# 参数解释

1.指定Prometheus配置文件的路径
--config.file=/etc/prometheus/prometheus.yml

2.指定Prometheus时间序列数据库的存储路径
--storage.tsdb.path=/var/lib/prometheus

3.指定Prometheus控制台模板的路径，控制台模板用于呈现和可视化指标数据
--web.console.templates=/etc/prometheus/consoles

4.指定Prometheus控制台库的路径，控制台库包含用于控制台模板的共享库文件。
--web.console.libraries=/etc/prometheus/console_libraries:

5.指定Prometheus Web界面的监听地址为0.0.0.0:9090
--web.listen-address=0.0.0.0:9090

• 配置prometheus.yml

global:
  scrape_interval:     15s # By default, scrape targets every 15 seconds.

  # Attach these labels to any time series or alerts when communicating with
  # external systems (federation, remote storage, Alertmanager).
  external_labels:
    monitor: 'codelab-monitor'

# 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'
    scrape_interval: 5s
    static_configs:
      - targets: ['localhost:9090']

# 参数解释

global：全局配置
scrape_interval：设置prometheus守护进程拉取agent信息时间间隔
evaluation_interval：设置根据后面rule_files字段定义的规则计算的时间间隔

alerting：告警配置
用于配置告警信息，需要通过alertmanagers插件实现，这里暂时未配置

rule_files：规则配置
主要用于触发告警，这里也暂未配置

scrape_configs：抓取目标机器配置
job_name：标识这条记录，也就是这个配置内的记录都会添加上该字段
targets：设置目标机地址

• 重新载入daemon-raload

systemctl daemon-reload

• 启动服务&设置开机自启

systemctl start prometheus.service
systemctl enable prometheus.service

• 查看运行状态

systemctl status prometheus.service
