[小白系列]Ubuntu安装教程-安装prometheus和Grafana

Docker安装prometheus

拉取镜像

docker pull prom/prometheus

配置文件prometheus.yml

在/data/prometheus/建立prometheus.yml配置文件。（/data/prometheus/可根据自己需要调整）

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']

启动服务

（/data/prometheus 改为你的目录）

docker run -d --name prometheus --restart always -p 9090:9090 -v /data/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml   prom/prometheus

启动时加上--web.enable-lifecycle启用远程热加载配置文件
调用指令是curl -X POST http://localhost:9090/-/reload 

访问

http://IP:9090/query

IP改为你服务器的IP地址

Docker安装Grafana

拉取镜像

docker pull grafana/grafana-oss

启动

docker run -d --name=grafana --restart always  -p 3000:3000 grafana/grafana-oss

访问

http://IP:3000

默认用户名密码 admin   admin  登录提示修改密码

配置DataSource

注意添加Prometheus时可以顺便添加上Dashboards

点击import

Docker安装node-exporter

安装

docker pull prom/node-exporter
docker run -d --name node_exporter --restart always -p 9100:9100 prom/node-exporter

下面不知道干嘛的，暂时记录

docker run -d --name node_exporter --restart always -p 9100:9100  -v "/proc:/host/proc:ro"  -v "/sys:/host/sys:ro"  -v "/:/rootfs:ro"  prom/node-exporter

验证

要验证node_exporter是否成功运行，可以访问主机的9100端口，通常可以通过以下URL在浏览器中查看指标数据（假设你的Docker宿主机IP为HOST_IP）：
http://HOST_IP:9100 或者 http://HOST_IP:9100/metrics

prometheus配置

在prometheus.yml中再增加一个job

 - job_name: 'node_exporter'
    static_configs:
      - targets: ['192.168.60.33:9100']

Grafana配置Node-exporter的Dashboards

dashboars地址： Grafana dashboards | Grafana Labs

找到node exporter full

选择 Copy ID to clipboard

登录grafana

填写ID，然后点击[Load]

注意选择一个配置的promethus数据源
