一、Prometheus的安装和运行

docker_2">1、使用docker拉取镜像

sudo docker pull prom/prometheus

prometheusyml_8">2、创建prometheus.yml文件

vim /etc/prometheus/prometheus.yml

编写yml文件

global:
  scrape_interval: 15s
  evaluation_interval: 15s
scrape_configs:
  - job_name: 'prometheus'
    static_configs:
    - targets: ['localhost:9090']

3、启动容器

sudo docker run -d --name prometheus -p 9090:9090 -v /home/ubuntu/promdata/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus

4、查看启动是否成功

在这里插入图片描述

5、记录安装过程中出现的错误

错误原因：yaml格式不正确，yaml有自己严格的格式要求

ubuntu@VM-24-12-ubuntu:~/promdata$ sudo docker logs prometheus
ts=2023-04-04T04:14:49.067Z caller=main.go:468 level=error msg="Error loading config (--config.file=/etc/prometheus/prometheus.yml)" file=/etc/prometheus/prometheus.yml err="parsing YAML file /etc/prometheus/prometheus.yml: yaml: line 5: did not find expected '-' indicator"

二、Grafana的安装和运行

docker_39">1、使用docker拉取镜像

docker pull grafana/grafana

grafana_45">2、创建grafana

mkdir /home/ubuntu/grafana/
chmod 777 /home/ubuntu/grafana/

grafana_51">3、运行grafana

sudo docker run -d -p 3000:3000 --name=grafana -v /home/ubuntu/grafana:/var/lib/grafana grafana/grafana

ubuntu@VM-24-12-ubuntu:~$ sudo docker ps
