03_使用 Docker Compose 快速構建 TiDB 集羣

1、安裝docker.
(01_centos 安裝docker)
https://docs.docker.com/install/linux/docker-ce/centos/

2、下載並安裝 tidb-docker-compose
https://github.com/pingcap/tidb-docker-compose

可能存在問題：（版本的問題）
1、tidb-docker-compose. clone 碰到錯誤

git clone https://github.com/pingcap/tidb-docker-compose.git
正克隆到 'tidb-docker-compose'...
fatal: unable to access 'https://github.com/pingcap/tidb-docker-compose.git/': Peer reports incompatible or unsupported protocol version.

3、https://docs.docker.com/compose/install/

dockersudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

3、創建並啓動集羣

1、cd tidb-docker-compose && docker-compose pull
  
-bash: cd: tidb-docker-compose: 沒有那個文件或目錄
  
2、sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
3、cd tidb-docker-compose && docker-compose pull
-bash: /usr/local/bin/docker-compose: 權限不夠
4、chmod -R 777 /usr/local/bin/docker-compose
5、cd /usr/local/tidb-docker-compose/ & docker-compose pull
6、docker-compose up -d

4、訪問集羣

mysql -h 127.0.0.1 -P 4000 -u root
