Minimal Deployment Topology

This document describes the minimal deployment topology of TiDB clusters.

Topology information

Instance	Count	Physical machine configuration	IP	Configuration
TiDB	3	16 VCore 32GB * 1	10.0.1.1 10.0.1.2 10.0.1.3	Default port Global directory configuration
PD	3	4 VCore 8GB * 1	10.0.1.4 10.0.1.5 10.0.1.6	Default port Global directory configuration
TiKV	3	16 VCore 32GB 2TB (nvme ssd) * 1	10.0.1.7 10.0.1.8 10.0.1.9	Default port Global directory configuration
Monitoring & Grafana	1	4 VCore 8GB * 1 500GB (ssd)	10.0.1.10	Default port Global directory configuration

For detailed descriptions of the configuration items in the above TiDB cluster topology file, see Topology Configuration File for Deploying TiDB Using TiUP.

Note:

• You do not need to manually create the tidb user in the configuration file. The TiUP cluster component automatically creates the tidb user on the target machines. You can customize the user, or keep the user consistent with the control machine.
• If you configure the deployment directory as a relative path, the cluster will be deployed in the home directory of the user.
