概述

本文记录，使用docker在Linux机器，安装Prometheus与Grafana。

正文

• 1.新建prometheus.yml文件，内容如下

global:
  scrape_interval:     15s # By default, scrape targets every 15 seconds.

  # Attach these labels to any time series or alerts when communicating with
  # external systems (federation, remote storage, Alertmanager).
  external_labels:
    monitor: 'codelab-monitor'

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # Override the global default and scrape targets from this job every 5 seconds.
    scrape_interval: 5s

    static_configs:
            - targets: ['localhost:9090','192.168.31.162:9100']

• 2.启动prometheus容器

docker run --name=prometheus -d -p 9090:9090 
-v /data/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml 
-v /data/prometheus/rules.yml:/etc/prometheus/rules.yml prom/prometheus 
--config.file=/etc/prometheus/prometheus.yml 
--web.enable-lifecycle

//重载配置文件命令
curl -X POST http://localhost:9090/-/reload

• 3.收集Linux信息

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

• 4.启动Grafana

 docker run -d -p 3001:3000 --name grafana grafana/grafana

• 5.配置模版信息
