启动prometheus

新建目录prometheus，编辑配置文件prometheus.yml

mkdir /opt/prometheus
cd /opt/prometheus/
vim prometheus.yml

global:
  scrape_interval:     60s
  evaluation_interval: 60s
 
scrape_configs:
  - job_name: prometheus
    static_configs:
      - targets: ['localhost:9090']
        labels:
          instance: prometheus
 
  - job_name: linux
    static_configs:
      - targets: ['192.168.0.132:9100']
        labels:
          instance: localhost

注意：修改IP地址，这里的192.168.0.132就是本机地址
