备注:

shared_scripts 目录存放虚拟机初始化的系统配置脚本。
1. setup.sh：Vagrantfile 调用shell文件进行系统配置，此脚本内容是执行root_setup.sh
2. root_setup.sh：设置主机名与sshd配置，调用shell_init_os.sh 脚本
3. shell_init_os.sh：对安装tidb前进行操作系统进行配置。
4. tiup_deploy.sh：安装tiup工具软件
Vagrantfile 文件是vagrant 的虚拟机配置文件

自动修复集群存在的潜在风险：

# tiup cluster check ~/topology.yaml --apply --user root

部署 TiDB 集群：

# tiup cluster deploy tidb-test v5.4.1 ./topology.yaml --user root

以上部署示例中：

tidb-test 为部署的集群名称。
v5.4.1 为部署的集群版本，可以通过执行 tiup list tidb 来查看 TiUP 支持的最新可用版本。
初始化配置文件为 topology.yaml。
--user root 表示通过 root 用户登录到目标主机完成集群部署，该用户需要有 ssh 到目标机器的权限，并且在目标机器有 sudo 权限。也可以用其他有 ssh 和 sudo 权限的用户完成部署。
[-i] 及 [-p] 为可选项，如果已经配置免密登录目标机，则不需填写。否则选择其一即可，[-i] 为可登录到目标机的 root 用户（或 --user 指定的其他用户）的私钥，也可使用 [-p] 交互式输入该用户的密码。

预期日志结尾输出 Deployed clustertidb-testsuccessfully 关键词，表示部署成功。

查看 TiUP 管理的集群情况

# tiup cluster list

TiUP 支持管理多个 TiDB 集群，该命令会输出当前通过 TiUP cluster 管理的所有集群信息，包括集群名称、部署用户、版本、密钥信息等。

检查部署的 TiDB 集群情况

# tiup cluster display tidb-test

启动集群

安全启动是 TiUP cluster 从 v1.9.0 起引入的一种新的启动方式，采用该方式启动数据库可以提高数据库安全性。推荐使用安全启动。

安全启动后，TiUP 会自动生成 TiDB root 用户的密码，并在命令行界面返回密码。

注意：

使用安全启动方式后，不能通过无密码的 root 用户登录数据库，你需要记录命令行返回的密码进行后续操作。
该自动生成的密码只会返回一次，如果没有记录或者忘记该密码，请参照忘记 root 密码修改密码。

方式一：安全启动
