Logging In to a Node

Notes and Constraints

  • If you use SSH to log in to a node (an ECS), ensure that the ECS already has an EIP (a public IP address).
  • Only login to a running ECS is allowed.
  • Only the user linux can log in to a Linux server.

Login Modes

You can log in to an ECS in either of the following modes:

  • Management console (VNC)

    If an ECS has no EIP, log in to the ECS console and click Remote Login in the same row as the ECS.

  • SSH

    This mode applies only to ECSs running Linux. Usually, you can use a remote login tool, such as PuTTY, Xshell, and SecureCRT, to log in to your ECS. If none of the remote login tools can be used, log in to the ECS console and click Remote Login in the same row as the ECS to view the connection status and running status of the ECS.

    • When you use the Windows OS to log in to a Linux node, set Auto-login username to linux.
    • The CCE console does not support node OS upgrade. Do not upgrade the node OS using the yum update command. Otherwise, the container networking components will be unavailable.
