一. 在Linux机器上配置Command Line Interface。

1. Python版本号大于等于2.7

[root@repo ~]$ python --version

2. 安装的用户要有sudo权限

[root@repo ~]# visudo

符合条件

2. 下载并安装CLI

[lirou@node3 ~]$ curl -L "https://raw.githubusercontent.com/oracle/oci-cli/master/scripts/install/install.sh" | bash

查看

3. 自动生成配置CLI配制文件

此配置文件用于认证

获取用户OCID：

获取租户OCID

4. 更新用户密钥

查看密钥放置的位置：

查看密钥内容

添加密钥

4. 测试是否配置成功

二. 批量部署节点机脚本
