TiDB Ansible Common Operations

This guide describes the common operations when you administer a TiDB cluster using TiDB Ansible.

Start a cluster

$ ansible-playbook start.yml

This operation starts all the components in the entire TiDB cluster in order, which include PD, TiDB, TiKV, and the monitoring components.

Stop a cluster

$ ansible-playbook stop.yml

This operation stops all the components in the entire TiDB cluster in order, which include PD, TiDB, TiKV, and the monitoring components.

Clean up cluster data

$ ansible-playbook unsafe_cleanup_data.yml

This operation stops the TiDB, Pump, TiKV and PD services, and cleans up the data directory of Pump, TiKV and PD.

Destroy a cluster

$ ansible-playbook unsafe_cleanup.yml

This operation stops the cluster and cleans up the data directory.

Note:

If the deployment directory is a mount point, an error will be reported, but implementation results remain unaffected, so you can ignore it.
