Prometheus监控安装和使用

使用 Docker 安装 Prometheus

• 基础环境

  • 192.168.2.230(部署Prometheus,Grafana)
  • 192.168.2.231
  • 192.168.2.232

• 新建目录和配置文件

  mkdir -p /home/config/prometheus
  cat > prometheus.yml<<EOF
  global:
    scrape_interval: 10s
    evaluation_interval: 10s
  
  scrape_configs:
    - job_name: prometheus
      static_configs:
        - targets: ['localhost:9090']
          labels:
            instance: prometheus
  
    - job_name: linux
      static_configs:
        - targets: ['192.168.2.230:9100','192.168.2.231:9100','192.168.2.232:9100']
  
    - job_name: docker
      static_configs:
        - targets: ['192.168.2.230:9101','192.168.2.231:9101','192.168.2.232:9101']
  
    - job_name: mysql
      static_configs:
        - targets: ['192.168.2.230:9104']
  
  EOF

• 安装 Prometheus

  docker run -d \
    --name prometheus \
    -p 9090:9090 \
    -v /home/config/prometheus:/etc/prometheus \
    --restart=always \
    quay.io/prometheus/prometheus
  firewall-cmd --zone=public --add-port=9090/tcp --permanent && firewall-cmd --reload

• 安装 grafana

  docker run -d \
    --name=grafana \
    -p 3000:3000 \
    --restart=always \
    grafana/grafana
  firewall-cmd --zone=public --add-port=3000/tcp --permanent && firewall-cmd --reload

• 安装 node-exporter

  docker run -d \
    --name node-exporter \
    -p 9100:9100 \
    -v /proc:/host/proc \
    -v /sys:/host/sys \
    -v /:/rootfs \
    --restart=always \
    prom/node-exporter
  firewall-cmd --zone=public --add-port=9100/tcp --permanent && firewall-cmd --reload

• 安装 cadvisor

  docker run -d \
    --name cadvisor \
    -p 9101:8080 \
    -v /:/rootfs:ro \
    -v /var/run:/var/run:rw \
    -v /sys:/sys:ro \
    -v /var/lib/docker/:/var/lib/docker:ro \
    -v /dev/disk/:/dev/disk:ro \
    --restart=always \
    google/cadvisor
  firewall-cmd --zone=public --add-port=9101/tcp --permanent && firewall-cmd --reload

• 安装 mysql-exporter

  • 新增用户

    CREATE USER 'exporter'@'%' IDENTIFIED BY '********';
    GRANT PROCESS, REPLICATION CLIENT ON *.* TO 'exporter'@'%';
    GRANT SELECT ON `performance\_schema`.* TO 'exporter'@'%';

  • 添加监控容器

    docker run -d \
      --name mysql-exporter \
      -p 9104:9104 \
      -e DATA_SOURCE_NAME="user:password@(url:port)/database" \
      --restart=always \
      prom/mysqld-exporter
    firewall-cmd --zone=public --add-port=9104/tcp --permanent && firewall-cmd --reload
