Prometheus 支持多种多样的安装方式， 如：

  • 自行编译源码
  • 预编译好的二进制包
  • 基于docker的镜像
  • ansible 安装等等

本文主要使用预编译好的二进制包进行安装， 采用的版本为 v2.22.2

1. 环境准备

  1. 安装环境： CentOS 7
  2. 下载 Prometheus 
    1. # 下载 Prometheus 预编译好的二进制压缩包
    2. wget https://github.com/prometheus/prometheus/releases/download/v2.22.2/prometheus-2.22.2.linux-amd64.tar.gz
    3. # 解压压缩包
    4. tar -zxvf prometheus-2.22.2.linux-amd64.tar.gz
    5. # 重命名为 prometheus
    6. mv prometheus-2.22.2.linux-amd64 prometheus
    7. # 进入目录
    8. cd prometheus

    2. 配置 prometheus.yml

    1. # 全局配置
    2. global:
    3. scrape_interval:     15s # 每间隔 15 秒抓取一次指标， 默认是 1 分钟
    4. evaluation_interval: 15s # 每间隔 15 秒根据规则计算一次， 默认是 1 分钟
    5. scrape_timeout:      15s # 抓取节点指标超时时间
    6. # 告警管理配置
    7. alerting:
    8. alertmanagers:
    9. - static_configs:
    10.  - targets:
    11.    # - alertmanager:9093
    12. # 初始化时加载一次规则，根据 evaluation_interval ，每间隔一段时间根据规则执行一次计算
    13. rule_files:
    14. # - "first_rules.yml"
    15. # - "second_rules.yml"
    16. # 各个需要抓取 metrics 的端点
    17. # metrics_path 不指定时， 默认是 /metrics
    18. scrape_configs:
    19. # 服务器抓取 metrics 节点
    20. - job_name: 'node'
    21.  scrape_interval: 5s
