docker安装prometheus、node-exporter

1、pull 镜像

docker pull prom/prometheus

docker pull prom/node-exporter

2、启动node-exporter，注意时间同步,避免查询不到指标

docker run -d -p 9100:9100 \

-v "/proc:/host/proc" \

-v "/sys:/host/sys" \

-v "/:/rootfs" \

-v "/etc/localtime:/etc/localtime" \

--net=host \

prom/node-exporter \

--path.procfs /host/proc \

--path.sysfs /host/sys \

--collector.filesystem.ignored-mount-points "^/(sys|proc|dev|host|etc)($|/)"

3、编辑prometheus配置文件，用于后续启动prometheus指定配置文件

创建文件 /usr/local/prometheus/data/prometheus.yml

global:
scrape_interval: 60s
evaluation_interval: 60s

scrape_configs:
- job_name: prometheus
static_configs:
- targets: ['192.168.133.135:9090']
labels:
instance: prometheus

- job_name: node
static_configs:
- targets: ['192.168.133.135:9100']
labels:
instance: node

4、启动prometheus容器，注意时间同步,避免查询不到指标

注意指定配置文件 /usr/local/prometheus/data/prometheus.yml

docker run -d -p 9090:9090 \

-v /usr/local/prometheus/data/prometheus.yml:/etc/prometheus/prometheus.yml \

-v "/etc/localtime:/etc/localtime" \

--name prometheus \

--net=host \

prom/prometheus:latest

5、打开浏览器，访问node-exporter界面：http://192.168.133.135:9100/metrics
