Mac Login Amazon Cloud Server error: Permission denied (PublicKey).

Application for Amazon Cloud Server EC2, instance for Ubuntu system

First, open the terminal, locate the folder where the key is placed;

Second, ensure that the private key is not publicly visible:

chmod 400 key file name. PEM

Three, two ways to connect to the cloud server: (assuming that the instance of the public IP is: 11.22.33.44)

Ssh-i key file name. PEM [email protected]

Ssh-i key file name. PEM [email protected]

Both of these methods are error:

Permission denied (PublicKey).

Iv. Solutions:

The following paragraph is in the official Amazon documentation:

Get The default user name for the AMI so used to launch your instance

• For a Amazon Linux AMI, the user name is ec2-user .

• For a Centos AMI, the user name is centos .

• For a Debian AMI, the user name is admin or root .

• For a Fedora AMI, the user name is ec2-user or fedora .

• For a RHEL AMI, the user name is ec2-user or root .

• For a SUSE AMI, the user name is ec2-user or root .

• For a Ubuntu AMI, the user name is ubuntu or root .

• Otherwise, if ec2-user and root don ' t work, check with the AMI provider.

The last one shows the use of ec2-user and root can not connect, so need to try a bit more, because I installed the Ubuntu system, the connection command directly into the Ec2-user Ubuntu, the perfect connection.
