How Can I Log in to the Target Server with the root Username and Password via SSH After Migration?

Symptom

AWS Linux uses key login by default and only supports the ec2-user account. Therefore, the target server cannot be logged in to using the root username and password after migration.

Solution

  1. Log in to the target server using VNC. VNC supports password login for the root user. For details, see Logging In to a Linux ECS Using VNC.
  2. Run the following command to set PasswordAuthentication to yes in the sshd configuration file: 

    vim /etc/ssh/sshd_config

  3. Run the following command to add PermitRootLogin: 

    PermitRootLogin yes

  4. Run the following command to restart sshd and log in as the root user using a password: 

    sudo /sbin/service sshd restart
