TiDB v7.1.0版本测试部署在线扩容与数据迁移

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 Successfully set mirror to /tidb-setup/tidb-community-server-v7.1.0-linux-amd64 Detected shell: bash Shell profile: /root/.bash_profile Installed path: /root/.tiup/bin/tiup=============================================== 1. source /root/.bash_profile 2.

初始化集群拓扑文件[首次部署,排除192.168.31.56,然后在进行扩容操作]

进行按集群拓扑文件对服务器条件检测

[root@192_168_31_50_TiDB tidb-community-server-v7.1.0-linux-amd64]# tiup cluster check ./tidb_install.yaml --user root -p

Input SSH password:

安装前条件检测结果如下:可以看到结果中有部份fail或warn状态信息,可以能过增加修复参数 --apply 进行修复。
