tiup cluster enable

The command tiup cluster enable is used to set the self-start of the cluster service after the machine restarts. This command will go to the specified node and execute systemctl enable to enableAutostart of the service.

Note

When the cluster is all shut down and restarted, the order in which the services are started is determined by the order in which the operating systems of the nodes are started.When the restart sequence is incorrect, in some cases, the restarted cluster still cannot provide services (for example, if TiKV is started first but PD is not started, systemd restarts TiKV several times and fails to find PD, and it will give up).
