Logging In to a Node

Prerequisites

• Before you log in to a node using SSH, ensure the SSH port (22 by default) is enabled in the security group of the node. For details, see Configuring Security Group Rules.
• Before you log in to a node (an ECS) via SSH over the Internet, ensure the ECS already has an EIP bound.
• Only a running ECS can be logged in to.
• Only user root 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. You can typically use a remote login tool like PuTTY, Xshell, or 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 log in to a Linux node from Windows, set Auto-login username to root.
  • 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.
