1、promethues安装

docker pull bitnami/prometheus:2.48.1

配置文件下载：https://prometheus.io/download/

如果需要授权相关文件夹权限，可以参考下面的命令

chmod -R 777 /home/docker_data/monitor/prometheus/data
chmod -R 777 /home/docker_data/monitor/prometheus/rules
chmod -R 777 /home/docker_data/monitor/prometheus/conf

先去掉挂在目录的data,rules,config

docker run -itd --name prometheus  --restart=always   -p 9090:9090 -v /etc/localtime:/etc/localtime bitnami/prometheus:2.48.1

启动后会报错：
查看日志：docker logs prometheus
err="open /opt/bitnami/prometheus/data/queries.active: permission den

拷贝配置文件（也可以直接下载配置文件prometheus.yml）
docker cp prometheus:/opt/bitnami/prometheus/conf/prometheus.yml /home/docker_data/monitor/prometheus/conf

添加挂载目录启动

docker run -itd --name prometheus  --restart=always   -p 9090:9090 -v /etc/localtime:/etc/localtime -v /home/docker_data/monitor/prometheus/data:/opt/bitnami/prometheus/data  -v /home/docker_data/monitor/prometheus/conf:/opt/bitnami/prometheus/conf -v /home/docker_data/monitor/prometheus/rules:/opt/bitnami/prometheus/rules bitnami/prometheus:2.48.1

2、node-exporter安装

docker pull bitnami/node-exporter:1.7.0docker run -itd  --name node-exporter  --restart=always   -p 9100:9100  -v /etc/localtime:/etc/localtime -v /home/docker_data/monitor/node-exporter/proc:/host/proc:ro  -v /home/docker_data/monitor/node-exporter/sys:/host/sys:ro -v /home/docker_data/monitor/node-exporter/:/rootfs:ro  bitnami/node-exporter:1.7.0

3、grafana安装

docker pull grafana/grafana:10.1.6docker run -itd --name grafana  --restart=always -p 3000:3000  -v /etc/localtime:/etc/localtime -v /home/docker_data/monitor/grafana:/var/lib/grafana grafana/grafana:10.1.6

初始化密码：admin/admin. 修改后:lwd123456
访问地址：http://192.168.1.231:3000/
admin/lwd123456

如果admin密码忘记了，那么可以执行：grafana-cli admin reset-admin-password admin123，修改密码

4、配置promethues监控node节点

vim prometheus.yml
在Prometheus配置文件按以下内容修改：

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: ['localhost:9090']labels:instance: prometheus- job_name: linux-231static_configs:- targets: ['192.168.1.231:9100']                   #被监控端的IP地址和端口号(有多个被监控端可用 逗号 隔开)- job_name: linux-230static_configs:- targets: ['192.168.1.230:9100']

5、grafana操作

官网：https://grafana.com/grafana/dashboards
模版下载：https://grafana.com/grafana/dashboards/12884-1-node-exporter-for-prometheus-dashboard-cn-v20200628/

在grafana仪表盘中导入12884模块，如果没有数据，可能是版本或者其他原因，尝试升级模块
