如何通过ssh连接到AWS实例?

我有:

Signed up at AWS; Created a public key and a certificate at AWS website and saved them to disk; Went to my console and created environment variables: $ export JAVA_HOME=/usr/lib/jvm/java-6-openjdk/ $ export EC2_CERT=/home/default/aws/cert-EBAINCRNWHDSCWWIHSOKON2YWGJZ5LSQ.pem $ export EC2_PRIVATE_KEY=/home/default/aws/pk-EBAINCRNWHDSCWWIHSOKON2YWGJZ5LSQ.pem Told AWS API to use this keypair and saved the keypair to file: $ ec2-add-keypair ec2-keypair > ec2-keypair.pem Started an AWS Ubuntu 9 instance using this keypair: $ ec2-run-instances ami-ed46a784 -k ec2-keypair Attempted to establish a ssh connection to the instance: $ ssh -v -i ec2-keypair.pem ubuntu@ec2-174-129-185-190.compute-1.amazonaws.com OpenSSH_5.1p1 Debian-5ubuntu1, OpenSSL 0.9.8g 19 Oct 2007 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to ec2-174-129-185-190.compute-1.amazonaws.com [174.129.185.190] port 22. debug1: Connection established. debug1: identity file ec2-keypair.pem type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.1p1 Debian-5ubuntu1 debug1: match: OpenSSH_5.1p1 Debian-5ubuntu1 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.1p1 Debian-5ubuntu1 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-cbc hmac-md5 none debug1: kex: client->server aes128-cbc hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host 'ec2-174-129-185-190.compute-1.amazonaws.com' is known and matches the RSA host key. debug1: Found key in /home/default/.ssh/known_hosts:11 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: ec2-keypair.pem debug1: read PEM private key done: type RSA debug1: Authentications that can continue: publickey debug1: No more authentication methods to try.

当前回答

使用……

# chmod 400 ec2-keypair.pem

不要使用600权限,否则可能会意外覆盖您的密钥。

其他回答

对于Ubuntu实例:

chmod 600 ec2-keypair.pem
ssh -v -i ec2-keypair.pem ubuntu@ec2-174-129-185-190.compute-1.amazonaws.com

对于其他情况,你可能不得不使用ec2-user而不是ubuntu。

我所使用的大多数EC2 Linux映像默认只创建了根用户。

参见:http://www.youtube.com/watch?v=WBro0TEAd7g

连接有2个步骤:

Chmod 400在你的私钥上,像这样其他人不能访问你的密钥:

chmod 400 toto.pem

要在SSH中连接到你的实例,你需要知道你实例的公共IP地址:

ssh -i toto.pem ec2-user@XX.XX.XX.XXX

希望能有所帮助!

对于Debian EC2实例,用户为admin。

Canonical发布的版本默认使用'ubuntu'用户,任何使用ubuntu映像登录这里的人都会遇到相同的问题。

这招对我很管用:

ssh-keygen -R <server_IP>

删除存储在工作站上的旧密钥 也与而不是

然后做同样的SSH再次工作:

ssh -v -i <your_pem_file> ubuntu@<server_IP>

在ubuntu实例中,用户名是:ubuntu 在Amazon Linux AMI上,用户名是:ec2-user

我不需要从映像重新创建实例。
