使用docker compose安装

方便拓展, 配置信息都放在在 /docker/prometheus 目录下

1.目录结构如下

.
├── conf
│   └── prometheus.yml
├── grafana_data
├── prometheus_data
└── prometheus_grafana.yaml

2.创建目录文件

mkdir /docker/prometheus && chmod 777 /docker/prometheus

cd /docker/prometheus && mkdir grafana_data prometheus_data && chmod 777 grafana_data prometheus_data

2.1 创建docker compose文件

touch prometheus_grafana.yaml

写入

version: "3.7"

networks:
  prometheus:

services:
  node-exporter:
    image: prom/node-exporter:latest
    container_name: "node-exporter0"
    ports:
      - "9101:9100"  #按需修改, 宿主机端口: 容器端口
    restart: always
    networks:
      - prometheus
  prometheus:
    image: prom/prometheus:latest
    container_name: "prometheus0"
    restart: always
    ports:
      - "9090:9090"
    volumes:
      - "./conf/prometheus.yml:/etc/prometheus/prometheus.yml"
      - "./prometheus_data:/prometheus"
    networks:
      - prometheus
  grafana:
    image: grafana/grafana:latest
    container_name: "grafana0"
    ports:
      - "3000:3000"
    restart: always
    volumes:
      - "./grafana_data:/var/lib/grafana"
    networks:
      - prometheus

2.2在/docker/prometheus 目录下

mkdir conf && touch conf/prometheus.yml

vim mkdir conf && touch conf/prometheus.yml

写入配置, 注意修改中文注释位置

global:
  scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
    - static_configs:
        - targets:
          # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
# - "first_rules.yml"
# - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: [ 'localhost:9090' ]

  - job_name: test            #按需修改, 任务名
    static_configs:
    - targets: ['ip:9101']      #端口, 上面prometheus_grafana的node-exporter的port设置是9101
      labels:
        instance: ins-1         #实例名

启动

docker-compose -f prometheus_grafana.yaml up -d

3.prometheus信息

访问http://ip:9090/targets

能看到node-exporter的推送信息

4.登录grafana

访问http://ip:3000

账号密码默认admin

4.1配置数据源

在connection–> datasource–> Add data source选择 Prometheus

输入Prometheus地址, 测试成功

4.2. 配置dashboard

回到datasource页面, Build a dashboard–>Import a dashboard–>输入12633选择一个面板, 导入刚刚Prometheus

就能看到监控面板了
