推荐答案

基本上，您需要一个私钥文件才能通过 SSH 登录到您的 EC2.按照以下步骤创建一个:

Basically, you need a private-key file to login into your EC2 via SSH. Follow these steps to create one:

• 转到https://console.aws.amazon.com/ec2/home &登录您现有的亚马逊帐户.
• 点击 LHS 上的密钥对"或 https://console.aws.amazon.com/ec2/home?region=us-east-1#s=KeyPairs.
  • 您应该会看到您(或在 EC2 创建过程中)生成的 KEY 列表.
  • 如果您没有看到任何或丢失了您的私钥，请单击创建密钥对".
  • 输入一个唯一的名称并按回车键.
  • 将出现一个下载面板供您保存私钥，保存.
  • 使用文件权限0600"将其保存在某处
  • Go https://console.aws.amazon.com/ec2/home & sign in to your existing Amazon account.
  • Click on "Key Pairs" on LHS or https://console.aws.amazon.com/ec2/home?region=us-east-1#s=KeyPairs.
    • You should see the list of KEYs generated by you (or during EC2 creation process).
    • Click on "Create Key Pair" if you don't see any or you lost your private-key.
    • Enter a unique name and hit enter.
    • A download panel will appear for you to save the private-key, save it.
    • Keep it somewhere with the file permission "0600"
    • 您应该会看到 ec2-instances 的列表，如果没有看到，请创建一个.
    • 点击 EC2 机器并记下公共 DNS 地址.
    • ssh -i/path/to/private-key root@<ec2-public-dns-address> - 根据您的发行版选择，最新版本中已避免使用 root 用户名ec2-user 或 ubuntu 作为您的用户名.
    • 按回车
    • 就是这样.
    • ssh -i /path/to/private-key root@<ec2-public-dns-address> - the root username has been avoided in the latest releases, based on your distribution select ec2-user or ubuntu as your username.
    • hit Enter
    • That's it.
