摘　　要：针对传统的数据迁移方法中存在的耗时长问题,提出基于Linux容器的交互式数据动态迁移方法。首先搭建规则数据库作为数据动态迁移的应用准则,在源主机上准备需要进行迁移的数据,并利用Linux容器在服务器中生成镜像文件实现文件备份。通过设置数据迁移更新周期、停机迁移和迁移数据校验处理三个步骤实现交互式迁移数据的动态更新。为了验证设计的数据动态迁移方法的可行性设计对比实验,通过与传统迁移方法的对比得出结论:基于Linux容器的交互式数据动态迁移方法的平均宕机时间节省了0.422s,在累计总迁移时间方面节省了8.032s。To solve the time-consuming problem in traditional data migration methods,an interactive data dynamic migration method based on Linux container is proposed. Firstly,the rule database is built as the application guideline of data dynamic migration,the data that needs to be migrated is prepared on the source host,and the mirror file is generated in the server by Linux container to realize file backup.The dynamic update of interactive migration data is realized by setting up three steps: update cycle of data migration,downtime migration and verification processing of migration data. In order to verify the feasibility of the designed data dynamic migration method,a comparison experiment was designed to draw the conclusion that the average downtime of the interactive data dynamic migration method based on Linux containers was 0.422 s,and the cumulative total migration time was 8.032 s.
