Docker环境搭建Prometheus、Grafana


一、搭建基于Prometheus、Grafana监控系统

►服务器,系统版本

CentOS Linux release 7.6.1810 (Core)

二、Grafana 可视化界面示例

三、启动相关Docker服务

#yum install -y docker-io 

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

四、启动node-exporter

docker run -d -p 9100:9100 \
-v "/proc:/host/proc:ro" \
-v "/sys:/host/sys:ro" \
-v "/:/rootfs:ro" \
--net="host" \
prom/node-exporter
#查看端口占用
netstat -anpt

#URL 查看
http://192.168.91.132:9100/metrics

五、启动Prometheus并配置相关文件

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

►prometheus.yml

global:
scrape_interval: 60s
evaluation_interval: 60s

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

- job_name: linux
static_configs:
- targets: ['IP:9100']
labels:
instance: localhost

►启动

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

►查看Targets

http://IP:9090/targets

六、启动Grafana

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

►启动

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