阿里云ECS安全组策略简单来说就是开放服务器端口供外界来使用，端口举个例子，常见的http默认的端口就是80，MySQL数据库的端口是3306，FTP的端口是21，宝塔面板的自定义初始端口是8888等等很多端口，下面给大家介绍一下端口是什么。
阿里云ECS禁封端口号
安全组是一种虚拟防火墙，具备状态检测和数据包过滤功能，用于在云端划分安全域。您可以通过配置安全组规则，允许或禁止安全组内的ECS实例对公网或私网的访问。
云服务器 ECS > 安全 > 安全组 > 安全组概述
由于出于对互联网的开放负责，阿里云目前已知只将25端口调用465端口禁封掉 。
25端口主要是用于邮件发送服务的端口，其实主要是阿里云想推广自家邮件服务，不过可以理解。
ECS站点需要开放那些端口
- FTP外放端口 21/21
- 宝塔面板端口 8888/8888
- https开放端口 443/443
- 数据库访问权限 3306/3306
除了自定义端口外，阿里云服务器还自己开启了-1/22/3389端口，这三个端口均为系统创建规则。

]以上配置是我阿里云服务器外网线圈组配置，基本就是把用到的服务启用的端口都设置了一下，此配置适用于门户网站或者博客环境，就到这吧！
