telnet <ip> 22 或者 80 ,看下端口是否可访问, 如果不能访问可以看下 1: 实例附加的安全组是否放开了对应的端口策略; https://docs.aws.amazon.com/zh_cn/AWSEC2/latest/UserGuide/ec2-security-groups.html 2: 对应云服务器所在的子网 NACL是否自己做了限制(默认是全放行) https://docs.aws.amazon.com/zh_cn/vpc/latest/userguide/vpc-network-acls.html 3: 检查云服务所在的子网路由是否可以被公网访问(看下是否有路由0.0.0.0 - igw-xxxxx)
