一、安裝docker、docker-compose

二、安裝prometheus

1、安裝目錄準(zhǔn)備

cd /home/xxxx
mkdir -p prometheus
chmod 777 prometheus
cd prometheus
mkdir -p grafana_data prometheus_data
chmod 777 grafana_data prometheus_data

2、編寫docker-compose文件

vim docker-compose.yml

version: "3.7"
services:
  node-exporter:
    image: prom/node-exporter:latest
    container_name: "node-exporter0"
    ports:
      - "9100:9100"
    restart: always
  prometheus:
    image: prom/prometheus:latest
    container_name: "prometheus0"
    restart: always
    ports:
      - "9090:9090"
    volumes:
      - "./prometheus.yml:/etc/prometheus/prometheus.yml"
      - "./prometheus_data:/prometheus"
  grafana:
    image: grafana/grafana
    container_name: "grafana0"
    ports:
      - "3000:3000"
    restart: always
    volumes:
      - "./grafana_data:/var/lib/grafana"
      - "./grafana_log:/var/log/grafana"
      - "./grafana_data/crypto_data:/crypto_data"  # 宿主機(jī)的地址是冒號(hào)前面的，冒號(hào)后面的是容器地址，不可變，這個(gè)用來放sqlite數(shù)據(jù)庫的位置。

3、編寫prometheus.yml文件

vim prometheus.yml

global:
  scrape_interval:     15s # 默認(rèn)抓取周期
  external_labels:
    monitor: 'codelab-monitor'  
scrape_configs:
  - job_name: 'node-exporter' #服務(wù)的名稱
    scrape_interval: 5s
    metrics_path: /metrics  #獲取指標(biāo)的url
    static_configs:
      - targets: ['11.11.12.156:9100'] # 這個(gè)為監(jiān)聽指定服務(wù)服務(wù)的ip和port，需要修改為自己的ip,不能使用localhost和127.0.0.1

4、啟動(dòng)

docker-compose up -d

5、訪問

localhost:9090 #普羅米修斯的監(jiān)控頁面
localhost:3000 #grafana界面，admin/admin
