TiDB v7.1.0版本 相关（部署、在线扩容、数据迁移）测试
一、服务器信息参数

二、TiDB v7.1.0 离线安装包下载
本次采用在官方下载页面选择对应版本的 TiDB server 离线镜像包（包含 TiUP 离线组件包）。需要同时下载 TiDB-community-server 软件包和 TiDB-community-toolkit 软件包。
TiDB-community-server 软件包： https://download.pingcap.org/tidb-community-server-v7.1.0-linux-amd64.tar.gz
TiDB-community-toolkit 软件包： https://download.pingcap.org/tidb-community-toolkit-v7.1.0-linux-amd64.tar.gz
三、上传安装包到 192_168_31_50_TiDB 主机的 /home目录，
可以使用以下两种方式
（1）命令方式上传文件到指定的服务器：scp 上传文件的包名子 root@上传服务器地址:/上传路径
（2）工具方式上传文件到指定的服务器：可以使用winscp、xsftp等工具 
上传完成后，解压上述两个包文件 [root@192_168_31_50_TiDB tidb-community-server-v7.1.0-linux-amd64]# sh local_install.sh
Disable telemetry success

通过TiDB Dashboard查看集群信息，可以看到TiKV节点原3节点扩容成4节点。
数据迁移测试，从 MySql --> TiDB 数据导入测试，环境信息介绍，目前有mysql数据
| 序号 | 地址 | 数据库类型 | 数据库版本 | 数据库名 | 账号 | 密码 | | -- | ------------- | ----- | ------ | -------- | -------- | --------- | | 1 | 192.168.31.13 | mysql | 5.7.40 | jsh_erp | jsh_erp | P@ssw0rd | | 2 | 192.168.31.50 | TiDB | 7.1.0 | | root | P@ssw0rd |
进入TiDB主机把相关迁移工具配置好，并完成环境变量的配置 数据迁出工具使用Dumpling
| 使用场景 | 用于将数据从 MySQL/TiDB 进行全量导出 |
|---|---|
| 上游 | MySQL，TiDB |
| 下游（输出文件） | SQL，CSV |
| 主要优势 | * 支持全新的 table-filter，筛选数据更加方便 |
- 支持导出到 Amazon S3 云盘| |使用限制|* 如果导出后计划往非 TiDB 的数据库恢复，建议使用 Dumpling。
- 如果导出后计划往另一个 TiDB 恢复，建议使用BR|
数据迁入工具使用TiDB Lightning
| 使用场景 | 用于将数据全量导入到 TiDB |
|---|---|
| 上游（输入源文件） | * Dumpling 输出的文件 |
- 从 Amazon Aurora 或 Apache Hive 导出的 Parquet 文件
- CSV 文件
- 从本地盘或 Amazon S3 云盘读取数据| |下游|TiDB| |主要优势|* 支持快速导入大量数据，实现快速初始化 TiDB 集群的指定表
- 支持断点续传
- 支持数据过滤| |使用限制|* 如果使用
物理导入模式
进行数据导入，TiDB Lightning 运行后，TiDB 集群将无法正常对外提供服务。
- 如果你不希望 TiDB 集群的对外服务受到影响，可以参考 TiDB Lightning
逻辑导入模式
中的硬件需求与部署方式进行数据导入。
解压dumping与tidb-lightning包文件，如命令如下
[root@192_168_31_50_TiDB tidb-community-toolkit-v7.1.0-linux-amd64]# tar -xvf dumpling-v7.1.0-linux-amd64.tar.gz
[root@192_168_31_50_TiDB tidb-community-toolkit-v7.1.0-linux-amd64]# tar -xvf tidb-lightning-v7.1.0-linux-amd64.tar.gz
配置环境变量，让dumping与tidb-lightning命令生效，新增内容为:/tidb-setup/tidb-community-toolkit-v7.1.0-linux-amd64，完成后如下信息：
[root@192_168_31_50_TiDB tidb-community-toolkit-v7.1.0-linux-amd64]# vim /root/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
export PATH=/root/.tiup/bin:/tidb-setup/tidb-community-toolkit-v7.1.0-linux-amd64:$PATH
数据导出位置/dumping_erp_db
[root@192_168_31_50_TiDB /]# mkdir dumping_erp_db
利用dumping命令把192.168.31.13的jsh_erp数据库导出在/dumping_erp_db文件夹中，命令如下：
[root@192_168_31_50_TiDB /]# dumpling -h192.168.31.13 -ujsh_erp -p'P@ssw0rd' -P3306 --filetype sql -t 2 -o /dumpling_erp_db/ -r 20000 -F 256MiB -B jsh_erp

导入数据到TiDB数据库，此次采用的是“逻辑导入”，因为此次数据量小50GB，首先新建Tidb-lightning配置文件，配置文件信息如下：
[lightning]
level = "info"
file = "tidb-lightning.log"
max-size = 128 # MB
max-days = 28
max-backups = 14
check-requirements = true
[mydumper]
data-source-dir = "/dumpling_erp_db"
[tikv-importer]
backend = "tidb"
on-duplicate = "replace"
[tidb]
host = "192.168.31.50"
port = 4000
user = "root"
password = "P@ssw0rd"
log-level = "error"
执行导入命令 tidb-lightning -config tidb-lightning.toml > tidb-lightning.log
[root@192_168_31_50_TiDB tidb-setup]# tidb-lightning -config tidb-lightning.toml > tidb-lightning.log
导入成功后日志如下：

数据库导入成功，我验证一下原有jsh_erp数据库与TiDB里的jsh_erp是否一致，由于数据库自身较小，本次使用beyong Compare工具进行比对（对比前把原有数据库与现有数据库进行导出），数据对比结果如下图：
