Get the code, build, and run

Prerequisites

• git: The TiDB source code is hosted on GitHub as a git repository. To work with the git repository, please install git.

• go: TiDB is a Go project. Therefore, you need a working Go environment to build it. See the previous Install Golang section to prepare the environment.

• gcc: gcc command is required to use cgo while building. To install gcc, search for appropriate install guide for your OS.

• mysql client (optional): After building TiDB from source, you can use the official MySQL client to connect to TiDB. It is not required if you want to build TiDB only.

Note:

TiDB could compile and run on Windows 10. However, it is not expected to be deployed on Windows, where you might encounter many compatibility problems. To have a better experience, we recommend you install WSL2 first.

Clone

Clone the source code to your development machine:

git clone https://github.com/pingcap/tidb.git

Build

Build TiDB from the source code:

cd tidb
make

Run

Now that you have the tidb-server binary under the bin directory, execute it for a TiDB server instance:

./bin/tidb-server

This starts the TiDB server listening on port 4000 with embedded unistore.

Connect

You can use the official MySQL client to connect to TiDB:

mysql -h 127.0.0.1 -P 4000 -u root -D test --prompt="tidb> " --comments

where

• -h 127.0.0.1 sets the Host to local host loopback interface

• -P 4000 uses port 4000

• -u root connects as root user (-p not given; the development build has no password for root.)

• -D test uses the Schema/Database test

• --prompt "tidb> " sets the prompt to distinguish it from a connection to MySQL

• --comments preserves comments like /*T![clustered_index NONCLUSTERED */ instead of stripping them when sending the query to the server.

If you encounter any problems during your journey, do not hesitate to reach out on the TiDB Internals forum.
