快速安装（暂不可用）

Prometheus安装可使用一键安装脚本https://gitee.com/lushanyanyv/prometheus

Grafana安装请参照下文

服务器监控只需要一个grafana即可，每台服务安装Prometheus，使用脚本更便捷！

国内

curl -sL https://gitee.com/li-chen-xing/prometheus/raw/master/prometheus-setup.sh | sed 's/\r$//' | bash

国外

curl -sL https://gitee.com/li-chen-xing/prometheus/raw/master/prometheus-setup-abroad.sh | sed 's/\r$//' | bash

准备

关闭防火墙

systemctl stop firewalld
systemctl disable firewalld

关闭selinux

sed -i 's/enforcing/disabled/' /etc/selinux/config  # 永久
setenforce 0  # 临时
sestatus   #查询Selinux状态

下载软件包CentOS

进阶

修改 prometheus.yml

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

  # 添加 PushGateway 监控配置
  - job_name: 'pushgateway'
    static_configs:
      - targets: ['localhost:9091']
        labels:
          instance: pushgateway

  # 添加 Node Exporter 监控配置
  - job_name: 'node exporter'
    static_configs:
      - targets: ['localhost:9100']

可选

  # 添加 Node Exporter 监控配置
  - job_name: 'node exporter'
    static_configs:
      - targets: ['localhost1:9100', 'localhost2:9100', 'localhost3:9100']

中文注释

# 我的全局配置
global:
  scrape_interval: 15s  # 设置每隔15秒抓取一次数据。默认为每分钟一次。

  # - "second_rules.yml"

# 抓取配置，包含一个用于抓取的端点：
# 这里是 Prometheus 本身。
scrape_configs:
  # 作业名称将作为标签 `job=<job_name>` 添加到从此配置中抓取的任何时间序列上。
