docker 安装prometheus和grafna

一、拉取镜像

docker pull prom/prometheus

二、配置

sudo mkdir /etc/prometheus/
sudo vim /etc/prometheus/prometheus.yml

添加监控节点

# 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).

  # Attach these labels to any time series or alerts when communicating with
  # external systems (federation, remote storage, Alertmanager).
  external_labels:
      monitor: 'codelab-monitor'

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first.rules"
  # - "second.rules"

# 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: ['172.17.0.1:9090']

  - job_name: 'mysql'
    static_configs:
      - targets: ['172.17.0.1:9104']
        labels:
          instance: mysql

  - job_name: 'monitor'
    static_configs:
    metrics_path: '/actuator/prometheus'
    - targets: ['172.17.0.1:9100']
      labels:
        instance: monitor

启动prometheus

# 因为目录/data用户组和用户是jtserver，docker执行命令是root用户，先将/data/lib/prometheus给其他组权限才能执行
sudo mkdir /data/lib/prometheus
sudo chmod 767 /data/lib/prometheus

docker run -d 
  -p 9090:9090 
  --restart=always 
  --name prometheus 
  -v /data/lib/prometheus:/data/lib/prometheus 
  -v /etc/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml 
  prom/prometheus 
  --config.file=/etc/prometheus/prometheus.yml 
  --storage.tsdb.path=/data/lib/prometheus

三、拉取node-exporter

docker pull prom/node-exporter

启动

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

四、grafana

sudo apt-get install -y adduser libfontconfig1
wget https://dl.grafana.com/oss/release/grafana_6.7.2_amd64.deb
sudo dpkg -i grafana_6.7.2_amd64.deb

sudo apt-get install -y apt-transport-https
sudo apt-get install -y software-properties-common wget
wget -q -O - https://packages.grafana.com/gpg.key | sudo apt-key add -
# echo "deb https://packages.grafana.com/oss/deb stable main" | sudo tee -a /etc/apt/sources.list.d/grafana.list 
sudo add-apt-repository "deb https://packages.grafana.com/oss/deb stable main"

sudo apt-get update
sudo apt-get install grafana
sudo update-rc.d grafana-server defaults
