Why Is the Hostname of My ECS Restored to the Original Name After the ECS Is Restarted?

The following uses an ECS running CentOS 7 as an example:

  1. Log in to the Linux ECS and view the Cloud-Init configuration file.
  2. In the /etc/cloud/cloud.cfg file, comment out or delete update_hostname.
    • update_hostname indicates that the hostname is changed in Cloud-Init each time the ECS is restarted.
    • For an ECS created from a public image, Cloud-Init has been installed on it by default. You do not need to manually install Cloud-Init for it. For details about how to modify a private image, see Installing Cloud-Init.
