听说Oracle有个oracle always free计划,所以赶紧申请了个Oracle Cloud的账号,主要是用来FQ用的,之前用过Google的,不过只有1年的期限,由此看来这个很吸引人,搭建的V兔Ray
也算稳定,看了看其它可用的东西,自治数据库(ADW)看起来也不错,不过个人感觉更适合大公司吧,目前只是把个人的数据库文件放上面,做个备份。
另外一个就是对象存储了,不过空间有点小,暂时我也用不到,主要是熟悉一下oci的SDK,体验一下Oracle的服务,上面说的自治数据库(ADW)是用的cx_Oracle
库,当然这个库也是基于oci
的,下面就记录一下oci
的简单用法
1. 添加API秘钥
这一步很简单,主要就是会生成一些配置参数,然后把这些参数复制一下,粘贴到对应操作系统的~/.oci/config
文件下(需要自行创建),除了会自动生成这个配置,还会让你下载一个私钥,下载完成后,放在和config
文件相同路径即可,然后需要在config
文件内修改最后一行内容,填写私钥的名称,最好填写私钥的绝对路径
2.代码
先装一下库,pip install oci
,最需要注意的是代码中的compartment_id
参数,我找了好半天,代码中有注释说明
