configs:

      - targets: ['10.3.192.37:9100']

        labels:

          instance: 10.3.192.37

  - job_name: client

    static_configs:

      - targets: ['10.3.192.38:9100']

        labels:

          instance: 10.3.192.38

4.docker-compose启动

./docker-compose -f docker-compose-prometheus.yml up -d         # 挂载目录给权限，不然会启动失败

5.访问主机的9090端口可以查到Prometheus监控到的数据，访问3000端口是grafana的界面，

   账密admin/admin

6.配置监控，点击齿轮，选择Data Sources

7.点击Add data source

 

 8.填写prometheus地址 ip+端口或者主机名+端口（需要配置hosts）

9.点击save&test

10.点击+号，选择import

11.输入模板号9276，点击load。    8919

11.导入模板完成
