Minimal Deployment Topology

This document describes the minimal deployment topology of TiDB clusters.

Topology information

Instance	Count	Physical machine configuration	IP	Configuration
TiDB	2	16 VCore 32 GiB 100 GiB for storage	10.0.1.1 10.0.1.2	Default port Global directory configuration
PD	3	4 VCore 8 GiB 100 GiB for storage	10.0.1.4 10.0.1.5 10.0.1.6	Default port Global directory configuration
TiKV	3	16 VCore 32 GiB 2 TiB (NVMe SSD) for storage	10.0.1.7 10.0.1.8 10.0.1.9	Default port Global directory configuration
Monitoring & Grafana	1	4 VCore 8 GiB 500 GiB (SSD) for storage	10.0.1.10	Default port Global directory configuration

Topology templates

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.
