You can log in to the target ECS node for troubleshooting, monitoring its performance, or executing custom scripts.
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.
- 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 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 Operation column of the ECS.
For details, see Login Using VNC.
- SSH
This mode applies only to ECSs running Linux. You can 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 Operation column of the ECS to view the connection status and ECS status.
- When you log in to a Linux node from Windows, 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.
