備注:

• shared_scripts 目錄存放虛拟機初始化的系統配置腳本。

1. setup.sh：Vagrantfile 調用shell檔案進行系統配置，此腳本内容是執行root_setup.sh
2. root_setup.sh：設定主機名與sshd配置，調用shell_init_os.sh 腳本
3. shell_init_os.sh：對安裝tidb前進行作業系統進行配置。
4. tiup_deploy.sh：安裝tiup工具軟體

• Vagrantfile 檔案是vagrant 的虛拟機配置檔案

• 自動修複叢集存在的潛在風險：

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

• 部署 TiDB 叢集：

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

以上部署示例中：

• ​

  ​tidb-test​

  ​ 為部署的叢集名稱。
• ​

  ​v5.4.1​

  ​​ 為部署的叢集版本，可以通過執行​

  ​tiup list tidb​

  ​ 來檢視 TiUP 支援的最新可用版本。
• 初始化配置檔案為​

  ​topology.yaml​

  ​。
• ​

  ​--user root​

  ​ 表示通過 root 使用者登入到目标主機完成叢集部署，該使用者需要有 ssh 到目标機器的權限，并且在目标機器有 sudo 權限。也可以用其他有 ssh 和 sudo 權限的使用者完成部署。
• [-i] 及 [-p] 為可選項，如果已經配置免密登入目标機，則不需填寫。否則選擇其一即可，[-i] 為可登入到目标機的 root 使用者（或 --user 指定的其他使用者）的私鑰，也可使用 [-p] 互動式輸入該使用者的密碼。

​​tidb-test​

檢視 TiUP 管理的叢集情況

# tiup cluster list      

TiUP 支援管理多個 TiDB 叢集，該指令會輸出目前通過 TiUP cluster 管理的所有叢集資訊，包括叢集名稱、部署使用者、版本、密鑰資訊等。

檢查部署的 TiDB 叢集情況

# tiup cluster display tidb-test      

啟動叢集

安全啟動是 TiUP cluster 從 v1.9.0 起引入的一種新的啟動方式，采用該方式啟動資料庫可以提高資料庫安全性。推薦使用安全啟動。

安全啟動後，TiUP 會自動生成 TiDB root 使用者的密碼，并在指令行界面傳回密碼。

注意：

• 使用安全啟動方式後，不能通過無密碼的 root 使用者登入資料庫，你需要記錄指令行傳回的密碼進行後續操作。
• 該自動生成的密碼隻會傳回一次，如果沒有記錄或者忘記該密碼，請參照​​忘記 root 密碼​​修改密碼。
