二進制安裝Prometheus

服務器列表：node

服務器名稱 操做系統 IP地址 服務
test03 Ubuntu 16.04.4 192.168.1.58 Prometheus, Alertmanager,grafana
test02 Ubuntu 16.04.4 192.168.1.57 Node_exporter

一、安裝prometheus

  • Prometheus官網下載地址：https://prometheus.io/download/
    二進制安裝Prometheuslinux

  • 下載prometheusgit

    root@test03:~# wget https://github.com/prometheus/prometheus/releases/download/v2.11.0/prometheus-2.11.0.linux-amd64.tar.gz

  • 解壓prometheus
    root@test03:~# tar xf prometheus-2.11.0.linux-amd64.tar.gzgithub

  • 移動到/usr/local/prometheus目錄
    root@test03:~# mv prometheus-2.11.0.linux-amd64 /usr/local/prometheusdocker

  • 設置prometheus後臺服務啓動
root@test03:~# cat  /lib/systemd/system/prometheus.service 
[Unit]
Description=https://prometheus.io

[Service]
ExecStart=/usr/local/prometheus/prometheus --config.file="/usr/local/prometheus/prometheus.yml"

[Install]
WantedBy=multi-user.target

  • 建立prometheus服務服務器

    root@test03:~# systemctl enable prometheus.service
Created symlink from /etc/systemd/system/multi-user.target.wants/prometheus.service to /lib/systemd/system/prometheus.service.

  • 啓動prometheus服務
    root@test03:~# systemctl start prometheus.servicetcp

  • 查看promethues服務狀態ide

    root@test03:~# systemctl status prometheus.service 
● prometheus.service - https://prometheus.io
Loaded: loaded (/lib/systemd/system/prometheus.service; enabled; vendor preset: enabled)
Active: active (running) since Wed 2019-07-10 11:10:45 CST; 4s ago
Main PID: 818 (prometheus)

二、安裝Grafana

  • docker 安裝測試

    root@test03:~# docker run -d -p 3000:3000 grafana/grafana
root@test03:~# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                    NAMES
a6ff7bd88b42        grafana/grafana     "/run.sh"           43 seconds ago      Up 41 seconds       0.0.0.0:3000->3000/tcp   peaceful_brattain

  • 訪問：http://192.168.1.58:3000
    登陸gafana界面：
    默認帳號是：admin
    默認密碼是：admin
    第一次登陸後，提示從新設置密碼

三、監控Linux服務器

  • 安裝node_exporter並啓動
root@test02:~# wget https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz
root@test02:~# tar xf node_exporter-0.18.1.linux-amd64.tar.gz
root@test02:~# mv node_exporter-0.18.1.linux-amd64 /usr/local/node_exporter
root@test02:~# cd /usr/local/node_exporter
root@test02:/usr/local/node_exporter# cat /lib/systemd/system/node_exporter.service
[Unit]
Description=https://prometheus.io/docs/guides/node-exporter/

[Service]

[Install]
WantedBy=multi-user.target

root@test02:/usr/local/node_exporter# systemctl enable node_exporter.service

cat /usr/local/prometheus/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']
  - job_name: 'host'
    file_sd_configs:
      - files: ['/usr/local/prometheus/sd_config/host.yml']
        refresh_interval: 5s
  • 建立host.yaml文件
root@test03:/usr/local/prometheus/sd_config# cat /usr/local/prometheus/sd_config/host.yml 
- targets:
  - 192.168.1.57:9100

  • 重載配置文件

    prometheus_id=`ps -ef |grep prometheus.yml|grep -v grep|awk '{print $2}'`
kill -hup $prometheus_id
  • 查看Targets host，host組，已存在192.168.1.57被監控端
