Resetting the Password for a FlexusL Instance

Constraints

• 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.

• You have installed the one-click password reset plug-in.

  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.

1. Log in to the FlexusL console.
2. Reset the password for logging in to one or more servers.
