[prometheus系列] 二进制方式部署prometheus server

添加运行promtheus的用户

useradd -u 8001 -s /sbin/nologin -M prometheus
useradd -u 8002 -s /sbin/nologin -M node_exporter

创建配置，数据相关目录

mkdir /etc/prometheus
mkdir /data/prometheus
chown prometheus:prometheus /etc/prometheus/
chown prometheus:prometheus /data/prometheus/

下载软件包

wget https://github.com/prometheus/prometheus/releases/download/v2.1.0/prometheus-2.1.0.linux-amd64.tar.gz
tar -xf prometheus-2.1.0.linux-amd64.tar.gz 

部署

# 二进制程序部署
cp prometheus-2.1.0.linux-amd64/promtool /usr/local/bin/
cp prometheus-2.1.0.linux-amd64/prometheus /usr/local/bin/
chown  prometheus.prometheus /usr/local/bin/prom*

# 配置部署
cp prometheus-2.1.0.linux-amd64/prometheus.yml /etc/prometheus/
cp -r prometheus-2.1.0.linux-amd64/consoles/ /etc/prometheus/
cp -r prometheus-2.1.0.linux-amd64/console_libraries/ /etc/prometheus/

chown -R prometheus:prometheus /etc/prometheus/

示例而已

cat /etc/prometheus/prometheus.yml

global:
  scrape_interval:     90s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 90s # Evaluate rules every 15 seconds. The default is every 1 minute.
  scrape_timeout: 15s      # scrape_timeout is set to the global default (10s).
  external_labels:
      monitor: 'lovego-monitor'

rule_files:
  - "/etc/prometheus/rules/*.rules"

scrape_configs:
  - job_name: 'prometheus-server'
    scrape_interval: 60s
    scrape_timeout: 10s
    static_configs:
      - targets: ['10.10.16.7:9090']
        labels:
          instance: prometheus_server

  - job_name: 'node_exporter_prometheus_16_7'
    scrape_interval: 60s
    static_configs:
      - targets: ['10.10.16.7:9093']
        labels:
          instance: node_16_7
          group: common-server
alerting:
  alertmanagers: 
  - scheme: http
    static_configs:
    - targets: ['10.10.16.7:9095']
