Setting or Resetting a Password

You can set or reset the password for logging in to one or more cloud servers at a time.

A FlexusL instance does not have an initial password. You need to set a password when you use the FlexusL instance for the first time.
If the password is lost or expires, you can reset the password.

You can reset the password only when the server is in Stopped or Running state. If you reset the password when the server is in Running state, the password change will be applied only after the server is restarted.

The one-click password reset plug-in must have been installed.
If a private Linux image is created from a server on another cloud platform or downloaded from a third party, the image may not have the password reset plug-in installed. Servers created from such images do not support password reset. For details about how to install the one-click password reset plug-in and reset the password, see What Should I Do If the Password Cannot Be Reset After I Use a Private Linux Image to Create a FlexusL Instance or Change the OS of an Existing Instance and I Forgot the Initial Password of the Private Image?
Do not delete the password reset processes CloudResetPwdAgent and CloudResetPwdUpdateAgent, or the password reset will be unavailable.
Ensure that DHCP is enabled in the VPC which the server belongs to.
Ensure that the network is normal.
