Deploy TiDB Using Docker

This document 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.

Preparation

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
  

Multi nodes deployment

Assume we have 6 machines with the following details:

1. Start PD

Start PD1 on the host1

docker run -d --name pd1 \
  -p 2379:2379 \
  -p 2380:2380 \
  -v /etc/localtime:/etc/localtime:ro \
  -v /data:/data \
  pingcap/pd:latest \
  --name="pd1" \
  --data-dir="/data/pd1" \
  --client-urls="http://0.0.0.0:2379" \
  --advertise-client-urls="http://192.168.1.101:2379" \
  --peer-urls="http://0.0.0.0:2380" \
  --advertise-peer-urls="http://192.168.1.101:2380" \
  --initial-cluster="pd1=http://192.168.1.101:2380,pd2=http://192.168.1.102:2380,pd3=http://192.168.1.103:2380"

Start PD2 on the host2

docker run -d --name pd2 \
  -p 2379:2379 \
  -p 2380:2380 \
  -v /etc/localtime:/etc/localtime:ro \
  -v /data:/data \
  pingcap/pd:latest \
  --name="pd2" \
  --data-dir="/data/pd2" \
  --client-urls="http://0.0.0.0:2379" \
  --advertise-client-urls="http://192.168.1.102:2379" \
  --peer-urls="http://0.0.0.0:2380" \
  --advertise-peer-urls="http://192.168.1.102:2380" \
  --initial-cluster="pd1=http://192.168.1.101:2380,pd2=http://192.168.1.102:2380,pd3=http://192.168.1.103:2380"

Start PD3 on the host3

docker run -d --name pd3 \
  -p 2379:2379 \
  -p 2380:2380 \
  -v /etc/localtime:/etc/localtime:ro \
  -v /data:/data \
  pingcap/pd:latest \
  --name="pd3" \
  --data-dir="/data/pd3" \
  --client-urls="http://0.0.0.0:2379" \
  --advertise-client-urls="http://192.168.1.103:2379" \
  --peer-urls="http://0.0.0.0:2380" \
  --advertise-peer-urls="http://192.168.1.103:2380" \
  --initial-cluster="pd1=http://192.168.1.101:2380,pd2=http://192.168.1.102:2380,pd3=http://192.168.1.103:2380"

2. Start TiKV

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 \
  --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"

Start TiKV2 on the host5

docker run -d --name tikv2 \
  -p 20160:20160 \
  -v /etc/localtime:/etc/localtime:ro \
  -v /data:/data \
  pingcap/tikv:latest \
  --addr="0.0.0.0:20160" \
  --advertise-addr="192.168.1.105:20160" \
  --data-dir="/data/tikv2" \
  --pd="192.168.1.101:2379,192.168.1.102:2379,192.168.1.103:2379"

Start TiKV3 on the host6

docker run -d --name tikv3 \
  -p 20160:20160 \
  -v /etc/localtime:/etc/localtime:ro \
  -v /data:/data \
  pingcap/tikv:latest \
  --addr="0.0.0.0:20160" \
  --advertise-addr="192.168.1.106:20160" \
  --data-dir="/data/tikv3" \
  --pd="192.168.1.101:2379,192.168.1.102:2379,192.168.1.103:2379"

3. Start TiDB

Start TiDB on the host1

docker run -d --name tidb \
  -p 4000:4000 \
  -p 10080:10080 \
  -v /etc/localtime:/etc/localtime:ro \
  pingcap/tidb:latest \
  --store=tikv \
  --path="192.168.1.101:2379,192.168.1.102:2379,192.168.1.103:2379"

4. Use the MySQL client to connect to TiDB

Install the MySQL client on host1 and run:

mysql -h 127.0.0.1 -P 4000 -u root -D test

show databases;

+--------------------+
| Database           |
+--------------------+
| INFORMATION_SCHEMA |
| PERFORMANCE_SCHEMA |
| mysql              |
| test               |
+--------------------+
4 rows in set (0.00 sec)

How to customize the configuration file

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 \
  -v /path/to/config/pd.toml:/pd.toml:ro \
  pingcap/pd:latest \
  --name="pd1" \
  --data-dir="/data/pd1" \
  --client-urls="http://0.0.0.0:2379" \
  --advertise-client-urls="http://192.168.1.101:2379" \
  --peer-urls="http://0.0.0.0:2380" \
  --advertise-peer-urls="http://192.168.1.101:2380" \
  --initial-cluster="pd1=http://192.168.1.101:2380,pd2=http://192.168.1.102:2380,pd3=http://192.168.1.103:2380" \
  --config="/pd.toml"
