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

[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:

cd tidb-docker-compose && docker-compose pull && docker-compose up -d

执行过程:

[root@docker35 ~]# cd tidb-docker-compose/ [root@docker35 tidb-docker-compose]# ll total 64 drwxr-xr-x 3 root root 60 Apr 14 15:13 compose drwxr-xr-x 4 root root 4096 Apr 14 15:13 config drwxr-xr-x 3 root root 59 Apr 14 15:13 dashboard-installer drwxr-xr-x 3 root root 19 Apr 14 15:13 docker -rw-r--r-- 1 root root 11343 Apr 14 15:13 docker-compose-binlog.yml -rw-r--r-- 1 root root 292 Apr 14 15:13 docker-compose-test.yml -rw-r--r-- 1 root root 1566 Apr 14 15:13 docker-compose-tiflash-nightly.yml -rw-r--r-- 1 root root 5445 Apr 14 15:13 docker-compose.yml -rw-r--r-- 1 root root 4736 Apr 14 15:13 docker-swarm.yml -rw-r--r-- 1 root root 11294 Apr 14 15:13 LICENSE drwxr-xr-x 2 root root 24 Apr 14 15:13 pd -rw-r--r-- 1 root root 11335 Apr 14 15:13 README.md drwxr-xr-x 2 root root 24 Apr 14 15:13 tidb drwxr-xr-x 2 root root 24 Apr 14 15:13 tidb-binlog drwxr-xr-x 2 root root 24 Apr 14 15:13 tidb-vision drwxr-xr-x 2 root root 24 Apr 14 15:13 tikv drwxr-xr-x 6 root root 95 Apr 14 15:13 tispark drwxr-xr-x 2 root root 29 Apr 14 15:13 tools [root@docker35 tidb-docker-compose]# du -sh . 3.3M .

二、访问集群

2.1、访问TiDB

[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. Your MySQL connection id is 5 Server version: 5.7.25-TiDB-v5.0.0 TiDB Server (Apache License 2.0) Community Edition, MySQL 5.7 compatible Copyright (c) 2000, 2020, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> show databases; +--------------------+ | Database | +--------------------+ | INFORMATION_SCHEMA | | METRICS_SCHEMA | | PERFORMANCE_SCHEMA | | mysql | | test | +--------------------+ 5 rows in set (0.00 sec) mysql> create database lhrdb charset utf8mb4; Query OK, 0 rows affected (0.07 sec) mysql> show databases; +--------------------+ | Database | +--------------------+ | INFORMATION_SCHEMA | | METRICS_SCHEMA | | PERFORMANCE_SCHEMA | | lhrdb | | mysql | | test | +--------------------+ 6 rows in set (0.00 sec)

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

http://192.168.66.35:8080/

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。

安装 Helm

Helm 可以用作模板渲染引擎,只需要下载其 binary 文件即可以使用。

curl https://raw.githubusercontent.com/Kubernetes/helm/master/scripts/get | bash

如果是 Mac 系统,也可以通过 Homebrew 安装:

brew install kubernetes-helm

下载 tidb-docker-compose

git clone https://github.com/pingcap/tidb-docker-compose.git

自定义集群

cd tidb-docker-compose && cp compose/values.yaml values.yaml && vim values.yaml

修改 values.yaml 里面的配置,例如集群规模,TiDB 镜像版本等。

tidb-vision 是 TiDB 集群可视化页面,可以可视化地显示 PD 对 TiKV 数据的调度。如果不想部署该组件,可以将 tidbVision 项留空。

PD,TiKV,TiDB 和 tidb-vision 支持从 GitHub 源码或本地文件构建 Docker 镜像,供开发测试使用。

如果希望从本地已编译好的 binary 文件构建 PD,TiKV 或 TiDB 镜像,需要将其 image 字段留空,并将已编译好的 binary 拷贝到对应的 pd/bin/pd-server,tikv/bin/tikv-server,tidb/bin/tidb-server。

如果希望从本地构建 tidb-vision 镜像,需要将其 image 字段留空,并将 tidb-vision 项目拷贝到 tidb-vision/tidb-vision。

生成 docker-compose.yml 文件

helm template -f values.yaml compose > generated-docker-compose.yml

使用生成的 docker-compose.yml 创建并启动集群

获取最新 Docker 镜像:

docker-compose -f generated-docker-compose.yml pull docker-compose -f generated-docker-compose.yml up -d

访问集群

mysql -h 127.0.0.1 -P 4000 -u root

使用Docker-Compose快速部署TiDB集群环境

四、访问 Spark shell 并加载 TiSpark

向 TiDB 集群中插入一些样本数据:

docker-compose exec tispark-master bash && cd /opt/spark/data/tispark-sample-data && mysql -h tidb -P 4000 -u root < dss.ddl

当样本数据加载到 TiDB 集群之后,可以使用 docker-compose exec tispark-master /opt/spark/bin/spark-shell 来访问 Spark shell。

docker-compose exec tispark-master /opt/spark/bin/spark-shell ... Spark context available as 'sc' (master = local[*], app id = local-1527045927617). Spark session available as 'spark'. Welcome to ____ __ / __/__ ___ _____/ /__ _\ \/ _ \/ _ `/ __/ '_/ /___/ .__/\_,_/_/ /_/\_\ version 2.1.1 /_/ Using Scala version 2.11.8 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_172) Type in expressions to have them evaluated. Type :help for more information. scala> import org.apache.spark.sql.TiContext ... scala> val ti = new TiContext(spark) ... scala> ti.tidbMapDatabase("TPCH_001") ... scala> spark.sql("select count(*) from lineitem").show +--------+ |count(1)| +--------+ | 60175| +--------+

你也可以通过 Python 或 R 来访问 Spark:

docker-compose exec tispark-master /opt/spark/bin/pyspark && docker-compose exec tispark-master /opt/spark/bin/sparkR

更多关于 TiSpark 的信息,参见 TiSpark 的详细文档,连接:https://docs.pingcap.com/zh/tidb/v3.0/get-started-with-tispark。
