一、测试keyring file

1.1 当keyring file文件丢失或者被篡改

结论：不影响当前正在运行的数据库，但是在重启服务后会启动失败出现报错。

tail -n 100 /var/log/mysql/error.log

报错信息如下：

将备份的keyring file文件还原，重新启动服务后，数据库启动正常，原来加密的表正常。说明定期备份keyring file文件很重要。

三、测试mysqldump备份文件

模拟文件被泄漏。对启用TDE加密的数据库(某些表加密)执行mysqldump逻辑备份。将mysqldump文件拷贝到其他mysql服务器上执行导入测试

3.1 在未启用加密插件的MySQL上导入备份

在未启用加密插件的mysql示例上(我测试社区版)，导入备份文件报错且数据库和表都未创建。

mysql > ERROR 3185 (HY000) at line 27: Can't find master key from keyring, please check in the server log if a keyring plugin is loaded and initialized successfully.Operation failed with exitcode 1

通过notepad打开mysqldump文件，我们可以看到创建表的SQL语句含有ENCRYPTION='Y'加密操作，没有启用TDE的情况下加上这句肯定会报错，我们将文件里面的ENCRYPTION='Y'都使用空替换，重新保存mysqldump文件。
