基于 docker 搭建 prometheus 和 grafan

全文转载自：基于Docker搭建Prometheus+Grafana

拉取镜像

# docker pull prom/prometheus
# docker pull grafana/grafana
# docker pull prom/node-exporter

启动node exporter

# docker run -d -p 9100:9100 \
  -v "/proc:/host/proc:ro" \
  -v "/sys:/host/sys:ro" \
  -v "/:/rootfs:ro" \
  prom/node-exporter

打开: http://192.168.48.20:9100/metrics node exporter 采集到的数据：

启动prometheus

准备配置文件

# mkdir /opt/prometheus && cd /opt/prometheus/
# vim prometheus.yml

编辑内容如下：

global:
  scrape_interval:     60s
  evaluation_interval: 60s
 
scrape_configs:
  - job_name: prometheus
    static_configs:
      - targets: ['localhost:9090']
        labels:
          instance: prometheus
 
  - job_name: linux
    static_configs:
      - targets: ['192.168.48.20:9100']
        labels:
          instance: localhost

启动prometheus

# docker run  -d \
  -p 9090:9090 \
  -v /opt/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml  \
  prom/prometheus

打开: http://192.168.48.20:9090/graph

启动grafana

空文件夹grafana-storage，用来存储数据，因为grafana用户会在这个目录写入文件，直接设置777，比较简单粗暴！

# mkdir /opt/grafana-storage && chmod 777 -R /opt/grafana-storage

启动granafa

# docker run -d \
  -p 3000:3000 \
  --name=grafana \
  -v /opt/grafana-storage:/var/lib/grafana \
  grafana/grafana

打开：http://192.168.48.20:3000 初始用户和密码都是admin，配置pprometheus作为数据源
