tiup cluster enable

The tiup cluster enable command is used to set the auto-enabling of the cluster service after a machine is restarted. This command enables the auto-enabling of the service by executing systemctl enable <service> at the specified node.

Note

When all clusters are shut down and restarted, the order of service startup is determined by the node's operating system startup order. When the restart order 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 gives up if TiKV is restarted multiple times while PD is not found).
