This page shows you how to manually deploy a multi-node TiDB cluster on multiple machines using Docker.
To learn more, see TiDB architecture and Software and Hardware Recommendations.
Warning:
This is for testing only. DO NOT USE in production! Please deploy TiDB with our Ansible solution or TiDB Operator in Kubernetes in production.
Before you start, make sure that you have:
-
Installed the latest version of Docker
-
Pulled the latest images of TiDB, TiKV and PD from Docker Hub. If not, pull the images using the following commands:
docker pull pingcap/tidb:latest docker pull pingcap/tikv:latest docker pull pingcap/pd:latest
Assume we have 6 machines with the following details:
Host Name | IP | Services | Data Path |
---|---|---|---|
host1 | 192.168.1.101 | PD1 & TiDB | /data |
host2 | 192.168.1.102 | PD2 | /data |
host3 | 192.168.1.103 | PD3 | /data |
host4 | 192.168.1.104 | TiKV1 | /data |
host5 | 192.168.1.105 | TiKV2 | /data |
host6 | 192.168.1.106 | TiKV3 | /data |

Start TiKV1 on the host4
docker run -d --name tikv1 \
-p 20160:20160 \
-v /etc/localtime:/etc/localtime:ro \
-v /data:/data \
pingcap/tikv:latest \

Install the MySQL client on host1 and run:
$ mysql -h 127.0.0.1 -P 4000 -u root -D test
mysql> show databases;
+--------------------+
| Database |

4 rows in set (0.00 sec)
The TiKV and PD can be started with a specified configuration file, which includes some advanced parameters, for the performance tuning.
Assume that the path to configuration file of PD and TiKV on the host is /path/to/config/pd.toml
and /path/to/config/tikv.toml
You can start TiKV and PD as follows:
docker run -d --name tikv1 \
-p 20160:20160 \
-v /etc/localtime:/etc/localtime:ro \
-v /data:/data \
-v /path/to/config/tikv.toml:/tikv.toml:ro \
pingcap/tikv:latest \
--addr="0.0.0.0:20160" \
--advertise-addr="192.168.1.104:20160" \
--data-dir="/data/tikv1" \
--pd="192.168.1.101:2379,192.168.1.102:2379,192.168.1.103:2379" \
--config="/tikv.toml"
docker run -d --name pd1 \
-p 2379:2379 \
-p 2380:2380 \
-v /etc/localtime:/etc/localtime:ro \
-v /data:/data \
