2.下载安装包
https://prometheus.io/download/ （需要的安装包都可以下载）
wget https://github.com/prometheus/prometheus/releases/download/v2.3.2/prometheus-2.3.2.linux-amd64.tar.gz

服务端（监控server）
3.安装prometheus
部署到/usr/local/目录
promethus不用编译安装，解压目录中有配置文件与启动文件
tar -zxvf prometheus-2.3.2.linux-amd64.tar.gz -C /usr/local/
cd /usr/local/ && mv prometheus-2.3.2.linux-amd64/ prometheus
验证
[root@prometheus local]# cd prometheus/
[root@prometheus prometheus]# ./prometheus --version
prometheus, version 2.3.2 (branch: HEAD, revision: 71af5e29e815795e9dd14742ee7725682fa14b7b)
build user: root@5258e0bd9cc1
build date: 20180712-14:02:52
go version: go1.10.3

备份配置文件并配置
cp prometheus.yml prometheus.yml-bak

my global config

global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.

scrape_timeout is set to the global default (10s).

Alertmanager configuration

alerting:
alertmanagers:

• static_configs:
  • targets:

    - alertmanager:9093

Load rules once and periodically evaluate them according to the global ‘evaluation_interval‘.

rule_files:

- "first_rules.yml"

- "second_rules.yml"

A scrape configuration containing exactly one endpoint to scrape:

Here it‘s Prometheus itself.

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: [‘192.168.244.128:9090‘,‘192.168.244.129:8080‘]

添加需要监控的服务器IP和端口

启动（后台启动）
./prometheus --config.file=prometheus.yml &
然后我们可以访问 http://<服务器IP地址>:9090，验证Prometheus是否已安装成功，web显示应该如下

通过点击下拉栏选取指标，点击”Excute” 我们能够看到Prometheus的性能指标。
点击”status”可以查看相关状态。

4.node_exporter安装
wget https://github.com/prometheus/node_exporter/releases/download/v0.16.0/node_exporter-0.16.0.linux-amd64.tar.gz
解压并安装
tar xf node_exporter-0.16.0.linux-amd64.tar.gz C /usr/local/
cd /usr/local/ && mv mv node_exporter-0.16.0 node_exporter
cd node_exporter/ && ./node_exporter &

返回一大堆指标

5.grafana安装
wget https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-5.2.3-1.x86_64.rpm
sudo yum localinstall grafana-5.2.3-1.x86_64.rpm
服务端图像呈现组件安装
yum install fontconfig freetype* urw-fonts -y
开启系统默认启动
systemctl enable grafana-server
启动服务
systemctl start grafana-server
查看服务是否正常启动
systemctl status grafana-server
[root@prometheus ~]# systemctl status grafana-server
● grafana-server.service - Grafana instance

客户端（被监控）
6.安装cAdvisor 来收集容器信息 所有节点运行以下命令来安装cAdvisor
docker run \
--volume=/:/rootfs:ro \
--volume=/var/run:/var/run:rw \
--volume=/sys:/sys:ro \
--volume=/var/lib/docker/:/var/lib/docker:ro \
--publish=8080:8080 \
--detach=true \
--name=cadvisor \
--net=host \
-v "/etc/localtime:/etc/localtime" \
google/cadvisor:latest

为grafana添加Prometheus数据源

导入监控模板
https://grafana.com/dashboards?search=docker 多种docker 监控模板
