grafana和prometheus系列一：通过docker-c

一、安装docker、docker-compose

二、安装prometheus

1、安装目录准备

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

2、编写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"  # 宿主机的地址是冒号前面的，冒号后面的是容器地址，不可变，这个用来放sqlite数据库的位置。

3、编写prometheus.yml文件

vim prometheus.yml

global:
  scrape_interval:     15s # 默认抓取周期
  external_labels:
    monitor: 'codelab-monitor'  
scrape_configs:
  - job_name: 'node-exporter' #服务的名称
    scrape_interval: 5s
    metrics_path: /metrics  #获取指标的url
    static_configs:
      - targets: ['11.11.12.156:9100'] # 这个为监听指定服务服务的ip和port，需要修改为自己的ip,不能使用localhost和127.0.0.1

4、启动

docker-compose up -d

5、访问

localhost:9090 #普罗米修斯的监控页面
localhost:3000 #grafana界面，admin/admin
