3 安装部署TiDB
3.1 下载安装部署包
将tidb-community-server-v7.5.4-linux-arm64.tar.gz上传至hdp-01服务器上
mkdir /data/tidb
cd /data/tidb
wget https://download.pingcap.org/tidb-community-server-v7.5.4-linux-arm64.tar.gz
tar -xvf tidb-community-server-v7.5.4-linux-arm64.tar.gz
3.2 tidb用户
3.2.1 增加tidb用户及配置相关密码
#hdp-01、hdp-02、hdp-03、hdp-04
useraddr tidb
passwd tidb
3.2.2 tidb用户免密
#hdp-01
[tidb@hdp-01 ~]$ su - tidb
[tidb@hdp-01 ~]$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/tidb/.ssh/id_rsa):
Created directory '/home/tidb/.ssh'.
Enter passphrase (empty for no passphrase):

3.3.3 配置sudo权限
#hdp-01、hdp-02、hdp-03、hdp-04
# 在/etc/sudoers添加下列条目
tidb ALL=(ALL) NOPASSWD:ALL
3.3 部署TiUP环境
# hdp-01
[root@hdp-warehouse-001 tidb-community-server-v7.5.4-linux-arm64]# sh local_install.sh
Disable telemetry success
Successfully set mirror to /data/tidb/tidb-community-server-v7.5.4-linux-arm64
Detected shell: bash
Shell profile: /root/.bash_profile
/root/.bash_profile has been modified to to add tiup to PATH
open a new terminal or source /root/.bash_profile to use it
Installed path: /root/.tiup/bin/tiup
===============================================
1. source /root/.bash_profile
2. Have a try: tiup playground
# 刷新环境变量
[root@hdp-warehouse-001 tidb-community-server-v7.5.4-linux-arm64]# source /root/.bash_profile
# 确认环境变量生效
[root@hdp-warehouse-001 tidb-community-server-v7.5.4-linux-arm64]# which tiup
/root/.tiup/bin/tiup
3.4 修改配置文件
3.4.1 生成配置文件
# hdp-01
[root@hdp-warehouse-001 tidb-community-server-v7.5.4-linux-arm64]# tiup cluster template > topology.yaml
A new version of cluster is available: -> v1.16.0
To update this component: tiup update cluster
To update all components: tiup update --all
The component `cluster` version is not installed; downloading from repository.
3.4.2 修改配置文件topology.yaml
