阿里云CDN怎么用
阿里云CDN（Content Delivery Network）是阿里云为用户提供的一种加速访问服务。它利用云计算和分布式存储技术，将内容缓存在全球各个节点上，实现网站动态加速和负载均衡。但是，如何使用阿里云CDN呢？下面我们来介绍一下。
中文步骤
1. 开通CDN服务。在阿里云官网打开CDN控制台，单击【开通】,选择需要加速的源站，填写加速域名并确认费用，完成开通。
2. 添加域名。在前面步骤中，您已经完成了加速域名的绑定。这一步将为加速域名添加CDN服务。
3. 配置CNAME。进入您的DNS管理页面，在相应的域名中添加一个CNAME记录，将其设置为阿里云CDN节点的地址。
4. 设置缓存规则。缓存规则是用来指定在CDN节点中存储哪些文件，以及缓存时间等参数。如果您有特别的需求，可以根据实际情况进行自定义。
5. 开启HTTPS。HTTPS是通过加密方式保证数据传输安全的协议。阿里云CDN支持各种证书类型，您可以选择适合自己的证书类型，并按照相应的文档开启HTTPS服务。
6. 开启访问日志。访问日志是CDN服务提供的一种记录CDN节点访问情况的功能。通过访问日志，用户可以了解CDN服务的访问情况和流量分布情况。您可以在控制台中开启访问日志，并根据需求进行下载和分析。
