Redis启动后是空的，虽然有.rdb文件 [英] Redis is empty after startup, altough there is an .rdb file

问题描述

在我的 redis-cli 中运行关闭保存"后，等待保存"命令完成(遵循 redis 日志)并备份我的 redis .rdb 文件，我尝试从头开始启动 redis 服务器，然后它以一个空的 DB 开始(dbsize =0!!!).

After I ran "shutdown save" in my redis-cli, waited for the "save" command to finish (followed the redis log) and backed up my redis .rdb file, I tried starting the redis server from the begining and it was started with an empty DB (dbsize =0!!!).

我能做什么?如何从 .rdb 文件恢复我的 redis?

What can I do ? How can I restore my redis from the .rdb file?

推荐答案

问题确实出在我的配置文件中.我将名为 tal.rdb 的 .rdb 文件保存为 old-tal.rdb 所以它不会受到影响.然后，我再次启动了我的 Redis 服务器，看到它有 0 个键，插入了 10000 个键并运行了 save" 命令，结果，我看到它有在正确的目录路径中创建了一个文件 dump.rdb(Redis .rdb files 的默认 dbfilename)，尽管在配置文件中 dbfilename 是 tal.rdb，所以我知道我的配置文件是坏的.为了解决这个问题，我用一个备份文件替换了配置文件，并用一个副本重新启动了我的 Redistal.rdb 然后它正确启动(10M 键).谢谢大家！

The problem was indeed in my configuration file. I saved my .rdb file called tal.rdb as old-tal.rdb so it won't be effected. Then, I've started my Redis server again, saw it has 0 keys, inserted 10000 keys and ran the save"command and, as a result, I saw it has created a file dump.rdb (the default dbfilename for Redis .rdb files) in the correct directory path, although in the configuration file the dbfilename was tal.rdb, so I understand my configuration file was bad. To fix this, I replaced the configuration file with a backed up file and restarted my Redis with a copy of tal.rdb and then it was started correctly (10M keys). Thanks everyone!
