下载解压后，直接运行 ./prometheus即可。

默认开启的端口是9090。

安装grafana

docker pull docker.io/grafana/grafana
docker run -d --name=grafana -p 3000:3000 grafana/grafana

然后新增一个prometheus的数据源，选择 8919模版。

https://grafana.com/grafana/dashboards/8919

默认开启的端口是3000

安装node_exporter

https://github.com/prometheus/node_exporter/releases/download/v1.1.2/node_exporter-1.1.2.linux-amd64.tar.gz

下载地址解压，运行即可。

默认开启的端口是9100。

需要手动在 prometheus server端配置上节点。

scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
    - targets: ['localhost:9090']
  - job_name: 'nodes'
    static_configs:
    - targets:
      - "106.12.xxx.xxx:9100"
      - "106.15.xxx.xxx:9100"
      - "121.42.xxx.xxx:9100"
      - "122.152.xxx.xxx:9100"

文件的服务发现

上面的配置都是手动新增，我们利用新增配置文件，让server自定载入，服务发现即可。

# my global config
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.


# 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'
    file_sd_configs:
    - files:                                                #指定加载的文件列表
        - targets/prometheus-*.yaml     # 文件加载支持glob通配符
        refresh_interval: 2m                    # 每隔2分钟重新加载一次文件中定义的targets，默认5m
        
  - job_name: 'nodes'
        file_sd_configs:
        - files:
            - targets/nodes-*.yaml
            refresh_interval: 2m

targets/nodes-linux.yaml

- targets:
  - "106.12.xxx.xxx:9100"
  - "106.15.xxx.xxx:9100"
  - "121.42.xxx.xxx:9100"
  - "122.152.xxx.xxx:9100"
  labels:
    app:node_exporter

targets/prometheus-server.yaml

- targets:
  - "localhost:9090"
  labels:
    app:prometheus

mysql监控

先在grafana里添加mysql的数据源。

将my2.sql文件导入数据库，https://github.com/john1337/my2Collector

用 https://grafana.com/grafana/dashboards/7991 这个模版，最终展示即可。
