前言

由於公司業務需求，我們需要大量建立虛擬機器執行任務，任務運行完後需要銷毀，以節省資源。
我們大量建立虛擬方式是通過Oracle雲提供的bash介面，所以我們第一步就是要建立bash環境

一. 在Linux機器上配置Command Line Interface。1. Python版本號碼大於等於2.7

[[email protected] ~]$ python --version

2. 安裝的使用者要有sudo許可權

[[email protected] ~]# visudo

符合條件

2. 下載並安裝CLI

[[email protected] ~]$ curl -L "https://raw.githubusercontent.com/oracle/oci-cli/master/scripts/install/install.sh" | bash

查看

3. 自動組建組態CLI配製檔案

此設定檔用於認證

擷取使用者OCID：

擷取租戶OCID

4. 更新使用者密鑰

查看密鑰放置的位置：

查看金鑰產製原料

添加密鑰

4. 測試是否配置成功

二. 批量部署節點機指令碼

注意 :

• 指令碼使用
  • 建立節點機：./nodes_ocvh.sh create 3
  • 刪除節點：./nodes_ocvh.sh delete 2
