获取"http://localhost:9100/metrics": dial tcp [::1]:9100: connectex: 由于目标机器主动拒绝，无法建立连接

如何解决获取"http://localhost:9100/metrics": dial tcp [::1]:9100: connectex: 由于目标机器主动拒绝，无法建立连接

我已经在本地成功安装了 Prometheus。问题是我的 node 状态因错误 Get "http://localhost:9100/metrics": dial tcp [::1]:9100: connectex: No connection Could be made because the target machine actively refused it. 而关闭，但其他人没问题。

这是我在 prometheus.yml 中的配置

# my global config
global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.

# 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'

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

    static_configs:
    - targets: ['localhost:9090']
    
  - job_name: 'web'

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
    scheme: https
    static_configs:
    - targets: ['localhost:44358'] 
    
  - job_name: node

    - targets: ['localhost:9100']
