解压缩到指定目录

root@k8s-master:~/data# ls
prometheus-2.28.0-rc.0.linux-amd64.tar.gz
root@k8s-master:~/data# ls /usr/local
bin  etc  games  include  lib  man  sbin  share  src
root@k8s-master:~/data# tar xf prometheus-2.28.0-rc.0.linux-amd64.tar.gz -C /usr/local
root@k8s-master:~/data# ls /usr/local
bin  etc  games  include  lib  man  prometheus-2.28.0-rc.0.linux-amd64  sbin  share  src
##创建软链接
root@k8s-master:~/data# ln -sv /usr/local/prometheus-2.28.0-rc.0.linux-amd64 /usr/local/prometheus
'/usr/local/prometheus' -> '/usr/local/prometheus-2.28.0-rc.0.linux-amd64'
root@k8s-master:~/data# ls /usr/local/prometheus

prometheus的配置文件

root@k8s-master:~/data# cat /usr/local/prometheus/prometheus.yml 
# my global config
global:
  ##抓取数据的时间间隔，默认是1分钟
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  ##告警规则、记录规则的评估周期
  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.

##指标数据采集相关配置
scrape_configs:
  ##作业名称作为标签“job=<job_name>”添加到从此配置中抓取的任何时间序列中。
  # 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']
