本文基于 Docker进行安装

## 安装 node-exporter ##

node-exporter 是 Prometheus 官方维护的，用来监控 Linux 系统指标的组件。**可以选择不安装**。

### 1.拉取镜像 ###

docker pull prom/node-exporter

### 2.启动 node-exporter ###

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

### 3.验证是否启动成功 ###

访问 `http://192.168.20.10:9100/metrics`

## 安装Prometheus ##

### 1.拉取镜像 ###

docker pull prom/prometheus

### 2.新建 prometheus 配置文件 ###

mkdir /etc/prometheus
    vim /etc/prometheus/prometheus.yml

**内容：**

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

**备注：**

> 如果没有安装 node-exporter 可以不配置 Linux 这一项，如果配置需要注意 **192.168.10.20** 不能为 **127.0.0.1** 或 **localhost**

### 3.运行 prometheus ###

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

### 4.验证是否启动成功 ###

访问 `http://192.168.20.10:9090/graph`

访问 `http://192.168.20.10:9090/targets`

## 安装 Grafana ##

### 1.拉取镜像 ###

docker pull grafana/grafana

### 2.配置目录 ###

mkdier /var/lib/grafana
    chmod -R ugo+w /var/lib/grafana

### 3.启动 Grafana ###

docker run -d \
    	--name grafana \
    	-p 3000:3000 \
    	-v /var/lib/grafana:/var/lib/grafana \
    	grafana/grafana

### 4.登录 ###

访问 `http://192.168.20.10:3000/`

默认账号密码是 `admin/admin`，登录后会让修改密码。

## 5.添加数据源 ##
