# 一、概述 #

理论知识就不多介绍了，参考链接：

[https://www.cnblogs.com/xiao987334176/p/9930517.html][https_www.cnblogs.com_xiao987334176_p_9930517.html]

本文使用2台服务器，来搭建。

## 环境 ##

<table> 
 <tbody> 
  <tr> 
   <td>操作系统</td> 
   <td>docker版本</td> 
   <td>ip</td> 
   <td>容器</td> 
  </tr> 
  <tr> 
   <td>centos 7.4</td> 
   <td>18.09.2</td> 
   <td>192.168.10.104</td> 
   <td>Prometheus+Grafana+node-exporter</td> 
  </tr> 
  <tr> 
   <td>centos 7.4</td> 
   <td>18.09.2</td> 
   <td>192.168.10.20</td> 
   <td>node-exporter</td> 
  </tr> 
 </tbody> 
</table>

# 二、安装 #

请确保2台服务器，已经安装了docker。

## 163 docker镜像 ##

默认下载镜像太慢了，需要更改为163

2台服务器都修改

vim /etc/docker/daemon.json

内容如下：

{
      "registry-mirrors": ["http://hub-mirror.c.163.com"]
    }

重启docker

systemctl restart docker

## node-exporter ##

2台服务器，都执行一下。用来收集服务器数据的

docker run -d -p 9100:9100 \
      -v "/proc:/host/proc:ro" \
      -v "/sys:/host/sys:ro" \
      -v "/:/rootfs:ro" \
      --net="host" \
      --restart=always \
      --name node-exporter \
      prom/node-exporter

## Prometheus ##

新建目录prometheus，编辑配置文件prometheus.yml

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

内容如下：

global:
      scrape_interval:     60s
      evaluation_interval: 60s
     
    scrape_configs:
      - job_name: prometheus
        static_configs:
          - targets: ['localhost:9090']
            labels:
              instance: prometheus
     
      - job_name: localhost
        static_configs:
          - targets: ['192.168.10.104:9100']
            labels:
              instance: localhost
      - job_name: server20
        static_configs:
          - targets: ['192.168.10.20:9100']
            labels:
              instance: server20

注意：修改IP地址

启动prometheus

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

访问页面：

[http://192.168.10.104:9090/targets][http_192.168.10.104_9090_targets]

等待1分钟，确保是up状态

## Grafana ##

新建空文件夹grafana-storage，用来存储数据

mkdir /opt/grafana-storage

设置权限

chmod 777 -R /opt/grafana-storage

因为grafana用户会在这个目录写入文件，直接设置777，比较简单粗暴！

启动grafana

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

等待1分钟，访问url：

[http://192.168.10.104:3000/][http_192.168.10.104_3000]

默认会先跳转到登录页面，默认的用户名和密码都是admin

![1341090-20181108175033563-1187448777.png][]

登录之后，它会要求你重置密码。你还可以再输次admin密码！

![1341090-20181108175115397-1630657428.png][]

密码设置完成之后，就会跳转到首页

![1341090-20191103172848976-106432171.png][]

点击Add data source

![1341090-20191103172946315-1709421433.png][]

点击下面的Save & Test，如果出现绿色的，说明ok了

# 三、Node Exporter for Prometheus Dashboard 中文版  #

访问链接：

[https://grafana.com/grafana/dashboards/8919/revisions][https_grafana.com_grafana_dashboards_8919_revisions]

下载最新的

![1341090-20191103173119139-1004509394.png][]

点击import

![1341090-20191103173158805-958005745.png][]

点击上传

![1341090-20191103173230125-833324584.png][]

选择下载好的json文件，选择Prometheus

![1341090-20191103173651563-1234435269.png][]

效果如下：

![1341090-20191103173817112-1658465796.png][]

是不是，看着很炫酷啊！！！

# 四、session问题 #

刚刚我用的是谷歌浏览器访问的，没啥问题。

但是我用 edge 浏览器，访问时。输入用户名和密码之后，还依然提示更改密码。

这个时候，直接跳过即可。

但是进入之后，却发现，数据都是空的！！！

![1341090-20191103174249620-1209754905.png][]

点击左侧的admin，就可以看到session列表。

![1341090-20191103174516792-1705366441.png][]

因此，只需要将谷歌浏览器的配置，导入进来即可。

点击管理

![1341090-20191103174628742-1776694930.png][]

选择，点击一下

![1341090-20191103174707583-542880095.png][]

就可以看到数据了

![1341090-20191103174731604-358181711.png][]

重新点击，就可以看到面板了。
