无法从Amazon EC2实例Linux框连接到Internet [英] Not able to connect to internet from Amazon EC2 instance linux box

问题描述

在Amazon EC2实例中，我已将安全组的入站/出站设置为MY-IP地址.

In the amazon EC2 instance, i have set the set the inbound/outbound of security group to MY-IP address.

当我尝试安装mysql客户端或其他软件时，它会说连接超时.

When i try to install the mysql client or some other software, its saying connection timeout.

但是当我将入站/出站设置到任何地方(即0.0.0.0/00)时，便可以安装该软件.

But when i make the inbound/outbound to anywhere ie 0.0.0.0/00, then i am able to install the software.

但是我不想向所有人公开EC2实例请求.

But i don't want to expose the EC2 instance requests to everyone.

How to connect to Internet and install the software with restricted security groups. Please can u help out on this.

推荐答案

要能够自由访问Internet，您应该允许传出网络流量.

To be able to access Internet freely, you should allow outgoing network traffic.

为此，请在EC2安全组中为all traffic至0.0.0.0/0创建一个outbound rule.这是EC2的默认设置，不应该成为安全问题.

To do so, create an outbound rule for all traffic to 0.0.0.0/0 in your EC2 Security Group. This is a default setting with EC2 and it shouldn't be a security concern.
