在个人电脑上安装TiDB

4. Local Deployment from Binary Tarball

   This guide provides installation instructions for all TiDB components on a single developer machine. It is intended for evaluation purposes, and does not match the recommended usage for production systems.

   See also testing environment and production enviroment deployment.

   The following local TCP ports will be used:

   Component	Port	Protocol	Description
   TiDB	4000	TCP	the communication port for the application and DBA tools
   TiDB	10080	TCP	the communication port to report TiDB status
   TiKV	20160	TCP	the TiKV communication port
   PD	2379	TCP	the communication port between TiDB and PD
   PD	2380	TCP	the inter-node communication port within the PD cluster

   Prepare

   This guide is for deployment on Linux only. It is recommended to use RHEL/CentOS 7.3 or higher. TiKV requires you to raise the open files limit:

   tidbuser="tidb"
   
   cat << EOF > /tmp/tidb.conf
   $tidbuser        soft        nofile        1000000
   $tidbuser hard nofile 1000000 EOF sudo cp /tmp/tidb.conf /etc/security/limits.d/ sudo sysctl -w fs.file-max=1000000

   See the production deployment optional kernel tuning parameters.

   Create a database running user account

   1. Log in to the machine using the root user account and create a database running user account (tidb) using the following command:

5. # useradd tidb -m

6. Switch the user from root to tidb by using the following command. You can use this tidb user account to deploy your TiDB cluster.

2. # su - tidb

Download the official binary package

# Download the package.
$ wget http://download.pingcap.org/tidb-v3.0-linux-amd64.tar.gz http://download.pingcap.org/tidb-v3.0-linux-amd64.sha256

# Check the file integrity. If the result is OK, the file is correct.
$ sha256sum -c tidb-v3.0-linux-amd64.sha256

# Extract the package.
$ tar -xzf tidb-v3.0-linux-amd64.tar.gz
$ cd tidb-v3.0-linux-amd64

Start

Follow the steps below to start PD, TiKV and TiDB:

1. Start PD.

1. $ ./bin/pd-server --data-dir=pd \
                   --log-file=pd.log &

2. Start TiKV.

3. $ ./bin/tikv-server --pd="127.0.0.1:2379" \
                     --data-dir=tikv \  --log-file=tikv.log &

4. Start TiDB.

5. $ ./bin/tidb-server --store=tikv \
                     --path="127.0.0.1:2379" \  --log-file=tidb.log &

6. Use the MySQL client to connect to TiDB.

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