👉 本文共约2020个字，系统预计阅读时间或需8分钟。
一、快速部署
参考连接：https://docs.pingcap.com/zh/tidb/v3.0/deploy-test-cluster-using-docker-compose
本文档介绍如何在单机上通过 Docker Compose 快速一键部署一套 TiDB 测试集群。Docker Compose 可以通过一个 YAML 文件定义多个容器的应用服务，然后一键启动或停止。
确保你的机器上已安装：
- Docker（17.06.0 及以上版本）
- Docker Compose
- Git
1.1、下载tidb-docker-compose
1 2 3 4 5 6 7 8 | [root@docker35 ~]# git clone https://github.com/pingcap/tidb-docker-compose.git Cloning into 'tidb-docker-compose'... remote: Enumerating objects: 8, done. remote: Counting objects: 100% (8/8), done. remote: Compressing objects: 100% (8/8), done. remote: Total 554 (delta 0), reused 6 (delta 0), pack-reused 546 Receiving objects: 100% (554/554), 284.17 KiB | 204.00 KiB/s, done. Resolving deltas: 100% (243/243), done. |
1.2、创建并启动集群
创建并启动集群，获取最新 Docker 镜像：
1 | cd tidb-docker-compose && docker-compose pull && docker-compose up -d |

二、访问集群
2.1、访问TiDB
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 | [root@docker35 tidb-docker-compose]# mysql -h 127.0.0.1 -P 4000 -u root Welcome to the MySQL monitor. Commands end with ; or \g.

2.2、访问集群 Grafana 监控
访问集群 Grafana 监控页面：http://localhost:3000 默认用户名和密码均为 admin。如下内容都可以监控到：
例如：
2.3、集群数据可视化
集群数据可视化（https://github.com/pingcap/tidb-vision）：http://localhost:8010
如果启用了 tidb-vision，可以通过 http://localhost:8010 查看。
2.4、访问Spark Web UI
三、自定义集群
在完成快速部署后，以下组件已默认部署：3 个 PD，3 个 TiKV，1 个 TiDB 和监控组件 Prometheus，Pushgateway，Grafana 以及 tidb-vision。
如果想自定义集群，可以直接修改 docker-compose.yml，但是手动修改比较繁琐而且容易出错，强烈建议使用 Helm 模板引擎生成 docker-compose.yml 文件。
