缘由

之前是jar 安装到服务器,但是服务器重启后,没有自启动,而且很多都是docker维护,有平台方便重启,

最后还是决定docker 安装prometheus

安装

docker run -itd --name=prometheus --restart=always -p 9090:9090 prom/prometheus

容器创建成功后，即可通过浏览器访问 http: / /{ip}:9090  来进行验证

配置

复制docker内配置文件出来

docker cp prometheus:/etc/prometheus/prometheus.yml $PWD

[root@Docker ~]# 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
    static_configs:
    - targets: ['192.168.1.1:9100']         #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)
      labels:
        instance: localhost

修改后 复制回去

docker cp $PWD/prometheus.yml prometheus:/etc/prometheus/prometheus.yml

 最后重启prometheus
