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
