配置节点

global:
  scrape_interval: 15s

scrape_configs:
  # 静态写法——直接写死 IP
  - job_name: 'node-static'
    static_configs:
      - targets:
        - '192.168.1.11:9110'   # 第 1 台被监控机
        - '192.168.1.12:9110'   # 第 2 台被监控机
        - '192.168.1.13:9110'   # 第 3 台被监控机

  # 文件发现写法——把 IP 写到单独 JSON/YAML 文件，便于自动扩缩
  - job_name: 'node-file'
    file_sd_configs:
      - files:
        - '/etc/prometheus/targets/nodes.yml'

/etc/prometheus/targets/nodes.yml 格式示例：

#方式1：直接加目标地址即可
wangj1028@Mac etc % more /opt/homebrew/etc/nodes.yml 
- targets: ['106.14.95.21:9100']
- targets: ['111.229.194.1:9100']

#方式2：还可以添加相关的标签
- targets: ['192.168.1.21:9110']
  labels:
    env: prod
- targets: ['192.168.1.22:9110']
  labels:
    env: test

添加其它节点数据

vim prometheus.yml

global:
  scrape_interval: 15s

scrape_configs:
  - job_name: 'node_exporter'
    static_configs:
      - targets: ['192.168.70.128:9100']

mac 安装

通过 Homebrew 安装

# 安装 Prometheus
brew install prometheus

# 启动 Prometheus 服务，并设置为开机自启
brew services start prometheus

验证安装

启动后，打开浏览器访问 http://localhost:9090。如果能看到 Prometheus 的 Web 界面，就说明安装和启动都成功了

停止服务：brew services stop prometheus

重启服务：brew services restart prometheus

升级 Prometheus：brew upgrade prometheus (升级后通常需要重启服务)

配置文件位置：Prometheus 的主配置文件 prometheus.yml 位于：

Intel 芯片 Mac：/usr/local/etc/prometheus.yml

Apple Silicon 芯片 Mac：/opt/homebrew/etc/prometheus.yml
