docker部署Prometheus+Grafana

一、安装Prometheus

# 创建目录
mkdir -p /data/prometheus/prometheus-data
cd /data/prometheus/

# 拉取prometheus镜像
docker pull prom/prometheus

# 初次启动cp配置文件
docker run -d --name prometheus prom/prometheus

# 拷贝配置文件到 /data/prometheus/目录
docker cp prometheus:/etc/prometheus/prometheus.yml .

# 配置权限
chmod -R 775 /data/prometheus

# 启动服务
docker run --name prometheus -p 9090:9090 -v /data/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml -v /data/prometheus/prometheus-data:/prometheus -d prom/prometheus

二、配置node-exporter监控主机、google/cadvisor监控docker

1、主机监控node-exporter

docker run -d -p 9100:9100 -v /proc:/host/proc -v /sys:/host/sys -v /:/rootfs prom/node-exporter --path.procfs /host/proc --path.sysfs /host/sys --collector.filesystem.ignored-mount-points "^/(sys|proc|dev|host|etc)($|/)"

2、docker监控

docker run -v /:/rootfs:ro -v /var/run:/var/run/:rw -v /sys:/sys:ro -v /var/lib/docker:/var/lib/docker:ro -p 8080:8080 --detach=true --name=cadvisor google/cadvisor

3、配置prometheus监控（就是第一步配置的服务）

# 修改配置文件
cd /data/prometheus
vim 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:

rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

scrape_configs:
  - job_name: "prometheus"

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
      - targets: ["localhost:9090"]


  - job_name: '被监控主机主机名'
    static_configs:
      - targets: ["主机IP:8080","主机IP:9100"]

# 配置文件保存后重启prometheus容器重载配置
docker restart prometheus

三、安装Grafana

# 拉取镜像
docker pull grafana/grafana

# 启动grafana
docker run --name grafana -d -p 3000:3000 grafana/grafana

访问地址：主机IP地址加3000端口

默认用户名密码：admin/admin

输入prometheus访问地址端口连接，然后点击Save & test 按钮

导入主机监控模板，官方有很多监控模板，我这里选择了ID为8919的模板

可以自定义名称，选择prometheus，点击导入

效果图

导入docker监控模板，导入方式相同，模板ID：11600
