由于我个人Hexo博客使用的是next主题，所以以下均为next主题设置步骤介绍，其它hexo博客主题使用方法类似，建议自己尝试修改。

第一步：添加配置

首先我们需要进入themes\next\layout下的index文件，找到如下代码：

{% block content %}

然后在这段代码的下面添上一行代码：

{% include '_macro/carousel.swig' %}

第二步：添加文件

由于上面添加了文件，所以这里我们需要创建该文件。

在themes\next\layout\macro文件下创建carousel.swig文件。

然后在其中写入以下内容：

{% if theme.carousel.enable %}
<script src="https://cdn.staticfile.org/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/js/bootstrap.min.js"></script>

<style type="text/css">

.glyphicon-chevron-left:before{
    content: "《"
}
.glyphicon-chevron-right:before{
    content: "》"
}

@media (max-width: 767px){
    .rights{
        display: none;
    }
    .carousel{
        width: 100% !important;
        height: 100% !important;
    }
    .slide{
        width: 100% !important;
        height: 100% !important;
    }

}

.carousel{
    width: 100%;
    height: 100%;
    position: relative;
}

.carousel-inner {
  position: relative;
  overflow: hidden;

}
.carousel-inner > .item {

<div width="100%" height="320px" style="border: 0px; overflow: hidden; border-radius: 10px;" scrolling="no">
            
    <div id="myCarousel" class="carousel slide" data-ride="carousel" data-interval="3500" >
        <!-- 轮播（Carousel）指标 -->
        <ol class="carousel-indicators">
        {% set index = 0 %}
        {% for item in theme.carousel.item %}

            <li data-target="#myCarousel" data-slide-to="{{index}}"></li>
            {% set index = index+1 %}

        {% endfor %}
        </ol>
        <!-- 轮播（Carousel）项目 -->
        <div class="carousel-inner" style="height: 280px; border-radius: 10px; width: 100%;">

        {% set act = 0 %}
         {% for item in theme.carousel.item %}
        
            {% if act===0 %}
                <a class="item active" href="{{ url_for(item.link) }}" target="_blank" style="height: 100%;">
                    <img src="{{item.img}}"   style="width: 100%; height: 100%" >
                </a>
                {% set act = 1 %}
                {% elseif act===1 %}
                    <a class="item" href="{{ url_for(item.link) }}" target="_blank" style="height: 100%;">
                        <img src="{{item.img}}"  style="width: 100%; height: 100%;" >
                    </a>
            {% endif %}

        {% endfor %}

     
        </div>
        <!-- 轮播（Carousel）导航 -->
        <a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
            <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
            
        </a>
        <a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
            <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
           
        </a>
    </div> 
</div>

{% endif %}

第三步：配置文件中配置图片及链接

在next主题（其它主题也可以）中的_config.xml主题配置文件中末尾添加如下配置：

#Home carousel map, from means link, img means picture
carousel: 
   enable: true
   item: [
      {
        'link':'文章链接1',
        'img':'图片链接1'
      },
      {
        'link':'文章链接2',
        'img':'图片链接2'
      },
   ]

要有几张轮播图就配置几个数组内容即可，比如我的是：

# 配置首页轮播图
carousel: 
   enable: true
   item: [
      {
        'link':'/messageboard/',
        'img':'https://blogimage-1258928558.cos.ap-guangzhou.myqcloud.com/%E8%BD%AE%E6%92%AD%E5%9B%BE/my-blog.png'
      },
      {
        'link':'https://github.com/996icu/996.ICU',
        'img':'https://blogimage-1258928558.cos.ap-guangzhou.myqcloud.com/%E8%BD%AE%E6%92%AD%E5%9B%BE/996.png'
      },
      {
        'link':'/tags/JVM/',
        'img':'https://blogimage-1258928558.cos.ap-guangzhou.myqcloud.com/%E8%BD%AE%E6%92%AD%E5%9B%BE/JVM.png'
      },
      {
        'link':'/posts/258aee07.html',
        'img':'https://blogimage-1258928558.cos.ap-guangzhou.myqcloud.com/%E8%BD%AE%E6%92%AD%E5%9B%BE/%E5%A4%9A%E7%BA%BF%E7%A8%8B.png'
      },
      {
        'link':'/tags/博客/',
        'img':'https://blogimage-1258928558.cos.ap-guangzhou.myqcloud.com/%E8%BD%AE%E6%92%AD%E5%9B%BE/hexo.png'
      },
      {
        'link':'https://promotion.aliyun.com/ntms/act/campus2018.html',
        'img':'https://blogimage-1258928558.cos.ap-guangzhou.myqcloud.com/%E8%BD%AE%E6%92%AD%E5%9B%BE/19010107.jpg'
      },
   ]

第四步：清除缓存，重新生成渲染

素质三连：hexo clean && hexo g && hexo s即可本地看到效果。

ps:注意：开启这种轮播图形式的时候，在主题配置文件中不要开启fancybox，这个设置需要设置为false，不然在点击图片进行跳转时会出现The requested content cannot be loaded.Please try again later.错误
