Local accounts on ACOS nodes

ACOS nodes support the following three types of local accounts:

Local account Description Notes
root A default account. Remote login via SSH is not allowed by default. You can use this account to manage ACOS nodes.
  • Do not delete this account.
  • It is strongly recommended not to enable the root account to log in remotely via SSH.
  • You must have root privileges to upgrade the cluster using commands.
arcfra A default account that supports SSH remote login by default. You can use this account to remotely connect to the ACOS node via the SSH protocol.
  • Do not delete this account.
  • Do not change the account configuration in /etc/sudoers.
  • After logging in to the node with this account, you must switch to the root account to perform operations. Execute the sudo su command to realize a smooth account switch without entering the password.
Other local accounts Accounts created by the root account. Their permissions are determined by the root account. You can create a new local account for SSH remote login. -
