    4. ./node_exporter

     prometheus配置node_exporter

    1. sudo mkdir /data/prometheus/data -p
    2. sudo mkdir /data/prometheus/conf -p

    编辑 /data/prometheus/conf/prometheus.yml

    修改权限

    sudo chown 1001:1001 /data/prometheus/ -R

    说明：bitnami/prometheus:2.38.0容器内用户id为1001

    启动prometheus

    docker run -d -p 9090:9090 --name prometheus -v /data/prometheus/data:/opt/bitnami/prometheus/data -v /data/prometheus/conf/prometheus.yml:/opt/bitnami/prometheus/conf/prometheus.yml bitnami/prometheus:2.38.0

    登录promethues web，查看配置 

    grafana

    docker run -d --name=grafana -p 3000:3000 --link prometheus grafana/grafana:9.1.2

    默认账号密码 admin admin，登录grafana 

    配置数据源

     选择 prometheus

     采用容器名配置连接

     保存并测试

     采用Node Exporter Full监控面板，ID：1860， 官网地址如下

    Node Exporter Full | Grafana Labs

    导入监控面板

    数据源选择刚才配置的Promethues(default)

     点击导入后，自动跳转到监控界面

    http://localhost:3000/d/rYdddlPWk/node-exporter-full?orgId=1&refresh=1m

     完成。
