一、部署方式选择
部署方式选择
tidb: TiDB is an open source distributed HTAP database compatible with the MySQL protocol
通过查阅官方文档和网友踩坑经验,我们学习测试时就就直接使用官网推荐的Docker Compose方式快速构建TiDB集群即可(或者使用单机版)
二、TiDB-Local单机版
部署TiDB就是摆在我们面前的第一节课，其实有很多的部署方式，限于环境，我先开始琢磨单机版如何部署。
在Centos 6的版本中如果要部署，这个难度还是比较大的，而且会有很多未知的坑，根据官方的建议，是需要在Centos 7以上的版本中，否则glibc的版本问题会很快碰到。
我们安装一套Centos7，采用快速的单机部署的方式来尝鲜。

TiDB-Docker集群版
1.准备环境
确保你的机器上已安装：
Docker（17.06.0 及以上版本）
Docker Compose
Git
2.快速部署
下载 tidb-docker-compose
git clone GitHub - pingcap/tidb-docker-compose
3.创建并启动集群
获取最新 Docker 镜像：
cd tidb-docker-compose && docker-compose pull && docker-compose up -d
注意:
得先启动Docker
sudo systemctl start docker
再执行上面的docker-compose命令
4.访问集群
mysql -h 127.0.0.1 -P 4000 -u root
[root@node01 tidb-docker-compose]# mysql -h 127.0.0.1 -P 4000 -u root
Welcome to the MySQL monitor. Commands end with ; or \\g.
Your MySQL connection id is 1
