如何将redis数据库从一个服务器移动到另一个服务器？ [英] How do I move a redis database from one server to another?

问题描述

我目前有一个运行在一个云实例上的实时redis服务器，我想将这个redis服务器迁移到一个新的云实例，并将该实例用作我的新redis服务器。如果是MySQL，我将从旧服务器导出数据库并将其导入新服务器。我应该怎么做这与redis？

I currently have a live redis server running on a cloud instance and I want to migrate this redis server to a new cloud instance and use that instance as my new redis server. If it were MySQL, I would export the DB from the old server and import it into the new server. How should I do this with redis?

P.S .:我不想设置复制。我想将redis服务器完全迁移到一个新实例。

P.S.: I'm not looking to set-up replication. I want to completely migrate the redis server to a new instance.

推荐答案

将数据库的镜像保存到dump.rdb要么运行 BGSAVE 或 SAVE 。这将在与redis服务器相同的文件夹中创建一个名为dump.rdb的文件。查看所有服务器命令的列表。

Save a spanshot of the database into a dump.rdb by either running BGSAVE or SAVE from the command line. This will create a file named dump.rdb in the same folder as your redis server. See a list of all server commands.

复制此dump.rdb到您要迁移到的其他redis服务器。当redis启动时，它会寻找这个文件来初始化数据库。

Copy this dump.rdb to the other redis server you want to migrate to. When redis starts up, it looks for this file to initialize the database from.
