容器化部署prometheus

    1、安装docker
    

[root@prometheus ~]# docker version

    2、运行prometheus容器
    

//拉取镜像
[root@prometheus ~]# docker pull prom/prometheus

//在/opt目录下提供prometheus的默认配置文件
[root@prometheus ~]# ls /opt/

//运行容器

## 将本地提供的配置文件映射到容器,ro 容器内只读
[root@prometheus ~]# docker run --name prometheus -d --restart always -p 9090:9090 -v /opt/prometheus.yml:/etc/prometheus/prometheus.yml:ro prom/prometheus:latest

    使用ip+9090/targets访问prometheus默认网页
    
    部署node_exporter

    

//下载安装包
[root@node-exporter ~]# wget https://github.com/prometheus/node_exporter/releases/download/v1.3.0/node_exporter-1.3.0.linux-amd64.tar.gz
[root@node-exporter ~]# ls
anaconda-ks.cfg  node_exporter-1.3.0.linux-amd64.tar.gz

//解压
[root@node-exporter ~]# tar xf node_exporter-1.3.0.linux-amd64.tar.gz -C /usr/local/
[root@node-exporter ~]# mv /usr/local/node_exporter-1.3.0.linux-amd64/ /usr/local/node_exporter
[root@node-exporter ~]# ls /usr/local/
bin  etc  games  include  lib  lib64  libexec  node_exporter  sbin  share  src

//编写service文件,启动并开机自启

## node-exporter部署成功就可以在Prometheus主机上添加节点进行监控


    添加节点到prometheus中

    修改本地prometheus.yml文件
    

//修改配置文件
[root@prometheus ~]# tail -8 /opt/prometheus.yml 
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"
    static_configs:
      - targets: ["localhost:9090"]
  - job_name: "centos"			//指定一个工作名称
    static_configs:
      - targets: ["192.168.237.131:9100"]				//指定node-exporter节点的IP和端口号
## 如果有多个节点
  - job_name: "centos"	
    static_configs:
      - targets: 
        - "192.168.237.131:9100"
        - "192.168.237.132:9100"
        - "192.168.237.133:9100"


//重启容器,重新读取配置文件
[root@prometheus ~]# docker restart prometheus
prometheus
[root@prometheus ~]# docker ps
CONTAINER ID   IMAGE                             COMMAND                  CREATED          STATUS                    PORTS                                       NAMES

    访问prometheus默认网页
    成功添加节点
    
    部署grafana画图工具

    

//拉取grafan/grafan官方镜像
